Scent: 6 Multi Peptide Complex (1 Pack)
I’ve been using this skin booster for a while, and I absolutely love it! It leaves my skin feeling hydrated, smooth, and refreshed, and I’ve noticed my complexion looks healthier and more even over time. The lightweight texture absorbs quickly and layers well with the rest of my skincare routine. The only downside is the bottle. It doesn’t look very nice and feels a bit cheap compared to how amazing the product inside is. I really hope the brand improves the packaging because the formula is truly excellent. Overall, I highly recommend it and will definitely purchase it again.

Scent: 6 Multi Peptide Complex (1 Pack)
Wow. Years ago (I'm 52), in the mid-aughts when I started realizing I needed to care for my skin, quality products (outside Cera Ve) either required a prescription or were awfully expensive. You really had to pick and choose what you purchased, and it always came at a cost. Fast forward to now, and the product lines like COSRX , The Ordinary, the Inkey and more really have brought incredible skin care to an affordable price point. I was looking for a copper peptide serum that was a little less expensive than the one I was using ($40 for a .5 oz bottle). I saw this on special and decided to try it out, as I have liked some of their other products. I'm quite impressed after using for a little less than a week. One thing I think this does is really help distribute my other serums more evenly; in addition to copper peptides and nianamiacde in my regular rotation I use a growth factors serum, azelaic acid, and vitamin C, but I always feel like I have issues getting coverage. By starting with this, then layering the others, I find I get much better coverage. In general, just a few days in my skin is looking much more hydrated and even my fine lines and wrinkles are less prominent. (Its almost winter in Maine right now and hydration is a serious challenge.). The woman who put this on her lips - thank you! Genius. It really makes a difference. In addition to this, I find this product alone leaves my skin really smooth and hydrated under makeup. Its super lightweight and really helps achieve a good finish, and really lasts all day to boot. While Im a little old to achieve a "glass" finish I imagine a younger person could really nail that look with this.

Scent: 6 Multi Peptide Complex (1 Pack)
Fairly inexpensive product to add to your a.m. and p.m. routine. I noticed that it has definitely softened my dry patches and calmed down the redness in my face. No greasy residue and works well with my makeup application The biggest difference for me has been in my PM routine. Although I keep it in my daily routine, adding it to my nighttime routine, I noticed a better poor tightening effect and firmness of my skin. Pair this with the the maelove peptide squad. The Cos RX is a penetration booster allowing the maelove skin serum to penetrate much deeper into your skin tissue. Noticed a difference since I added these two products together in my PM routine. Combining the two in just two weeks, I noticed my skin has a Dewey look, and my pores definitely look smaller around my nose and cheeks. I love how my skin feels incredibly soft to the touch. I think this combination is a marathon not a sprint for my overall results to just get better overtime.

It offers some hydration. I like how it enhances skin texture, and effectively diminishes the appearance of some dark spots and discoloration. It is gentle and has Helped and Improved My Skin and Face Very Much. I like how it improves the look of face skin for a fresher, more better good looking appearance. It helps to improve the appearance of skin. It does well with to visibly reduce the look of dark spots and post-acne marks. It is pleasant, decent, satisfying, nice and effective.

Scent: 6 Multi Peptide Complex (1 Pack)
My skin is VERY dry and, directly after washing, once I pat my skin dry it will tighten and dry out in seconds if I don't get something on it quickly to keep the moisture in. This product is what I usually apply first. And, if my skin did dry out before I could get it on, this rehydrates it. This product is aptly described as a toner-serum. It's lightweight and fluid and primes my skin with hydration as well as copper peptides, niacinamide, and hyaluronic acid for water retention (it's nice to have all three in the same product) before I add a cream or oil over the top to seal it in. I usually let it sit on my face, neck, and décolleté for a couple of minutes before adding a heavier product so that it has time for the ingredients to penetrate. If needed and it dried, I may mist my face lightly with something watery to wet it again before adding a cream or serum. But often I will just add the cream or serum while it's still wet and it helps those products glide more thinly and evenly. This product has several ingredients I look for all-in-one and the formula seems free of unnecessary chemicals. It definitely helps streamline my skincare routine.

I’ve been using this snail mucin for almost a year, and it has become the one product I never want to run out of. At 53 years old, my skin has never looked smoother or more even. My complexion has a healthy glow, feels incredibly hydrated, and I really don’t have many deep fine lines. What I love most is how soft and plump my skin feels, especially when I wake up in the morning. It absorbs beautifully, isn’t sticky, and layers perfectly with the rest of my skincare routine. Over time, I’ve noticed brighter, calmer, healthier looking skin with a texture that’s noticeably smoother. I’ve actually received compliments on my skin, and I truly believe this product has played a big part in that. If you’re looking for something that delivers real results with hydration, texture, and radiance, I can’t recommend this enough. It’s earned a permanent place in my routine, and I’ll definitely keep repurchasing! 💕

The COSRX 6X Peptide Collagen Skin Booster Toner Serum is one of those rare “first step” products that actually makes a visible difference. The texture is ultra‑light — almost watery — but it absorbs immediately and leaves the skin feeling smoother and more refreshed. It’s packed with six peptides and collagen, so it gives the skin a subtle plumping effect right after application. After using it consistently, I noticed my complexion looking more even and less dull. It layers beautifully under serums and moisturizers, and it really does help the rest of your routine absorb better. This booster adds that healthy, hydrated glow without any heaviness or stickiness. It’s gentle, fast‑absorbing, and perfect for prepping the skin for the rest of your routine. A great choice for anyone dealing with dullness, uneven tone, or loss of firmness.
