How To Patch Test a New Skincare Product Correctly, According to Dermatologists
'It's a good idea to patch test products when using them for the first time, especially if you have sensitive skin, to identify any adverse reactions before you apply the product to a larger area,' says Dendy Engelman, MD, FACMS, FAAD, board-certified cosmetic dermatologist and Mohs surgeon at the Shafer Clinic in New York City. 'It's a safer way to ensure a product is compatible with your skin before regular use.'
Now you're probably wondering, what is patch testing exactly? To help break down the procedure, we turned to two dermatologists to get the scoop, including the best way to do it at home. Below, learn everything there is to know about patch testing. Dendy Engelman, MD, FACMS, FAAD, is a board-certified cosmetic dermatologist and Mohs surgeon at the Shafer Clinic in New York City.
Kseniya Kobets, MD, is the Director of Dermatology at Montefiore Einstein Advanced Care.'Dermatologists or allergy doctors often use patch testing to determine if a specific ingredient or substance can be causing someone to have rashes or skin reactions from contact with the skin, skincare, or the environment,' says Kseniya Kobets, MD, Director of Dermatology at Montefiore Einstein Advanced Care. The test is applied in the office and includes a series of 'patches' of concentrated allergens that come into direct contact with the skin. This is typically applied as a bandage with six to twelve patches per strip. "It's checked over a few days to a week to check for a reaction or delayed reaction on your skin after exposure to common and reported allergens," explains Dr. Kobets.
While the in-office treatment is recommended by experts, you can also try to patch test at home. According to Dr. Kobets, you should apply a small amount of a cream or other topical you'd like to test to the inner part of your arm and monitor if it causes a reaction within hours to 24 hours. However, she warns that this is not a precise method. At-home testing involves using a product that can contain various ingredients. If you do have an allergy, you wouldn't know which component is causing the reaction. In-office patch testing, on the other hand, uses individually identified allergens at higher concentrations, which are more likely to show a reaction and offer a more targeted result.
It's best to do a patch test every time you try a new hair or skin product, especially if you have sensitive skin or a history of atopic dermatitis or eczema. 'It's also important to test products that contain active ingredients or fragrances, which are more likely to cause irritation,' says Dr. Engelman. 'Patch testing is best done at least 24 to 48 hours before using the product widely, to give enough time to spot any reaction.'
If you choose to perform a patch test at home, Dr. Engelman shares these step-by-step instructions:
Choose a small, discreet area of skin to test, such as behind the ear, the inner forearm, or your foot.
Apply a small amount of the product to that spot, spreading it thinly and evenly.
Cover the area with a bandage or leave it uncovered if the product dries quickly.
Wait at least 24 to 48 hours without washing or disturbing the spot.
Check the area for any signs of redness, itching, swelling, or irritation.
If there's no reaction, the product is likely safe to use on your skin.
If irritation appears, avoid using the product and consult a dermatologist if needed.
After completing these steps, it is important to take action should a reaction occur. 'It will be easy to tell if a patch test reveals an adverse reaction—you'll likely notice redness, itching, small bumps, and/or unusual warmth, which can signal early irritation,' Dr. Engelman says. 'If your patch test causes a reaction, stop using the product right away and gently wash the area with cool water and a fragrance-free cleanser. Applying a gentle, fragrance-free moisturizer can help soothe the skin. If the reaction gets worse or doesn't improve in a day or so, consult your dermatologist for guidance.'
It's important to note that you can still have a delayed reaction even if your patch test showed no immediate issues. 'Some sensitivities develop slowly and may only appear after repeated or prolonged use of a product,' Dr. Engelman says. 'The patch test checks for quick reactions but doesn't always catch long-term irritation or allergies. Always watch your skin closely when trying something new, even after a clear patch test.'
If you have a history of reactive skin and it is only getting worse over time, then Dr. Kobets suggests getting a professional patch test in consultation with a dermatologist.
As far as what to expect during a professional patch test, the process is fairly straightforward. A dermatologist will typically apply standard allergens on your back unless you already have an active rash, acne, or reaction on the area. 'You're advised to avoid exposure to sun and moisture, avoid scratching, and to come back at a specific time throughout the week for the first reading at 48 hours and then a second reading at 72 to 96 hours,' Dr. Kobets explains.
Your dermatologist or allergist may ask you to avoid specific medications, such as antihistamines and topical or oral steroids, for a specific number of days before the testing, as they can interfere with the results, adds Dr. Kobets. 'You may want to keep a list of products you're allergic to or sensitive to, and note a common unifying ingredient that reappears in all of these,' she adds.
If you have sensitive skin or suspect a new product may trigger a reaction, patch testing is a good idea. Going the DIY route can be fine, but keep in mind that it won't always accurately predict a reaction. 'You should see a professional for a patch test if you have persistent or severe skin reactions that don't improve with home care,' Dr. Engelman says. 'It's especially important if you experience widespread redness, swelling, blistering, or intense itching after using products. A dermatologist can perform a more thorough patch test to identify specific allergens or irritants. They can also recommend personalized treatment and help you avoid triggers in the future.'

Derms Reveal What Really Works for Cellulite—and What Doesn't
Every item on this page was chosen by an ELLE editor. We may earn commission on some of the items you choose to buy. We're in the peak of summer, which means lighter layers, lots of sunscreen, and happy hours everywhere. It also means showing off much more skin, with curves and tan lines peeking out from our two-piece swimsuits or shorts. When looking in the mirror, some may not notice any changes, while others might see a slight development of cellulite. It's no secret that cellulite hasn't had the best PR, leading many of us with the dimpled appearance on our bodies to search high and low for relief. Results include a laundry list of products that claim to firm, tighten, and eliminate cellulite altogether. Luckily, we're here to quiet the storm brewing in your head. A hard truth: cellulite can't be fully eliminated, but it can be effectively managed and treated with the right products, tools, and at-home routines. Ahead, we tapped NYC-based board-certified dermatologist Dr. Dendy Engelman to learn all about cellulite and which at-home practices and products are best for treating it. Not to be confused with stretch marks or 'tiger stripes,' as many would call them, cellulite 'is a common, harmless skin condition that occurs when fat cells beneath the skin push up against connective tissue, causing the skin above it to pucker or dimple,' explains Dr. Engelman, a board-certified dermatologist at Shafer Clinic. If your summer uniform consists of wearing bikinis and shorts a lot, you might have noticed the dimpled appearance on your lower body, including thighs, butt, and hips, 'and sometimes the abdomen or arms,' Dr. Engelman adds. 'Cellulite is more prevalent in women than men due to differences in how fat, muscle, and connective tissue are distributed. In women, the connective tissue is arranged vertically, which makes it easier for fat cells to push through and create that dimpled appearance. Hormonal factors, genetics, and lifestyle can also influence its visibility. That said, cellulite is incredibly common and can affect people of all shapes, sizes, and fitness levels,' she notes. Dr. Engelman assures that cellulite is nothing to be worried about. In fact, 'it's a completely normal anatomical response influenced by hormones (especially estrogen), genetics, age, and even lifestyle factors such as diet and activity level. As we age and our skin loses elasticity, cellulite can become more visible. Reduced collagen production, decreased circulation, and changes in lymphatic flow can all contribute to its appearance,' she explains. Short answer? No. 'Cellulite is not something we can fully 'eliminate,' but we can minimize its appearance through a combination of lifestyle practices and topical or in-office treatments,' Dr. Engelman shares. The skin care market is ripe with corrective formulas that can improve the overall look and firmness of skin. However, it's important to be realistic about the results expected. 'No treatment, topical or otherwise, offers a permanent solution, as it is an important function of a healthy body. Cellulite is complex and multifactorial, so managing expectations and committing to consistent care is key. Improvement is possible, but long-term maintenance is typically required,' she advises. 'When it comes to treating cellulite, the most effective topical ingredients are those that stimulate circulation, reduce inflammation, and improve skin firmness and elasticity,' Dr. Engelman says. Think of your most firming, lifting, and plumping products, and there will likely be a common denominator: caffeine. 'Caffeine is one of the most popular and effective ingredients because it acts as a vasoconstrictor, temporarily tightening the skin, reducing puffiness, and increasing blood flow to targeted areas,' she explains. Of course, very few ingredients improve the overall look and texture of skin quite like retinol: 'A derivative of vitamin A, it supports long-term collagen production and skin cell turnover, which helps thicken the skin and improve its overall texture, making cellulite less visible over time. Peptides are another similar key group of ingredients that work by signaling the skin to produce more collagen and elastin, ultimately helping to firm and smooth the surface.' Dr. Engelman adds that 'botanical extracts like Centella Asiatica, also known as gotu kola, are valued for their ability to improve microcirculation and support connective tissue.' Dr. Engelman advises using the aforementioned ingredients, but also suggests Arnica Montana extract, which she says isn't a traditional cellulite treatment but offers impressive results. 'It's known for its anti-inflammatory and soothing properties. Products like Arnicare Roll-On, which contain arnica, may help reduce puffiness and tenderness in areas prone to cellulite, especially when used after massage or physical activity,' she adds. However, she maintains that 'products with caffeine and retinol are among the most studied and effective for firming and smoothing the skin when used over time.' It takes more than just a cream or a massage tool to yield the results you desire. 'The best way to manage and reduce the appearance of cellulite is through a well-rounded approach that includes lifestyle habits, skin care, and, for some, in-office treatments. Regular massages, whether manual or with a roller, can help stimulate blood flow and encourage lymphatic drainage, both of which support healthier-looking skin and may reduce fluid retention,' Dr. Engelman instructs. You know what else helps? Water. 'Staying hydrated is also essential, as it helps keep the skin plump and supports proper lymphatic function.' Additionally, 'exercise, particularly strength training, builds muscle tone and minimizes the appearance of fat deposits that contribute to cellulite,' she says, adding that dry brushing could help boost circulation as it exfoliates. 'Lastly, a balanced, anti-inflammatory diet that's low in excess sugar and processed foods can improve skin quality and reduce bloating and water retention, all of which contribute to a smoother, healthier look,' she advises. 'If cellulite is the root cause of your skin concerns and you're seeking more dramatic, targeted improvement, professional treatments can be a game-changer,' Dr. Engelman explains. 'One option I recommend looking into is EMTONE, an FDA-approved cellulite treatment that combines targeted pressure energy with radio frequency to help tighten the skin. It works by stimulating circulation, breaking down fibrous bands, and helping the body eliminate fluid and waste retention, all of which contribute to the appearance of cellulite. It is non-invasive and works well for patients who want visible smoothing without surgery or downtime.' 'There are many creams and serums on the market targeted at cellulite, but the key is finding products that include active ingredients supported by science and that you'll actually use consistently,' she shares. This means looking beyond products traditionally designed for cellulite and paying attention to specific ingredients, such as retinol, peptides, and caffeine. Dr. Dendy Engelman is a NYC-based board-certified dermatologist at Shafer Clinic in Manhattan. As a leading publisher of fashion, lifestyle, and beauty content, is committed to highlighting the best products in various categories by personally testing the latest and most innovative products, interviewing countless experts, and vetting customer-loved items.

Dermatologists Say This Technique Is A Surefire Way To Shave Your swimsuit Line Without Irritation.
"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Whether you're a newbie or you've been shaving your swimsuit line for a long time, you know it can be a challenge to get through the process without skin irritation, razor burn, or itchy bumps. It's the collateral damage from wanting hairless lady parts. Indeed, removing the hair around your swimsuit bottom and pubic region can be time-consuming, painful, and even dangerous for your skin if it's not done properly. "This area features very delicate, sensitive skin," adds Debra Jaliman, MD, an assistant clinical professor of dermatology at the Icahn School of Medicine at Mount Sinai in New York City. "You really have to shave everything meticulously." Meet the experts: Debra Jaliman, MD, is an assistant clinical professor of dermatology at the Icahn School of Medicine at Mount Sinai in New York City. Lindsey Zubritsky, MD, is a dermatologist and an editor for the Journal of the American Academy of Dermatology. Dendy Engelman, MD, is a dermatologic surgeon at Shafer Clinic Fifth Avenue in New York City. Eileen Bischoff, is an aesthetician and hair-removal specialist at Eve Salon in New York City. Gina Charles, DO, is a family physician. Fumi Ozaki, is an aesthetician and electrologist in Redondo Beach, California. Still want to give it a go (totally optional, since the full bush trend is heating up social media right now)? Here are the strategies experts recommend to keep your swimsuit line looking smooth and your skin feeling comfortable. After all, the last thing you want is to deal with is pain or itchiness during a vacation or beach day. Is it bad to shave your swimsuit line? First of all, removing hair anywhere on your body is completely your decision—so don't feel pressured into shaving, waxing, or using any other hair removal method if you don't want to. But if you do choose to shave your swimsuit line, there are some risks to keep in mind. The pubic region grows hair that is 'thicker, coarser, and more curly," compared to most hair on the rest of the body, explains Lindsey Zubritsky, MD, a dermatologist and an editor for the Journal of the American Academy of Dermatology. That means if the hairs in that area aren't removed properly, they're more likely to grow back into the skin and cause razor bumps, also known as ingrown hairs. And once you develop an ingrown hair, the skin often gets red and itchy as a result. You might also experience razor burn when landscaping your swimsuit line, which is a type of skin irritation that happens when a razor is used on the same area of skin over and over again while shaving, Dr. Jaliman says. Razor burn can result in inflamed skin and small, red bumps, as well as itchiness and even a burning sensation. But if you take steps to care for the skin before and after you shave, you can prevent these problems altogether. Read on for more expert-approved shaving tips before you jump in the shower. Invest in a good razor Picking the right razor is crucial to ensuring your swimsuit line is smooth and bump-free. There are countless options out on the market, but you might want to start by picking one that has three or four blades rather than just one or two. "If there are more blades, it dispenses more pressure, allowing each blade to cut with less force but more effect," says Dendy Engelman, MD, a dermatologic surgeon at Shafer Clinic Fifth Avenue in New York City. In other words, you'll get a better, closer shave without having to swipe over the same area multiple times and risk cutting yourself or getting irritated. Another crucial point: "Choosing a firm, sturdy razor with soothing strips will make a huge difference," adds Eileen Bischoff, an aesthetician and hair-removal specialist at Eve Salon in New York City. But you can also consider a razor that you're comfortable with and know how to control, Dr. Jaliman adds. She personally likes to use the same type of razor she would use to get rid of peach fuzz on the face. But if you're in a pinch and don't have time to diligently shop for your next razor, you can try the one-use throwaway kind, too. Keep in mind that they can get the job done, but they're labeled "disposable" for a reason, Bischoff says. So make sure not to use them more than a few times at the very most to avoid injuring your skin with a dull, dirty blade. "They're not meant to be used for a month," Bischoff Silk TrimStyle Moisturizing Razor with swimsuit Trimmer This trimmer-razor combo may help prevent pubic irritation. It also has four customizable length settings for a comfortable trim. $18.87 at Smooth Colors Disposable Razors This disposable option comes with three precision blades for a closer, smoother shave. It also includes a moisture strip to offer lubrication and help prevent irritation. $9.92 at For Pubic Hair & Skin Designed to target trickier areas like the swimsuit line, this razor has a small head and a precision trimmer on the back of the blades. $14.97 at Prepare your skin for shaving. If you know you'll be shaving your swimsuit line in advance, stop using body lotions that contain retinol a few days ahead of time, Dr. Jaliman says. This category of ingredient can make the skin more irritable and sensitive, and make your skin less likely to tolerate hair removal without running into discomfort. And even though ingrown hairs are a very real risk when it comes to shaving your nether regions, it's not inevitable. One thing that helps is exfoliation, Dr. Jaliman says, who recommends using a soft body scrub or a wet washcloth to gently buff the area before shaving. If you omit exfoliating, you risk your razor driving dead skin and gunk into your pores, says Gina Charles, DO, a family physician and the owner of Serenity Aesthetics & Wellness. "Then it's harder to shave because you're going to be peeling off dead skin with your razor instead of the hair," Dr. Jaliman adds. But that's not all. It's also important to use warm water to hydrate and soften the skin and hairs before using your razor, Dr. Jaliman says. Spend about 10 minutes in warm water before you go to town on your swimsuit line. This will help soften the outer layer of your skin, make it easier to remove hair, and lessen your chances of getting razor burn, ingrown hairs, and other forms of irritation, says Fumi Ozaki, an aesthetician and electrologist in Redondo Beach, California. "After the 10 minutes are up, pat the skin to remove any excess water," she says. But make sure your skin is still damp when once you begin removing hair—dry shaving raises the risk of Exfoliating Body Polish This body scrub is crafted exfoliates the skin using coconut powder, but keeps it hydrated as well with ingredients such as jojoba oil, and black rice water. $14.00 at Thermale Avène Gentle Body Scrub. This exfoliating body scrub is abrasive. It also contains soothing ingredients such as jojoba oil. $30.00 at Buffer This pre-shave exfoliating bar preps the skin for a close, smooth shave without making it feel dry. It contains nourishing ingredients such as shea butter and aloe. $10.25 at Don't skip shaving cream. Always try to shave with a shaving gel, lotion or run-of-the-mill cream. You might think this is just a feel- and smell-good component to the process, but it's way more than that. "When you shave, you're shaving your skin, too," says Bischoff. "If you don't use enough shaving cream to create enough slip, you'll lightly abrade your skin, leaving it irritated." Ouch. Look out for tried-and-true moisturizing ingredients on product labels, such as shea butter, olive oil, and coconut oil, Dr. Engelman says. "These types of bases will give a proper buffer for your razor," she adds. You'll want to avoid shaving creams with fragrances as well, Dr. Jaliman says. Fragrances are often made using alcohol, she adds, which is often irritating to the skin. And try not to use soap as a replacement for shaving cream. Soap is often drying, which is particularly unhelpful when shaving an area of the body that's already sensitive and more prone to irritation, Dr. Jaliman adds. Once you've picked out a good shaving cream or gel, apply a thin layer to the area you're targeting. It should be thin enough that you can see the skin and hair shaft underneath so that you're provided enough lubrication while still reducing the need to make multiple passes on the same area of skin to fully remove the hair, says Intimate Grooming 2 in1 Cleanser and Shave Gel This translucent, fragrance-free formula lets you see what you're doing while shaving delicate areas. This will help you identify your direction of hair growth and prevent irritation. $9.79 at Cloud Luxury Shave Butter This shaving butter comes in a smooth whipped texture, and its infused with coconut milk, mango seed butter, and argan oil to soften skin and provide soothing lubrication for hair removal. $32.00 at and Rich Shaving Cream This cream may be used on all skin types and offers a neutral, ckean scent without added fragrances. $7.20 at Pay attention to your shaving direction. While it's true that shaving against the direction of hair growth often yields a closer shave, Dr. Jaliman recommends shaving in the direction of growth to minimize friction and reduce the chance of developing irritation, ingrown hairs or cuts. You'll also want to trim the hair down there before attempting to shave with a razor, Dr. Jaliman adds. "You can use scissors, you can even use an electric trimmer to shorten the longer hairs," she says. But if the hair is long and "all curled up, you won't be able to see which direction it's growing." Once you've trimmed the hair and determined your direction of growth, glide your razor gently along the swimsuit line without adding too much pressure. "One pass should be fine, especially if you're using a razor that has many blades," Ozaki says. Clean your razor when you're done. Blades can easily harbor bacteria, which can lead to infection when used on the skin. Ensure your razor is clean by thoroughly washing it after every use. Focus on rinsing away shaving cream or hairs trapped in the blade, Dr. Jaliman says, and soak the blade in hot water or even rubbing alcohol for good measure. And if your razor looks rusty after you've been using it for a while, toss it. A good rule of thumb is to replace your razor after five to seven shaves, Dr. Engelman says. Calm your skin after shaving. Wash off the remaining shaving cream and loose hairs from your skin once you put your razor down, and hold a cold compress to the area for 10 minutes to prevent irritation and calm inflammation, says Ozaki. "You could even use a little ice" wrapped in paper towel, Dr. Jaliman adds. You can also apply a fragrance-free, anti-redness serum to further reduce your chances of experiencing razor burn, and try topping it all off with a moisturizing body lotion or cream to help prevent shaving-induced dryness. Aim to regularly moisturize the swimsuit line for the first couple days following your shave, Dr. Jaliman says. Similar to your shaving cream, you're going to want to look out for specific ingredients in your moisturizer to ensure it both soothes and hydrates the skin. Bischoff suggests using moisturizers containing aloe vera, as well as jojoba oil and vitamin E. Once your skin is soothed, make sure it stays that way by wearing looser clothes that won't rub up against the swimsuit line, Dr. Jaliman says. Form-fitting clothes can exacerbate irritation from shaving by adding a lot of friction against the skin, she explains. "I wouldn't shave and then go to the gym and put on really tight leggings," she says.2-in-1 Shave Oil & Moisturizer This product can help protect soften skin, and may also be used as an after shave oil for long-lasting moisturization. $6.99 at Moisturizing Body Lotion This lotion is non-greasy, non-comedogenic, and gentle enough for daily use. Consider lathering some on after shaving to avoid dryness. $8.98 at Thermale Avène Xera Calm AD Lipid Replenishing Cream This lotion helps repair the skin barrier and calms itching & visible redness, all issues that can be exacerbated by shaving the swimsuit line. Apply some after removing hair to seal in moisture. $30.60 at Soothe any ingrown hairs and irritation. So, you took your best shot at shaving your swimsuit line, and those itchy, red bumps appeared anyway. Don't worry, there are still many ways you can minimize the discomfort. For one, Dr. Charles recommends looking to that oh-so-soothing aloe vera gel or moisturizer again. Try applying it to the swimsuit line and leaving it there for 30 minutes, she says. This can help reduce any redness, inflammation, and itchiness caused by shaving. If that doesn't do the trick, try using a tea tree oil, Dr. Engelman says. This type of product is an antiseptic and has anti-inflammatory properties, which means it kills bacteria and helps reduce the chances of infection and irritation, she explains. "If you've really caused some irritation, stronger creams like topical steroids, can be prescribed by a doctor to help reduce inflammation as well," Dr. Engelman adds. If you find yourself struggling with ingrown hairs after shaving your swimsuit line, a warm compress could help loosen up the ingrown from your skin, according to the Cleveland Clinic. So could a warm bath with Epsom salt, Dr. Zubritsky adds. Though in general, "ingrown hairs self-resolve and last anywhere from a few days to a week or so," says Dr. Zubritsky. But for those who want to be extra proactive, you can also consider a chemical exfoliator containing alpha hydroxy acids like lactic or glycolic acid to help break down the congested hair follicle, Dr. Charles explains. And acne treatments that target bacteria can also help prevent ingrowns from getting infected, Dr. Jaliman says. Consider using a low-concentration benzoyl peroxide product, for instance. You can find products in concentrations as high as 10 percent, Dr. Jaliman says, but in this case you'll want something closer to 2.5 percent to avoid irritation. Ingrown hairs can often resemble a pimple when inflamed or infected, but resist the urge to 'pick, pull, or pop at your ingrown hair,' Dr. Zubritsky says. 'This may result in permanent scarring or infection.' If you're feeling particularly dexterous, you can also try cleaning the ingrown hair with rubbing alcohol, and then carefully extracting the hair using a sterile, fine-pointed tweezer, Dr. Jaliman says. However, don't attempt to do this yourself if the ingrown looks infected or has grown deeply into the skin, she says. When ingrown hairs are improperly treated or get infected, they can progress into a pocket of pus (called an abscess) or leave behind a scar, Dr. Charles says. So in these cases, it's best to visit a dermatologist for treatment, Dr. Jaliman adds. In the meantime, don't shave again until the irritation has subsided and your ingrown hairs have healed, Dr. Jaliman Duo+M Multi-Target Acne Treatment Salicylic acid can be helpful for treating and preventing future ingrown hairs since it is a beta-hydroxy acid that exfoliates the skin. Apply this treatment to ingrown hairs to help prevent further irritation. $18.74 at Hair Pads With BHA & AHA These single-use exfoliating pads slough away dead skin cells that trap hairs, helping to prevent razor bumps and painful ingrown hairs from forming or getting worse on the swimsuit line. It's formulated with chemical exfoliants such as glycolic and salicylic acids. $20.00 at Acne Treatment This 2.5% benzoyl peroxide acne treatment can kill the bacteria that can lead to an infect ingrown hair. Apply some to any ingrowns on your swimsuit line to nip the risk of infection in the bud. $8.27 at If shaving bothers your skin, consider other options. Look, shaving isn't for everyone. If you still prefer to be smooth down there but want to sidestep all the pitfalls that come with trying to shave your swimsuit line yourself, consider waxing the region instead, Dr. Jaliman says. You can either visit a professional or take advantage of an at-home wax kit. And regardless of your preference, the good news about waxing is that it removes the hair from the root, which means the results last longer, and you're less likely to experience a bacterial infection. And for an even longer-term option for sensitive skin or the shaving-adverse, laser hair removal can negate the need to shave or wax altogether. But if you do decide to wax yourself at home, be careful, Dr. Jaliman says. If done incorrectly, you run the risk of burning yourself or irritating the skin. "I would go to a trained professional," she says. "Somebody who uses clean tools and high-quality wax."

Dermatologist reveals ‘biggest blind spot' people have about skin care: ‘It really is the gold standard in anti-aging'
Is your 10-step skincare regimen all style and no substance? 'I'm always a little surprised at how many people will invest in high-end treatments or complex routines, but skip the fundamentals,' Dr. Dendy Engelman, a board certified dermatologist at Shafer Clinic Fifth Avenue, told The Post. Engelman often sees three glaring skincare slip-ups — including one simple mistake that could be quietly sabotaging your pricey products. Here's how to avoid them. 4 Dr. Dendy Engelman is based in New York City. Tamara Beckwith #1. Retinol regret 'One of the biggest blind spots I see is retinol,' Engelman said. Retinol — the milder, over-the-counter cousin of prescription-strength retinoids — is a vitamin A-derived powerhouse that tackles everything from fine lines to acne. 'It's a cornerstone for increasing cell turnover, smoothing texture, improving pigmentation and stimulating collagen,' Engelman explained. 'It really is the gold standard in anti-aging.' Still, most people aren't using it. Studies show only about a quarter of American women and one in ten US men include retinol in their skincare routines. 'It's one of the most well-studied ingredients we have in dermatology, and yet people are still hesitant, either because they've had one bad experience or because they're worried about irritation,' Engelman said. 'The truth is, there are so many elegant, buffered formulations now that make retinol incredibly accessible, even for sensitive skin,' she added. While retinol can cause irritation like redness, itchiness and peeling, simple steps can help minimize these side effects. 4 Retinol is a common ingredient added to skin creams, lotions and serums. zigres – If you're just starting out, try using retinol every other or every third night and gradually working up to daily use, according to the Cleveland Clinic. Waiting about 30 minutes after washing your face before applying retinol can reduce irritation. For sensitive skin, applying moisturizer first can also help by creating a protective buffer that can prevent discomfort. #2. Exfoliation overload 'People love that fresh, squeaky-clean feeling, but more isn't always better,' Engelman said. Your skin naturally sheds dead cells every 30 days, but when those cells don't fully slough off, it can lead to problems like dryness, clogged pores and hyperpigmentation. Exfoliating — whether with chemicals, scrubs or tools — helps clear the buildup, revealing a brighter, smoother complexion. Over time, exfoliating can even boost the production of collagen, the protein that keeps skin firm, elastic, and wrinkle-free. But going overboard can backfire. 4 Before exfoliating, make sure to wash your face with a gentle cleaner. Svitlana – 'I see a lot of patients with compromised skin barriers because they're using too many acids, too frequently, or layering physical and chemical exfoliants without realizing the cumulative effect,' Engelman said. The result? Inflamed, reactive skin that's more prone to breakouts and dullness. 'Exfoliation should be thoughtful, not aggressive,' Engelman warned. 'It's about supporting the skin, not scrubbing it into submission.' For oily or normal skin, experts generally recommend exfoliating 2-3 times a week. If your skin is dry or sensitive, you may only need to do it once per week. 4 While skipping washing your face one night probably won't cause lasting damage, consistently neglecting this step can harm your skin's health and appearance. Salute Studios – #3. Clueless cleansing In surveys, a staggering 80% of Americans admit to making at least one mistake when cleansing their face — including half of men and women who regularly skip washing before bedtime. 'It sounds so basic, but so many people do a quick once-over with a wipe or skip a proper cleanse altogether if they're tired,' Engelman said. Failing to wash your face, especially if you wear makeup, can lead to clogged pores, breakouts, dullness and premature aging over time. Experts recommend washing your face with a gentle cleanser in the morning and at night to remove sweat, oil, dirt and debris that build up throughout the day and while you're asleep. If you wear makeup or sunscreen, Engelman advises double cleansing at night. 'An oil-based cleanser first, then a gentle second cleanse to remove residue,' she said. 'It helps keep the skin clear, the barrier intact, and preps the skin to actually absorb your serums and treatments. Without that clean canvas, even the best products won't perform.' 'At the end of the day, I'd always rather see someone with a few consistent, thoughtful steps than a long, chaotic list of products that don't work well together,' Engelman said. 'Skin thrives on consistency, not overwhelm.'
