Taylor Swift amplifies sales for 'glitter freckles' business
Sales at Fazit, a beauty company, spiked after Taylor Swift was photographed sporting "glitter freckles" at a Chiefs game.
As temperatures heat up and more Americans are heading to the pool, beach and other outdoor spaces, sun exposure is bound to spike too.
For many people, regardless of skin color, this can mean a rise in visible freckles. But how do you know when a freckle is harmless versus whether it might actually be something of concern to your dermatologist?
Board-certified dermatologist Dr. Hadley King shares all about how to discern between the two, and how you can keep your skin safe this summer.
How long does sunscreen last? A guide to expiration dates, and if waterproof really works
What are freckles?
Freckles, or "ephelides," as dermatologists refer to them, are "pigmented spots that increase in number and darkness with sunlight exposure," King explains.
They're very small (usually less than 3 millimeters) and light brown spots that usually begin appearing on the face, but can also spread outward all over the body, according to the Ohio State Wexner Medical Center. They usually pop up in childhood and become less noticeable as a person ages.
Freckles have an increased amount of melanin, King adds. That melanin is produced by skin cells exposed to ultraviolet light, which is usually more prevalent in the summer. This is why you might notice your freckles fading during the dreary, winter months.
Freckle tattoos are a thing. But read this before you try the viral trend.
What causes freckles?
Freckles aren't directly a sign of skin damage, but people who have more freckles are typically more sensitive to the sun's ultraviolet rays, which can cause skin damage, per Ohio State.
Dermatologists urge everyone, but especially those who are extra-sensitive to the sun, to regularly apply sunscreen and wear other skin coverings when out in the sun. A good rule of thumb is reapplying sunscreen every two hours, and again right after you swim or sweat, according to the American Academy of Dermatology Associates (AAD). You should also get familiar with your skin, and report any changes to your doctor.
Sometimes, new markings that pop up on the body are mistaken for freckles. This can vary from a benign lentigo to a cancerous mole.
Lentigines (the plural for a lentigo) are harmless pigmented spots on the skin that have a "clearly-defined edge, surrounded by normal-appearing skin," King explains. They're sometimes mistaken for freckles, but she notes that this technically isn't correct.
But new spots on the skin can sometimes be cause for concern. The AAD recommends following the ABCDEs of melanoma to help remember what to look out for when doing an at-home skin check:
A is for asymmetry . "One half of the spot is unlike the other half."
. "One half of the spot is unlike the other half." B is for border. The outer edge of the spot is irregular or poorly defined.
The outer edge of the spot is irregular or poorly defined. C is for color . Freckles are a single shade of brown, but ones that are cause for concern can vary with multiple shades of tan, brown, black, red, white or blue.
. Freckles are a single shade of brown, but ones that are cause for concern can vary with multiple shades of tan, brown, black, red, white or blue. D is for diameter. Freckles, as previously mentioned, are small. If a mark on your skin is greater than 6 millimeters (about the size of a pencil eraser), that can be a sign that something isn't right.
Freckles, as previously mentioned, are small. If a mark on your skin is greater than 6 millimeters (about the size of a pencil eraser), that can be a sign that something isn't right. E is for evolving. "The spot looks different from the rest or is changing in size, shape or color."
"Basically, if any spot is new or changing, has any of these features or looks different compared to your other spots, get it checked," King says.

Employers: Use these guidelines to create benefits for the modern workforce
It's impossible to forget the disruption of the COVID-19 pandemic. It reshaped how we live and work, forcing companies to rapidly adapt to remote models and prioritize health and safety in new ways. The crisis made one thing clear for employers: Affordable, meaningful health care benefits are vital — not only for supporting employees but also for ensuring long-term business stability. In the post-pandemic workplace, high-deductible health plans (HDHPs) continue to present challenges, especially for hourly and lower-wage workers. Recruiting and retaining top talent now hinges on offering benefits that go beyond basic coverage — they must be affordable, accessible and relevant. Employers are shifting from cutting costs to investing in benefits that support the whole person. A new framework: Mind, body, money To meet the demands of today's workforce, I use a simple yet powerful framework to guide benefits strategy: Mind, body and money. These three pillars reflect the needs of employees and can help employers design plans that truly make a difference. 1. Mind: Prioritizing mental health Mental health challenges spiked during the pandemic, and they haven't gone away. Today, one in five adults report struggling with mental health, while nearly a third say they don't have a primary care provider (PCP), leading to overall poor well-being. Telehealth has provided a lifeline, but access to in-network mental health providers remains limited. The need for robust mental health support has never been greater, and addressing it must be a priority. 2. Body: Access and prevention Roughly a third of Americans lack a primary care provider (PCP), leading many to rely on urgent care instead. This not only drives up claim volume and employer costs but also increases the risk of chronic conditions going undetected. Consider this: nearly 40% of Americans are pre-diabetic, and managing diabetes can cost $8,000-$10,000 per person annually. For an employer with 50 employees, that could mean $200,000 in preventable expenses. It's critical to ensure employees have access to high-quality preventive care at a price they can afford. Prevention isn't just a health strategy — it's a financial one. 3. Money: Real incentives that work A recent survey by Imagine360 found that 25% of employees would accept a pay cut in exchange for better benefits. That's a powerful signal. But incentives must go beyond surface-level perks like gym memberships. Instead, they should encourage real engagement with health care — rewarding participation in preventive care, screenings and chronic condition management. At the same time, health care costs are climbing fast — especially when it comes to prescriptions. GLP-1 medications are up 200%-300% year over year, prompting employers to reassess pharmacy strategies. Real savings start with aligning incentives to promote smart utilization. The retirement factor Older employees are increasingly delaying retirement — not because they want to, but because they can't afford to stop working. 28% regularly find themselves out of money before payday arrives. 60% of full-time employees are stressed about finances. 56% of financially stressed employees spend three or more hours a week thinking about finances. Consultants must help employers address this early with smart retirement planning tools like 401(k) plans and Health Savings Accounts (HSAs). Financial wellness isn't a separate issue — it's deeply tied to mental and physical health. Supporting employees across all three areas helps ensure smoother, more cost-effective transitions into retirement. Implementing reference-based pricing, a sustainable cost strategy Reference-Based Pricing (RBP) has evolved significantly over the years. What was once viewed as a heavy lift for companies and employees is now gaining momentum as a sustainable solution to out-of-control health care costs, and a great experience for employees. Like HSAs, RBP has continued to garner more adoption — and it's delivering real results. With rising health care 'tariffs,' more employers are turning to RBP to regain control. For example, a nursing home with 800-900 employees implemented RBP and saw health care costs drop by 40%. Four years later, they've maintained those savings, and employees have embraced the model.* RBP is particularly effective for companies with high turnover or low plan engagement. It allows employers to lower deductibles and build a more budget-neutral benefits strategy. While switching any health plan carrier requires change management, the right consultants can guide the process and help ensure both employer and employee success. What consultants must do now It's time for consultants to step up. That means vetting vendors rigorously and recommending only those that align with the employer's core goals — whether it's improving retention, reducing costs or boosting care quality. Employees care deeply about their take-home pay and their health. If a benefit strategy isn't working for them, they'll leave. Strong benefits aren't nice to have — they're a competitive advantage and a critical part of your business strategy.

The 1 Thing That Food Experts Never Eat Or Drink While Traveling Abroad
When you're traveling abroad, you probably have a long list of must-sees and must-dos. Diarrhea, vomiting, and stomach cramps most definitely aren't on that list, but these digestive problems can be all too common. The Centers for Disease Control and Prevention estimates that 30% to 70% of vacationers get traveler's diarrhea, depending on where and when they go. The illness can often (but not always) be prevented by paying close attention to what you eat or drink, and by following the 'boil it, cook it, peel it or forget it' rule. 'Foodborne infections can strike at any time,' Leah Silberman, a registered dietitian with Medical Offices of Manhattan, told HuffPost. 'Traveling exposes you to new food sources, local food handling procedures, and different cleanliness standards. This raises your chances of coming into contact with infections or pollutants, against which your body may not have built protection.' Foods may also be contaminated with unsafe drinking water, or when handwashing isn't the norm or isn't done properly, said Mitzi Baum, CEO of the nonprofit Stop Foodborne Illness. Before traveling, it's a good idea to check the CDC's list of destinations, which highlights food or water safety issues, Baum said. Keep in mind, though, that you can get sick anywhere, including the US. About one in six Americans contract foodborne illness each year, which results in 3,000 deaths and 128,000 hospitalizations, according to the CDC. Travel enhances your risk of getting digestive issues, however. Along with not being acclimated to the foods or encountering different food-handling processes, jet lag and changes in climate can weaken your immune system, Silberman explained. Next time you travel, follow these tips for protecting yourself from traveler's diarrhea. Dietitians and food safety experts explain which foods are more likely to put you at risk for foodborne illness. What Is Traveler's Sickness? Traveler's diarrhea is the most common travel-related illness, and you get it by consuming tainted foods or drinks, according to the CDC. E. coli bacteria is the main culprit, Baum said, but travelers can also get sick from salmonella, shigella, or campylobacter. Viruses, like astrovirus, norovirus, and rotavirus, can also be to blame, as well as the parasite giardia. It often happens in instances of poor food handling, a lack of sanitation, or contaminated drinking water, Silberman said. Diarrhea, abdominal pain, cramping, nausea, vomiting, and fever are the most common symptoms of traveler's diarrhea, according to the Cleveland Clinic. Symptoms of viral or bacterial infections typically show up within six to 24 hours, but parasites can take a few weeks to show signs. The highest-risk destinations are Asia (except for Japan and South Korea), the Middle East, Africa, Mexico, and Central and South America, according to the CDC. Washing your hands frequently with soap and water, especially after using the bathroom and before eating, can reduce your risk, Baum said. Foods And Drinks To Avoid When Traveling Abroad You can actually get foodborne illness from any food or beverage. But some might be riskier than others, depending on where you travel. Food safety measures, sanitary standards, and culinary habits vary in different parts of the world, Silberman said. Your best bet is to research food safety and health risks for your destination. But here are some foods and drinks to consider avoiding. Raw fish and meat Raw meat and seafood are a 'big no-no,' according to Vanessa Rissetto, a registered dietitian and co-founder and CEO of Culina Health. 'We can't source where they came from, how long they've been out, and how they've been handled.' Rare steaks, tartare, sushi, ceviche or raw seafood, or inadequately prepared meat, fish, or seafood can increase your risk for consuming bacteria, parasites, or viruses, Silberman said. Fresh fruits and vegetables Fresh fruits and vegetables that seem to have been sitting out for a while could attract germs that might make you sick, Rissetto said. Opt for cooked produce when you can, which will ensure that it reaches temperatures high enough to kill pathogens. 'If you're going to eat fresh fruits and vegetables, they are safest when washed with potable water and peeled by the person who eats them,' Baum added. Also, choose fruits and vegetables with thick skins — like bananas, oranges or avocados — that can be peeled, Silberman said. 'Peel them yourself to reduce the possibility of eating pathogens.' Dairy Pasteurized milk and dairy products from sealed containers are usually safe to consume, according to the CDC. But unpasteurized items, including cheese, yogurt, or ice cream, are more likely to contain hazardous germs, like listeria, salmonella, or E. coli, Silberman said. It's also a good idea to avoid dairy that's been stored at room temperature or left out, such as cream for coffee. Tap water Alberto Masnovo / Getty Images Contaminated water is a big cause of traveler's diarrhea. 'Since pathogens aren't visible to the naked eye, it's hard to tell if the water is safe to drink,' Baum said. To learn about the safety of tap water in your destination, visit the CDC's travelers' health website, where you can search by country. Whenever you're not sure about the safety of water, drink factory-sealed bottled water and remove ice from your drinks, Baum said. You can also boil water for at least a minute. Be careful not to swallow any water in the shower if you're visiting a place where the water isn't safe to drink, and use bottled water to brush your teeth, Rissetto said. Certain types of street food DigiPub / Getty Images Sampling food from street vendors is a fun way to sample local cuisine, but the CDC warns that some may not adhere to the same safety practices — like hand-washing and checking food temperatures — as restaurants. It's always best to avoid foods and drinks that seem to be sitting around for a while. Items that come straight off a grill, for instance, that are piping hot and cooked are likely safer. What If You Get Sick While Traveling? If, despite your best efforts, you do get a case of traveler's diarrhea, it's usually not serious. But it can persist for a few days or a week (longer if it's caused by a parasite), ruining your trip. Silberman offered these tips for taking care of yourself if that happens: Stay hydrated. Diarrhea and vomiting can be dehydrating, so drink lots of bottled water or other safe fluids. Take an over-the-counter medication. Antidiarrheals, like loperamide (Imodium), or anti-nausea drugs, like dimenhydrinate (Dramamine), help relieve symptoms. Talk to a healthcare expert first, though, especially if you're taking other medications. See a doctor. If your symptoms aren't going away, they're severe, or you also have a fever, bloody stool, or dehydration, seek medical attention. Call your doctor when you get home if you still have symptoms or if you have an underlying medical condition. No one wants to get sick while traveling, of course. But remember that foodborne illness can happen anywhere, Rissetto noted. 'If we go on vacation overly worried about every single thing we're eating, we might not be able to truly enjoy the experience,' she said. 'You can determine what's right for you in the moment.'

Collins calls Kennedy's firing of vaccine experts ‘excessive'
Sen. Susan Collins (R-Maine) on Monday called Health and Human Services Secretary Robert F. Kennedy Jr.'s firing of all 17 experts on the U.S. Centers for Disease Control and Prevention's (CDC) vaccine panel 'excessive,' but she cautioned she needs to learn more about the decision. Kennedy announced the decision in an op-ed for The Wall Street Journal, catching many GOP lawmakers by surprise. 'I did not know that that had happened,' Collins, a senior member of the Senate Health, Education, Labor and Pensions (HELP) Committee, said. 'It seems to me to be excessive to ask for everybody's resignations, but I can't judge because I don't know who he's replacing them with.' The Maine senator said the CDC's vaccine advisory committee 'provided helpful guidance to the public on what they should do.' Collins said that Kennedy didn't promise members of the HELP Committee that he would keep the vaccine experts in place. 'I'm just learning about it for the first time,' she said. 'I don't know what the basis was.' Kennedy said in his Wall Street Journal column that he removed the experts so that President Trump could shape the membership of the committee. 'Without removing the current members, the current Trump administration would not have been able to appoint a majority of new members until 2028,' he wrote. Kennedy argued that vaccines have become 'a divisive issue in American politics' and that public confidence is waning' in health agencies, pharmaceutical companies and vaccines themselves. 'That is why, under my direction, the U.S. Department of Health and Human Services is putting the restoration of public trust above any pro- or antivaccine agenda. The public must know that unbiased science guides the recommendations from our health agencies. This will ensure the American people receive the safest vaccines possible,' he wrote. Senate Democratic Leader Chuck Schumer (N.Y.) in a statement blasted Kennedy's move as 'reckless.' 'RFK Jr. and the Trump administration are taking a wrecking ball to the programs that keep Americans safe and healthy. Firing experts that have spent their entire lives protecting kids from deadly disease is not reform — it's reckless, radical, and rooted in conspiracy, not science,' Schumer said in a statement.
