COSRX Snail Mucin skincare review: I tried 5 products from the K-beauty brand
It's been praised all over social media for its super-hydrating properties, so I knew I had to review COSRX snail mucin to see the results for myself.
COSRX Snail Mucin Skincare at Lookfantastic
When I visited Seoul last year, I was struck by the fact that the brand's bestselling products champion one key ingredient: snail mucin.
'It's a nutrient-rich byproduct compatible with all skin types that can help improve a damaged skin barrier by offering deep hydration,' says Julia Marinkovich, the UK COSRX representative.
'This can help contribute to a plumper and more glowing complexion, and there's also research to support the claim that snail secretion filtrate can promote wound healing and improve the appearance of fine lines and wrinkles.'
With this in mind, I decided to test the five most popular snail mucin products from the K-beauty brand, including the hero Snail 96 Mucin Power Essence, to see if I could heal my dry and sensitive skin.
So read on to find out what happened when I tested COSRX.
Pros
Intensely moisturising
Non-irritating
Repairs the skin's barrier
Cons
Not suitable for shellfish allergy
Not vegan
Sticky texture
Overall Rating: 4/5
How I tested COSRX Snail Mucin Skincare
I have combination skin that's on the drier side with an oily T-zone.
My skin has also become sensitised over the years due to over-exfoliation and testing out hundreds of beauty products.
I swapped my current skincare essentials with five COSRX products and tested them for over a month, every morning and night.
As I didn't try out a cleanser or SPF from the brand, I used existing products in conjunction with the tested products.
COSRX Snail Mucin Skincare review: Quickfire Q&A
How much is COSRX? The cheapest item in the COSRX range is the £5.99 COSRX Acne Pimple Master Patches. The most expensive item is the COSRX Full Fit Propolis Light Ampoule serum, which costs £33.99.
Who's it best for? While suitable for all skin types, the range is particularly good for anyone with a damaged skin barrier who wants to restore their complexion.
What we loved: I immediately felt a difference using a number of the products. My skin instantly felt hydrated and moisturised for longer thanks to innovative ingredients that really work. Affordability is another positive.
What we didn't: Whilst the products work really well together, those who like to mix-and-match brands may find that thicker formulas don't sit as well on top of certain products in the range.
COSRX Snail Mucin Skincare review: The Nitty Gritty
Advanced Snail 96 Mucin Power Essence
BUY HERE
Spoiler alert: Snail 96 Power Essence is well worth the hype.
While it's labelled as an essence, I think it's better to categorise this as a serum as its viscous texture is similar to Hyaluronic Acid serums, but is less watery in texture, which makes applying it much easier.
The trick to getting the most hydration out of it is to apply it on damp skin, so after cleansing, I spritz a facial spray over my face and wait a few seconds before applying the essence.
A little goes a long way; you only need one to two pumps to cover the entire face.
It's got a super-high concentration of snail mucin, and I've noticed almost immediate effects since using this; my skin feels instantly hydrated and stays moisturised for longer throughout the day.
Moreover, I'm impressed with how it's managed to soothe my skin's barrier and even take down some redness I have.
Personally, I prefer using this over Hyaluronic Acid as it keeps my skin hydrated for longer, and the texture works for my dry skin.
However, oilier skin types may find it too heavy, and I used less on my forehead than on my cheeks.
It does take a bit of work to figure out how to layer it.
While it worked perfectly with its snail cream and light moisturisers, it didn't absorb as well when I layered an E45 face cream over it, as it was too occlusive.
But it's been over a month since I started using this essence, and it's become part of my daily routine, and when I finish this bottle, I'm immediately getting another one.
Advanced Snail 92 All-in-One Cream
COSRX Advanced Snail 92 All-in-One Cream, £30.99 from Lookfantastic
BUY HERE
Pros: Gives a glowy finish, hydrating, soothes dryness and redness, works under make-up
Cons: Sticky texture, not moisturising enough for dry skin, messy application
Rating: 3.5 / 5
If you want glass skin immediately, then the all-in-one snail cream will deliver just that.
Similar to the essence, this cream is infused with a whopping 92% of snail mucin, and when you open the jar, it looks exactly like slime.
I didn't mind the look of it too much, but I did find that it's a bit messy to use.
It's super sticky to the touch, which makes it tricky to extract the right amount, so you'll want to start small and then apply more if needed.
But it's amazing value for money, as only a small amount is needed to cover your entire face.
Surprisingly, when I massaged it on, it didn't feel greasy at all and left my skin with a glossy sheen, almost filter-like, and I absolutely loved the look it gave.
It also works well under make-up, but make sure you layer it with more cream-based products, as opposed to powder, to emphasise the glow.
Despite the glowy look, I actually found that it wasn't moisturising enough to keep my dry skin hydrated for long periods, and I had to apply an emollient cream over the drier parts of my face.
I've since moved this to my nighttime routine as it's slightly too fussy for me to use in the daytime, and I prefer using a richer cream to really lock in that moisture.
mouth and eye area and press the remaining residue in with fingers.
COSRX Master Pimple Patch
BUY HERE
Even though COSRX is known primarily for its snail mucin products, its pimple patches are one of its bestsellers.
Having used these patches in the past, I was excited to test out a fresh pack of them as I loved them so much on my first go.
Happily, these didn't disappoint. They were great for targeting spots and have a transparent look, so they look invisible on.
They're also comfortable to wear, and I liked wearing the stickers to bed or when I would be working from home.
They are a bit fiddly at first as you can only apply them onto dry skin, so it's best to wait until after your skincare products have been absorbed before putting them on.
My partner has acne-prone skin and enjoys using the pimple patches as they help prevent dirt from touching the spot and allow the skin to properly heal.
The patches were effective in reducing any redness and excess oil and definitely minimised the appearance of spots.
Plus, you can get up to 90 in a pack, which is excellent value for money.
Size: 36-90 pack Skin type: All How to Apply: Apply gently with the sticky side down. Leave on overnight.
AHA / BHA Exfoliating Facial Treatment
AHA / BHA Clarifying Treatment Toner, £21.99 from Lookfantastic
BUY HERE
Having over-exfoliated my skin in the past, I was a bit hesitant about using this COSRX treatment.
The AHA/BHA Clarifying Treatment Toner is an exfoliator wth an ingredient list that includes 0.1% glycolic acid (AHA) and 0.1% Betatine Salicylate (BHA), but since it's got a low concentration of both acids, it's gentle to use even on sensitive skin.
I was surprised to discover that it didn't irritate my skin and actually helped to clear my blackheads, particularly on my nose.
Over time, it helped to slough away dead skin cells, leaving my skin more radiant, and when I layered the essence or an active ingredient on top of it, it didn't sting.
The instructions state that you should spray the exfoliator on a cotton pad and then swipe the pad across the face.
However, I found it easier to spray the product directly onto my face as the cotton pad wasted a lot of product, and I could target the exfoliator on areas of my face that needed it more, like my T-zone.
While you could use it every day, I prefer to use it once or twice a week, as I don't suffer from active breakouts, so that's why it became my least-used product of the ones I tested.
But if my skin breaks out, this will be the first product I'll be reaching for.
Retinol 0.5% Oil
COSRX Retinol 0.5 Oil, £29.99
BUY HERE
I love using the COSRX retinol in my skincare routine as its anti-inflammatory properties really benefit my skin.
In the Cosrx product, there is quite a low concentration of retinol, making it best for beginners as opposed to regular retinol users or those looking for a low dosage, but I love its formula.
More similar to an oil, it feels nourishing thanks to the blend of Vitamin E and Squalane, and it didn't dry my skin out.
It also pairs well when layered over the essence and under both thicker and lighter moisturisers.
It has an earthy scent which isn't too pleasant, but it does dissipate.
It's too early to truly tell the difference, as you need at least three to six months to see whether it's made a real impact, but I've had fewer blemishes and redness since using it without having to go through purging.
Oiler skin types may prefer a retinol cream, but I now use this every evening as I love how soothing it feels.
After using COSRX for over a month, I'm a snail mucin convert. I've really noticed that both the essence and the cream helped to soothe a lot of redness that I experience from dry weather and also keep my skin hydrated.
Not to mention, it creates a glass-skin-like effect on your face that's pretty perfect for glowy skin lovers.
While it's not vegan, COSRX is cruelty-free, and a good option if you've been let down or have suffered from sensitivities to Hyaluronic Acid.
Most of the products I tried from COSRX are geared towards drier skin, but I believe every skin type can benefit from them.
Particular highlights for me were the Advanced Snail Mucin Essence and the retinol; those two are going to become staples in my skincare routine.
What is snail mucin and is it good for the skin?
It might sound like something out of a horror film, but snail mucin (aka snail slime) is the gooey stuff snails naturally secrete to protect themselves.
In skincare, it's filtered, purified, and packed into serums and creams thanks to its barrier-boosting and glow-enhancing properties.
Whether you're dry, oily or somewhere in between, snail mucin can boost moisture, repair damage and leave your skin looking bouncier than ever before.
It's gentle too, so even sensitive types can get in on the action.
What are the benefits of snail mucin?
Snail mucin is rich in hyaluronic acid, glycolic acid, peptides and antioxidants, meaning it helps plump the skin, fade acne scars, smooth texture and calm inflammation.
Hydration, healing, glow: it does the lot. Think of it as your skin's new overachieving best friend.
It is best to apply snail mucin after cleansing and toning, but before your heavier creams or oils.
Pat a few drops into damp skin, let it soak in, then carry on with your routine.
Use morning or night, or both if you're feeling fancy.
Is snail mucin good for acne?
Snail mucin is GREAT for acne. It helps calm redness, fade leftover marks and keep your moisture barrier strong (which is key when dealing with breakouts).
It won't clear your spots overnight, but it's a solid add-on in your anti-acne arsenal.
Is Cosrx cruelty-free?
Yes! Despite the snail connection, Cosrx does not test on animals, and the mucin is collected from happy, stress-free snails in a lab, with no squishing involved.
Where can I buy COSRX in the UK?
Originally from South Korea, COSRX is now available globally, with plenty of beauty retailers stocking it in the UK.

US records more cases of Chikungunya virus
Cases of the debilitating chikungunya virus sweeping through China are also surging in the US, health officials have warned. CDC officials have reported four more cases this week, bringing the total to 50 cases of chikungunya in the US, all of which are in people who traveled to areas where it is more common like Asia and South America. It is unclear how many are linked to China's outbreak. The virus, which is spread by the Aedes mosquito, can cause sudden, agonizing joint pain in the hands and feet that can be so severe that it leaves sufferers unable to move normally for months. Chikungunya is tearing through China with more than 10,000 cases, leaving the nation battling its largest outbreak ever. The outbreak has prompted the CDC to issue a level 2 travel warning for China, which urges Americans to take extra precautions when visiting the area. The notice also applies to Brazil, Colombia, India, Mexico, Nigeria, Pakistan, the Philippines and Thailand. Chikungunya is a 'nationally notifiable' condition in the US, meaning health authorities can voluntarily report cases to the agency for national tracking and monitoring. While a handful of cases pop up in the US every year from people traveling to high-risk areas, it hasn't experienced local transmission since 2019. But with 1.6million people traveling between the US and China every year, mosquitoes in America could bite an infected traveler and begin transmitting the virus locally to Americans. Dr Louisa Messenger, a mosquito researcher in Nevada , previously told : 'This outbreak in China is very concerning. It [the virus] could already be here in the US; and really it's just one plane flight away.' Along with the CDC, travel agencies and cruise lines have also issued warnings about preventing mosquito-borne diseases, including chikungunya, dengue and Lyme disease, all of which have been detected in the US so far this year. Chikungunya is spread to humans from a bite from the Aedes mosquito, which also spread dengue fever, yellow fever and Zika virus. The infection does not spread from person to person through bodily contact or saliva. However, pregnant women who become infected near the time of delivery can pass the virus to their baby during birth, which can result in severe illness in the newborn. About 15 to 35 percent of people infected with the virus are asymptomatic, the CDC reports. The incubation period is typically three to seven days and the most common symptom is a sudden onset of a fever over 102 degrees Fahrenheit (39 degrees Celsius). Other symptoms of chikungunya virus include headache, nausea, rash, muscle aches, swelling and redness of the conjunctiva (the white part of the eye and inner eyelids) and joint pain that is sometimes severe and debilitating in the hands or feet. In severe cases, life-threatening complications involving the heart and brain can occur such as inflammation, irregular heartbeats and organ failure. Symptoms usually last seven to 10 days, but patients may experience lifelong complications such as persistent joint pain. There is no specific treatment for chikungunya, and doctors mostly focus on easing symptoms like over-the-counter pain and fever medications. However, there are two vaccines available for people visiting an area with an outbreak.

New study finally busts health myth of much-loved tropical fruit
Two new clinical trials have countered conventional dietary wisdom by revealing that eating mango instead of carbohydrates like bread can improve blood sugar levels for type 2 diabetes. Around 830 million people have diabetes across the world, the World Health Organisation has said, with 90 per cent diagnosed with type 2 diabetes, meaning the body has become resistant or doesn't produce enough insulin. In India, this amounts to an estimated 77 million adults, while another 25 million are prediabetic. Speaking to the BBC, one Mumbai -based diabetologist said he frequently gets asked if patients can eat mangoes, a fruit that is central to Indian life. "Mangoes, with their rich sweetness and diverse varieties, are a staple of Indian summers, and it's understandable why people want to indulge," says Rahul Baxi. However, there are a number of misconceptions with some believing mangoes should be strictly avoided, while others think the fruit might 'reverse diabetes'. A pilot study involving 95 participants found that three Indian mango varieties, the Safeda, Dasheri and Langra, produced similar or lower glycemic responses than white bread over two hours of glucose testing. A glycemic response refers to how a food or meal affects your blood sugar (glucose) levels after you eat it. Over a period of three days, continuous monitoring of people with and without type 2 diabetes found that post-meal sugar fluctuations were significantly smaller when swapping bread for a mango. Experts say this could be beneficial to the body, with Dr Sugandha Keha, the author of both studies, stating: "These studies show that within prescribed diets, consumption of mangoes are not detrimental to blood glucose and may even be beneficial." A second week trial reinforced these findings, finding that the 35 adults with type 2 diabetes who replaced bread with 250g of mango showed improvements in their insulin resistance, fasting glucose, weight and waist circumference among other positive outcomes. "We showed the benefits of small doses of mangoes in place of carbohydrates (bread) in breakfast in two detailed studies for the first time, laying to rest all speculations regarding adverse metabolic effects of its consumption," says Prof Anoop Misra, senior author and study lead. "But the key is moderation and clinical supervision - this is not a licence for unlimited mango feasts." In India, mangoes occupy cultural, social and even diplomatic influence and are a feature of everyday life. There are over 1,000 varieties grown across the country, while baskets of mangoes are often given to visiting dignitaries as a sign of welcome and respect. In terms of moderation, it is advised that any mango should be part of a person's daily limit of calories. "If your daily limit is 1,600 calories, any calories from mango should be part of that total, not extra. A 250g mango - about one small fruit - has roughly 180 calories. As in the study, you'd replace an equivalent amount of carbs with mango to get the same results," Professor Misra said.

The pioneering therapy that could roll back the rigours of ageing
The clock could be turned back on ageing with a groundbreaking new therapy that aims to recharge cells with 'batteries' from the placenta of newborns. Israel-based Minovia Therapeutics is the first company in the world to start testing mitochondrial transplantation in humans, which could treat incurable diseases and keep bodies younger for longer. Mitochondria are tiny compartments within cells that act like batteries, supplying the cell with the energy it needs to function. In ageing and certain diseases, the mitochondria stop working efficiently, starving the cells of energy, similar to the batteries running down in a machine. But scientists have now shown that it is possible to 'augment' cells with supercharged mitochondria from the placenta. Minovia has already completed clinical trials of the new therapy for patients with Pearson's Syndrome - a mitochondrial disease - and is planning to trial the treatment in elderly people next year. Dr Natalie Yivgi-Ohana, CEO and co-founder of Minovia, said: 'It's actually a very natural process for cells to take up mitochondria when they come in contact with them, but it was usually only one in 1000 cells that would do it. 'In the past 13 years, we've developed a method to maximise cellular take up without harming the cells or the mitochondria, so now more than 50 per cent of cells take up a significant amount of mitochondria. 'We take it from the youngest and healthiest organ, which is the placenta and which is full of super mitochondria and yet it's normally thrown away like garbage. We could find it to be the fountain of youth.' To make the therapy, scientists take the mitochondria from a healthy donated placenta and mix them with blood stem cells, which are then infused back into the patient's bloodstream. Not only do the super mitochondria help to produce more energy in cells, but they also reactivate natural quality control functions inside cells, which keep failing mitochondria at bay. So over time, the level of the body's healthy mitochondria also goes up. Last month, the company released phase 2 results for Pearson Syndrome, which can cause a range of problems in children, including failure to thrive, diabetes and neurological issues. There are currently no approved therapies for the condition, and care is only palliative, with patients dying during childhood. But the new therapy has led to marked improvements. 'Severe energy failure' 'These were all paediatric patients and they suffer severe energy failure, so they are not growing,' added Dr Yivgi-Ohana. 'It took a few months, but we have started observing improvement in their energy and less fatigue, more waking hours. We observed improvement in renal function, improvement in appetite, in growth.' Now the company is turning its attention towards ageing, and is hoping that growing older may one day be seen as a treatable disease. The company is planning to start trials of the treatment for elderly people in Israel next year and is developing biomarkers so they can test whether older people are experiencing mitochondrial dysfunction. It could even help diseases of ageing, such as Parkinson's, which is strongly linked to mitochondrial dysfunction. 'Significant in almost every disease' 'We are all going to suffer mitochondrial disease as we age,' added Dr Yivgi-Ohana. 'Ageing is not considered a disease, but if we have a way to demonstrate that actually, as we age, we become mitochondrially dysfunctional, then that would be the trigger to propose a treatment. 'We want to start next year treating elderly people with mitochondrial dysfunction in longevity clinics and demonstrate that it really helps. ' She added: 'The scalability in terms of the mitochondria is unlimited, there are no limitations of placentas and the amount of mitochondria that we can harvest and cryopreserve.' 'Mitochondria are such powerful organelles, and they can transfer between cells, so their sensing and their information transfer is so significant in almost every disease that you will look at.'
