Wow! Really LOVE!
Okay, my skin barrier is horrid after having children and years of essentially stripping all of the oil off my face as a teen. I’m very dry and almost get a gritty feeling at times. This has pretty much cleared that up after just a few days of consistent use. I use these after my daily shower and cleanser. I’ve seen others raving about the snail mucin in the past and thought I’d try it. I’m glad I did. The only thing I regret is not trying this sooner. Seriously. The truly clean and glowy look you get after you’ve applied your peptides and snail mucin is worth this price all day. Great job on this bundle Amazon!

Transform Your Skin Naturally with COSRX Snail Mucin 96% Peptide Booster Set
I’ve been using the COSRX Snail Mucin 96% Peptide Booster Set daily since the beginning of 2023, and honestly, it’s been a game-changer for my skin. This set is now my only skincare routine, and I haven’t felt the need for anything else. Before I started using it, my skin struggled with acne and visible pores. After consistent use, I’ve noticed a dramatic improvement, my skin feels smoother, looks brighter, and has achieved that coveted “glass skin” glow. My acne is completely gone, except for occasional hormonal breakouts around my chin, which is very normal. The overall texture of my face has improved so much that pores are barely visible, leaving my skin soft, shiny, and healthy. What I love about this set is not just its effectiveness, but also its gentle, nourishing formula. The snail mucin works wonders for hydration and healing, making it suitable for sensitive or acne-prone skin. The peptides help restore elasticity and firmness over time. Alternative uses: I’ve even started using a few drops of the serum on dry areas like elbows and cuticles, and it keeps them moisturized and smooth. It’s truly versatile and feels like a small self-care ritual every day. If you’re looking for a natural, reliable, and results-driven Korean skincare set, this COSRX Snail Mucin Booster is worth trying. It’s perfect as a gift for women or anyone who wants healthy, radiant skin. Pros: • Daily hydration and nourishment • Improves skin texture and elasticity • Reduces acne and minimizes pores • Leaves a smooth, glassy glow • Gentle on sensitive skin Cons: • Might take a few weeks for visible results, so patience is key • Occasional hormonal acne may still appear I highly recommend this set for anyone seeking real, long-term skincare results without harsh chemicals. It’s more than just a serum, it’s a daily investment in healthy, happy skin.

Love this Bundle!
First of all, I absolutely Love Cosrx! It is one of my top favorite Korean skincare brands! I will never be without the 6 peptide Skin booster! It feels so good on the skin and soaks in really quick! the skin booster doesn't have a smell at all. Now I really like the vitamin C serum I'm actually on my second bottle that I have bought from Cosrx! It does have a weird smell, and you have to keep it refrigerated so that it doesn't lose all its goodness. It works really well too I've notices some softening of my dark spots but its not drastic, but I don't use it every night either. I am acne prone, so I like to rotate my skincare especially with that much vitamin c. If you do not refrigerate it, it will start becoming a darker color and the smell gets a little stronger. I read that's because it is losing its potency. The price to get both these products in this bundle together is so much better than buying them separately. Using these products together make my skin so pretty! I only use the Vitamin c at night, but I use the peptide booster every single day, day and night. I had a bad bout of acne a year or so ago and cosrx and Korean skincare literally saved my skin! both are very effective and not too harsh on my skin. I am defiantly buying more soon!

Dynamite duo for skin
I’ve been using the snail mucin serum for about 3/4 years when I heard about it from TikTok and it’s become my staple product that I use everyday. I’ve never used or heard about the benefits to peptides for skin until I seen some YT shorts of multiple dermatologists raving about them. I seen this duo on Amazon and since I already liked a the snail serum, maybe the peptides serum is just as fab. It absolutely is. Even better because it comes as a set. I cannot be without this. I’ve noticed a huge HUGE difference in the quality of my skin. I look more hydrated and brighter. The texture has evened out. This product is amazing. Don’t expect drastic results overnight. While it does improve right away after first use, skincare is about consistency and time and knowing miracles don’t happen overnight. It takes time to work to its fullest use and patience. But it does work wonders when you do. I highly recommend this for all ages and skin types.

Very effective Skincare for plump glass skin
I have been using this every day for over a year now. Its my holy grail. If im being super lazy and only do 1 step its this. I really love Cosrx, their products are very quality and have enough of the active ingredients to really see a difference in your skin. If you're on the fence, give it a try. I was so impressed when I discovered their products.

Ok product but smell is weird
Peptide serum was thinner than expected. Don’t think it will be like the snail mucin. It is light but soothing. The vitamin C serum is a little crazy, out of the bottle it smells like cat food/tuna tbh but when it rubs in it doesn’t smell like anything. It’s moisturizing & made my skin feel nice. Still not sure if I’ll repurchase.

Ho iniziato a usare i prodotti di COSRX (Snail 96 Mucin Essence + Peptide Booster) da qualche settimana e devo dire che sono rimasta davvero sorpresa. La texture della snail essence è particolare all’inizio (un po’ “gelosa”), ma si assorbe bene e non lascia la pelle unta. Anzi, dopo pochi minuti la pelle risulta molto più morbida e luminosa. Ho notato già dopo pochi giorni: • pelle più idratata • meno zone secche • effetto “glow” naturale Il peptide booster invece aiuta tantissimo a far assorbire meglio tutto il resto della skincare. Da quando lo uso sento che i prodotti funzionano di più.
