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.

  • 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.

  • Oh this spf is my all time favourite! Light, smoothing, watery texture, easy to apply. It doesn’t leave my skin greasy and no white shade 💪

  • I was tired of constantly fighting my skin and embarked on a journey to get the clear youthful skin I deserved. I was pleased to find that the skin of my dreams in a Korean beauty inspired routine. The best part is that nearly all the products I tried were relatively inexpensive and readily available from amazon. My acne is non-existent now and the tone and texture of my skin is so supple and smooth. I have provided a list of my routine below which includes this product. I’m not saying this is the best or only way to achieve my results, I just thought others would be interested in what I used.

  • I really love their snail mucin. It really soothes my combination skin. It gave me a dewy look which I also loved.

  • I’ve been using the COSRX Advanced Snail 96 Mucin Power Essence for a little around half a year now and it’s great! Having dry acne prone dehydrated skin, I regularly get inflamed blemishes and flakes and this essence has really helped with not only calming my skin down, but with my dry flakes especially during the winter. I use it night after cleansing, toning and applying my hyaulronic acid to lock it in, I follow up with my moisturizer to occlude everything in and wake up with glowy hydrated skin! Definitely one of the best products COSRX has and will be repurchasing for sure.

  • Love their products very simple and the face wash makes your skin feels so refreshing and soft.

  • I've used a few products from COSRX in the past years & nothing really stuck... I appreciate the formulations but I never really saw the results I was looking for!

  • COSRX offers effective, affordable skincare with clean ingredients and a focus on results. I’ve seen real improvements in texture and breakouts, especially with their snail mucin and exfoliating products. Some formulas can be a bit sticky or take time to show results, and not every product works for every skin type. Still, it's a solid, dependable brand with great value and thoughtfully formulated options.

  • I tried the snail mucin essence moisturizer and liked it. But now that only use vegan and cruelty free products, I wouldn’t get this again.

  • Love COSRX. I always repurchase their pimple patches and also the Advanced Snail 96 Mucin Power Essence. These two products are an 'always go back to and can trust'. The pimple patches (specifically the oval-shaped 'Master Patches') truly work, and the snail mucin always calms my skin down and leaves it feeling plump. Highly recommend these two! I've also tried the Low PH Good Morning Gel Cleanser, however found it to be a little too stripping for my skin. I'd love to try out their Propolis range. 🐝

  • The Snail Mucin is amazing, I love it.

  • Tried this brand and it didn’t really work for my skin. Not saying people shouldn’t try it or that it’s bad, it just wasn’t for me.

  • I tried the viral snail mucin and It was great at first but broke out my skin short after, I do have sensitive skin! it may work for you but this is just how it worked for me. definitely an inexpensive brand for how high quality it is.

  • I think most people start with the snail serum as an easy intro to Asian beauty products. I think it’s a fantastic product for most skin types and leaves you feeling moisturized and fresh

  • A truly impressive brand. Their ampoules (supercharged serums) are so effective on breakouts and I love their pimple patches - just my favorite of all the ones I've tried. Their moisture cream and snail mucin did not agree with my skin, but I am nevertheless impressed by their products.

  • One of my favorite skincare brand, you have to try their Advanced Snail Essence, it's so good and work so well on my skin.

  • I LOVE their acne pathces they are wonderful and so convenient. I've also tried their BHA tonerwhich although the ingredients are clean, I did not find to be as effective as other brands. I went back to Good Molecules and Paula's Choice for my BHA toner. I find they have a good product line and will be trying out more of their products.

  • I am a huge fan of Korean skincare and have tried several ton of brands. COSRX is popular because they are reliable and make good, noj irritating products. I like their moisturizers but have found their toners to not really make a noticeable difference.
