I started with the cleanser and was so impressed that I ended up buying almost the entire COSRX line. The Advanced Snail Mucin Gel Cleanser leaves my skin feeling super clean without drying it out or making it feel tight. After seeing how well my skin reacted, I added the toner, snail cream, vitamin C serum, retinol, eye cream, and sunscreen to my routine — and every single product has been amazing.

My skin feels smoother, more hydrated, brighter, and healthier overall. The snail mucin products especially give my skin such a soft glow, and the retinol/vitamin C combo has really helped improve texture and dark spots. The sunscreen is lightweight and doesn’t leave a white cast, which I love.

Honestly, COSRX completely upgraded my skincare routine. My skin has never looked this good, and now I understand why so many people rave about this brand. Definitely worth every penny!

I started using this serum almost three years ago, and at this point, it has become one of those products that stays in my routine without much thought because I know it works for me. I’ve tried plenty of skincare products over the years that were popular for a while, only to be forgotten. This one stuck.

The first thing I noticed was how hydrated my skin felt after using it. Even now, after years of use, I still like how soft and smooth my skin feels afterwards. It gives my skin a healthy, moisturized look without feeling heavy.

The texture can seem unusual at first because of the snail mucin, but it absorbs better than people might expect. I use it consistently, and my skin feels more comfortable and less dry when it’s part of my routine.

I’m 52, so I care less about miracle claims and more about whether a product actually keeps my skin feeling good over time. For me, this has been one of those products. The fact that I’ve continued using it for nearly three years says more than a first-week impression ever could.

A little goes a long way, and one bottle lasts longer than expected.

I know skincare is personal, and what works for one person may not work for another, but this has earned a permanent place in my routine.

Easy 5 stars from me.

I’m really happy with this Korex face serum. It feels lightweight on the skin, absorbs quickly, and doesn’t feel sticky at all. After using it regularly, my skin feels smoother, softer, and more hydrated. It also gives a fresh and healthy glow.

The packaging was good, and the product arrived in perfect condition. A little goes a long way, so the bottle should last nicely.

Overall, a great serum for daily skincare. I’m satisfied with my purchase and would definitely recommend it!

As someone with sensitive skin, I really appreciate products that are both effective and gentle—and this one delivers. The COSRX Snail Mucin Repairing Serum absolutely lives up to the hype. It’s simple, straightforward, and consistently effective.

I use it after cleansing and applying a hydrating toner. In the morning, I layer my daily SPF on top, and it noticeably boosts hydration throughout the day. In the evening, I apply it before tretinoin, followed by moisturizer, and it helps buffer potential irritation while keeping my skin comfortable.

It’s lightweight, deeply hydrating, and non-irritating—this has easily become a staple in both my morning and evening routines. For the price, it’s an incredible value.

I have repurchased many times and will continue to do so.

The only thing to note is the texture—it has that signature slightly sticky, “snail mucin” feel. Personally, I find it comforting and protective, but I can see how it might not be for everyone.

But here i am today! No regrets!

I saw this item all over social media and finally decided to try it. It’s not terribly expensive, so if it didn’t work out, i really wouldn’t be out that much.

I had zero expectations for this. I was just curious about it. Would it be really sticky? Would it smell like a snail?

This feels pretty much exactly as you’d expect for something derived from snail mucin. It’s definitely what i would call sticky and a bit runny when you put some on your finger. A little bit goes a long way with this! I rub it into my skin after astringent, and it has a wonderful cooling feeling if i apply astringent too soon after a hot shower.

It takes just a moment to be absorbed into your skin. I do follow this up with an SPF moisturizer.

As far as its ability to correct skin issues, i can’t really comment on that. I don’t suffer from uneven, dry, blotchy, red skin. As with most women my age, i like to use a basic hyaluronic acid or retinol most days. I did stop using those for a few days when i first added the snail mucin to my routine, but then i noticed this annoying fine line by my mouth coming back, so i went back to using my regular products after astringent, before snail mucin. It’s worked out well!

The snail mucin doesn’t feel sticky or greasy after it dries, and it adds fantastic moisture to your skin. Again, i can’t speak to the product addressing skin issues that i don’t have, but i can say that it didn’t do anything for me in terms of making fine lines lessen.

I recommend this if you want a little extra moisture. And I’d still recommend a lightweight SPF moisturizer on top of this since it doesn’t have one. Just don’t expect it to work miracles in terms of anti aging.

This is still a very good serum for me. Every time I start my skin feeling a little stressed out I make sure to use my Cosrx Snail Mucin. It is a repairing serum that helps calm my skin. It truly hydrates and makes my skin super soft. Key ingredients like the snail secretion are still great for my skin.

I’ve been using this COSRX Snail Mucin serum for a little while now and honestly I can see why so many people love it. My skin feels more hydrated, smoother, and looks healthier overall. I especially noticed a nice glow after applying it, and it doesn’t feel heavy or greasy on my face.

A little product goes a long way, and it absorbs really well into the skin. I also love that it works great under makeup and doesn’t irritate my sensitive skin. Definitely became part of my daily skincare routine. Highly recommend if you want soft, glowing skin! ✨

I've been using this serum since it was introduced (and sold for under $10). It is healthy gorgeousness in a bottle. I have multiple skin conditions (rosacea, dermatitis, uneven tone and texture, etc.) and it has improved my skin overall. No irritation (I'm super sensitive), no breakouts, not greasy. Just luscious, snail slime goodness! It is calming, soothing, hydrating, and has resulted in better texture and slightly more even tone (rosacea is challenging).

~ I love it on top of licorice serum, azalea acid and niacinamide. It does create glass skin; try the version that includes niacinimide for a slightly lesser sheen. I use plain rice paper to absorb excess oil during the day. This is a holy grail product along with Dermalogica PreCleanse, Cerave or Cetaphil cleansers, Meebak Cica toner and LaRoche Posay Cicaplast.

Best product ever. I am waiting for it to be available for my second order.

Has great absorption, leaves skin hydrated feeling a difference after 1st week

Great value for money

haven't tried it yet but it seems cool

This leaves a nice glow
