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.

  • I love COSRX products for my sensitive skin, and I keep going back to this toner. It helps my almost breakouts disappear by the morning, and it’s a constant in my nightly routine. I take it with me when I’m traveling, too. I like to pair it with the 6 Peptide serum.

  • Really enjoy this cleanser! I typically use it when I’m in the shower in the morning. It smells nice and feels nice on the skin. It’s never drying, even in the winter. It does the job and I would repurchase in the future

  • These hydrogel eye patches are really good for reducing undereye puffiness and dark circles but you have to be patient and consistent with them. The texture can feel a bit off putting at first since they are more moist than usual under eye patches. I think they are a nice selfcare product but since they have snail mucin just be aware that they can feel slimy.

  • I mean she’s an OG. She’s been in the game for a while now she is hydrating. She’s smooth. She doesn’t leave a sticky residue. She doesn’t peel. I’ve loved this mucin essence for a long time but as I’ve grown up, I’ve realize there’s a lot better ones still almost done with this bottle and if I can’t find anything of comparison I still might come back to her

  • Cosrx pimple patches are the OG product even though soo many brands have come out with their own versions. I think these stick really well and are thick so they definitely cover any pimple or blemish. I like to leave them on overnight and normally dont wear them out/with any makeup.

  • I decided to try this toner after reading tons of reviews on it. Also I have tried a bunch of products from Corsx and they are great. But I have mixed feelings about this toner. I would prefer more other toners than this one. I have dry skin, so for me it made it dryer even more and it was uncomfortable to have that on my face. I felt it was removing all the hydration I was trying to acquire. Around my eyes were so dry that they felt like burning. Maybe this toner is not for me or dry skin. It does smell nice, I actually liked the scent. I didn’t noticed any difference with this product, maybe because I mainly felt the dryness on my skin than any worries with helping with acne or brightness. I agree that this toner is for acne prone skin, and maybe it was not suitable to me. I don’t recommend this product for dry skin and I will not purchase it again.

  • I cannot speak more highly of the snail mucin serum. When I got microneedling done for the first time, I upload ingredients photos of 15 different moisturizers I found online into ChatGPT and asked which formula would be the most soothing after the procedure. Cosrx won by a mile and I have been using it nightly long past the healing process from microneedling.

  • Loving this skin booster! It does exactly that…boosts your skin hydration and the effectiveness of your other skincare products. Though I wouldn’t really call it a serum; it’s more like a toner or lotion. It pats into your skin really well, and allows your heavier serums to sink in deeper. My skin is softer, smoother, and more hydrated. I’ve been using this morning and night and it has been working really well alongside my other skincare products. Would definitely recommend.

  • Was super impressed with these products, especially the Advanced Snail 96 Mucin Power Essence! It glides on the skin and makes me look like a jelly donut in the morning, amazing glow like none other product! I have super sensitive skin and I have never had any issues, very happy with it

  • Love the aloe sunscreen - light scent, moisturizing, fine for sensitive skin. Calming for redness prone skin. Simple packaging, although I've cut one open to get the last bit out. No white cast. Wish it came in a larger size.

  • These COSRX products have seriously become staples in my routine. I’ve been using the Niacinamide 15 Serum, Cleansing set and the Invisible Sunscreen for a while now, and they all just work so well together. The Invisible Sunscreen is probably my favorite out of the three. It’s lightweight, no white cast, and it doesn’t pill. If you’re building a basic routine that delivers results, these are 100% worth trying.

  • The master patch works great for the occasional skin blemish. Seems to clear them up in a timely fashion and is easy to use. I haven't tried other brand, so I don't have much to compare to. That said, it works and is a good price.

  • I like the lightness of this moisturizer. I'd say it's more like a sort of runny gel than a cream, which is perfect for summer and other times when I don't want something heavy. A little goes a long way, too!

  • 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.

  • If you’re looking for more hydrated, smooth skin with a healthy appearance, this product is perfect. I use it three times a week and apply it on slightly damp skin. My skin feels extremely hydrated, soft, and the texture has improved a lot.

  • Cosrx is one of my absolute favorite skincare brands! I have been using their whole bundle and it makes my skin feel amazing. It is great for sensitive skin. It makes my skin feel soft, healthy, and moisturized!

  • I am very impressed with The Alpha-Arbutin 2 Discoloration Care Serum. I have tried many OTC and prescription skincare products to try to fade my hormonal hyperpigmentation and post-acne scarring. Some of those products were very expensive and didn’t help me achieve the fading level I was anticipating. I have very fair skin and any type of dark spot is a big contrast between my skin tone. Dark spots take an extremely long time to fade so finding a product that will help speed that process up is important to me. I am shocked at how affordable Cosrx has made this serum. The ingredients are extremely high quality and potent. I like that the bottle is not clear so that it helps extend the potency of the serum. I like how the ingredients help support my already reactive and irritated skin, helps retain moisture in my skin and helps brighten my skin tone. It’s a very lightweight and thin consistency. It’s easily absorbed into the skin and it doesn’t leave any lingering residue on the skin

  • I like the snail essence from the this brand therefore have high hope on this dual essence. Would think is 2 times better but I am not too sure.
