  • Hydrating snail mucin essence
  • Effective acne-healing patches

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.

  • Amazing pimple patches! My favorite brand for these because they are so thin I forget they are on my face. Work very well too.

  • I have tried their viral snail mucin products that personally I find only OKAY for some reason, pretty sticky and not as moisturizing as I expected (I have dry, mildly sensitive skin). I find that their propolis products work better!

  • I love love love CosRx. I've been using the low pH cleanser since 2016 so for about 7 years now. It's cheap and accessible almost in every beauty store and I love the way it makes my skin feel.

    I think it's a great product: no gimmicks or frills and gets the job done.

  • I am currently using the Corsx Hylauronic Essence and Hylauronic Moisturizer. I have sensitive, combination skin and struggle with breakouts. In the winter, my skin leans towards dry. The essence is not too sticky and feels very smooth on the skin. If my face is not completely dry before applying it, the essence tends to foam a bit while rubbing it in, but it doesn't affect the absorption. The moisturizer is very lightweight yet still hydrating, something I have struggled to find in a gel formula. It doesn't pill and works as a great base for makeup. I love the consistency and I am on my second bottle already! I have just started using the Low PH Cleanser, so it is too early to review that. Overall the brand is quite affordable and of great quality. I am excited to try more of their products.

  • I LOVE COSRX. I’ve been using their snail mucin for months, and my skin has never felt better. I appreciate that they sell different sizes, but I always get the big one because I know I’ll always love it and use it every day.

  • I love it because of the great quality of its products. Every time I try something from this brand it surprises me more. I recommend the Snail Mucin range as it left my skin super soft and got rid of my acne marks. Besides, the Niacinamide 15 serum is super good.

  • Snail mucin essence & snail 92 cream are the real deal! The only advice I have is don’t use it everyday. After only 2 weeks I’ve noticed tremendous results in faint fine lines becoming almost nonexistent & acne scars slightly faded.

  • Every product I have tried I have loved. It's a great brand for every skin type and concerns. I love the BHA/AHA spray, it has made my skin less dull and feels refreshed.

  • Bought the COSRX Snail 96 Mucin Power Essence in the Amazon Prime Day sale and GIRL! It's pretty good and I feel like my skin is so much more glowy after using it! I haven't been breaking out with it at all, but I've been using it for about 2 weeks and I feel like it hasn't made the biggest long-term difference in my skin. Maybe time will tell!

  • I've only used the COSRX Acne Pimple Master Patch a few times so far and I do feel like they seem to work quite well. Each time the pimple has reduced quite a bit and depending on how long i've left it on, the whitehead has 'softened' and is removed together with taking off the patch or has gone entirely. Since my acne has been getting a bit worse, i'm planning on testing the AC Collection Acne Patch and their AC Collection Lightweight Soothing Moisturizer (will be updating this review after that :) )

  • I absolutely love my snail mucin from COSRX. My skin has been so much brighter and softer. Will definitely buy again!!

    Verified purchase

  • Tried one of their viral products on TikTok and have been using it consistently since! The brand is great I got the Snail Musclin product and it has worked wonders on my skin.

  • one of my favorite Korean skincare brands, I love that they are no frills with trustworthy ingredients. I will always continue purchasing from them!

  • Just started using their snail essence! No break outs from it so far and it feels amazing. Kept my skin from getting dry on the plane.

  • Enjoyed the low ph cleanser - it smells good and feels light and clean. However, I think other products were eventually more effective for me in the long run but I didn't have any breakouts from using the product for several months!

  • Good price point and high quality ingredients. Doesn’t really stand out but definitely gets the job done.

  • I’ve used various products from them over the past few years, including their snail mucin serum, propolis serum, pimple patches, and BHA toner spray

    Feedback

    Overall, a great value and quality. Bc it’s a more accessible price point, this is a great option if you’re trying to try new ingredients to see how they work with your skin.

  • CosRX is afforable and effective skincare. I love their Snail Mucin and Pimple Patches and I love that they are widely available to shop from their website to Amazon. Their packaging is simple and effective as well, no bells and whistles.
