COSRX earns strong reviews as an effective, no‑frills skincare brand, with standouts like Advanced Snail 96 Mucin Power Essence, Acne Pimple Master Patch, and Full Fit Propolis Synergy Toner delivering hydration, calming, and visible acne relief. Reviews also note drawbacks: certain formulas feel sticky or slimy, can trigger breakouts or irritation on sensitive or dry skin, and some cleansers and exfoliants underperform or feel stripping.

  • This eye cream is super lightweight but so hydrating — perfect for my under-eye area. The snail mucin and peptides help smooth fine lines and brighten dark circles over time. It’s gentle, effective, and works beautifully under makeup too. 🐌✨

  • This toner-like treatment helped me reduce skin texture without causing irritation, which is perfect for my sensitive skin. It’s extremely lightweight—almost watery—which can be tricky to apply, but it leaves my skin calm, soft, and balanced.

  • ده من المنتجات اللي دايمًا برجع أشتريها تاني 🔁. فعّال جدًا في تقليل الرؤوس السودا وتنظيف المسام، خصوصًا لو استخدمتيه باستمرار مرة أو مرتين في الأسبوع 🧼. بس لو بشرتك حساسة، ممكن تحسي بوخز بسيط في البداية، فابدئي بكمية قليلة وببطء 🧪

  • Toner is very hydrating and soothing, perfect for dry and sensitive skin. Some users noticed changes in scent and texture recently, which caused irritation for a few. If you’re sensitive, alternatives like Isntree Hyaluronic Acid Toner might be better. 💛

  • This lip mask is thick, buttery, and deeply hydrating—perfect for overnight repair. I wake up with smooth, soft lips and no flakiness. It’s a must if your lips get dry or cracked easily! So cute and highly recommended 🌸

  • This serum is a game-changer if you’re looking to smooth skin texture and control oil. It hydrates deeply, helps even out skin tone, and makes pores look tighter over time. Super lightweight and layers well with other products!

  • I didn’t expect to fall for a snail cream, but here we are. This COSRX All In One is that girl. It’s lightweight but deeply hydrating, leaves my skin bouncy and calm, and just… healthy. No sticky mess, no fake promises—just real, dewy results. A staple in my routine now. 🐌✨

  • Really really love COSRX’s products! For instance, their snail mucin is such a perfect hydrating serum for me, and I loved their every day cleanser- it really worked well on my skin, effective but not too stripping!

  • Something I can’t believe about this brand is how affordable their products are for how innovative and effective the formulas are. They have really gentle soothing products but also potent actives that will really give you results. The peptide booster serum is really lightweight and watery, so it can really soak into your skin before you put on heavier products.

  • Love this brand. The hype is legit. The Advanced Snail 96 Mucin Power Essence is beyond hydrating. It is a part of my morning and night routine. This was my first snail mucin product and I was both curious and hesitant to use it. I know that trying K beauty can be something that's intimidating when you've never tried it before. CosRx is definitely worth giving it a try. I have yet to find a product made by them that I don't like. If you want to add some innovative products to your skincare routine, I don't think you can go wrong with CosRx.

  • ADVANCED SNAIL 96 MUCIN POWER ESSENCE 100/10 I have been struggling with acne since I was 12 I am 22 now.. this stuff CLEARED my skin I use it like 4 times a day and I’ve gone through 4 bottles already

  • When I first heard about COSRX, I was intrigued but thought it was just the latest fad or trend that wasn’t going to last. Finally I gave in and purchased the all in one cream. After getting over the fact it was very slimey and goopy, I gave the product a real go. Now I love it, I’ve just purchased the retinol 0.5 oil, which I will be testing soon. The gel is very good for my skin , it makes it tacky for a while but it does take it in and absorb it. My skin is hydrated and very nourished with this a part of my routine. This is a Korean brand I believe, in which again, I have not really had much experience with. If you haven’t tried COSRX yet, I would recommend starting with the all in one cream like I have done. You can use it when you want , morning or night up to you. I’m hoping I will be impressed with my latest purchase with COSRX

  • I LOVE THIS !!! I own the toner and snail essence and my skin has never felt better. Both products works amazing on my skin and I definitely see huge differences as I get a more moisturized and hydrated face. Also the products are very lightweight

  • I personally did not see many benefits to the snail mucin. It felt nice on my skin but it never felt super hydrating or hydrated any wrinkles. For how popular this is I was expecting more, I don’t planning on buying it again .

  • I was uneasy about this at first because of the whole snail mucus aspect, but after using COSRX Snail Mucin 96% Power Repairing Essence I am beyond impressed. It really does hydrate skin super well and I have seen improvements in my skin too. Only downside can be the price, but the results make it definitely worth the money.

  • I purchased the Cosrx Advanced Snail 98 Mucin product, and I have to say it's impressive. After just a few days of application, I noticed my skin became firmer and more even in tone, with a noticeable radiance. The amount of product is also amazing—I haven't even used up half of it, and I've been using it for six months.

  • I purchased the COSRX Snail 96 Mucin Power Essence, even though I heard mixed reviews. Some people said it made them break out. Luckily, that didn't happen with my skin, I was able to test this product before purchasing it. I was visiting my sister and she had the product in her skincare lineup. I used it every day and I loved how it made my skin feel and look. I apply it to damp skin and use it after my serums but before my moisturizer. Hopefully, I will get to try more products from this brand n the future.

  • I simply love their products. I was looking for something to keep my skin healthy, glowing and moisturize and that keeps the moisture locked in. And ever since I started using the snail mucin I have been loving it. Game changer. I got the small one to try out and when I went back I always only see the small one and so I just buy couple it. It’s worth the hype.

  • Absolutely love! Just began using it and I’m seeing results! Feels amazing, non irritating! The pricing is phenomenal! My skin feels so soft! This is my current fav

  • First of all I got hemmed up watching tiktok reviews and honestly SMH but I was so curious I just had to...first week in as I passed a mirror and said oh sh!t I think I see something happening. I never look in the mirror because my skin is terrible so why keep looking at it and have tried everything on the planet nothing helps. Well let me tell you this is the real deal. I'm at the end of the two week mark and I'm in total WTF. The difference is a real, what am I looking at. I can't wait until more time has gone by. We're talking year's of dark deep hyperpigmentation, still there but it's definitely getting better. Two days ago I ordered their niacinamide to add to my regimen. All the talk is true and I mean that. The pricing is so fair that you're almost forced to just give it a try.
