COSRX 6 Peptide Skin Booster Serum 150ml | K-Beauty Anti-Aging Firming Serum

The COSRX 6X Peptide Collagen Booster Toner Serum is one of the best peptide products I’ve ever used! I already finished my first bottle and am now on my second. I noticed a big improvement in my sagging skin (caused by retinol use) — my skin feels firmer, smoother, and back to normal again.I highly recommend this serum to anyone who wants to bring back elasticity and a rejuvenated glow to their skin.

Love Cosrx - it's one of my go-to skincare brands and I am rarely disappointed.This 6x Peptide Collagen Booster Toner is one of my favorites and I have repeat ordered. But it does last a long time as a little goes a long way so I don't have to order it that often.It glides on beautifully and gives my skin such a nice glow.It's not greasy at all. It absorbs quickly.I like to order it on sale or on Prime day as I did this time but all of Cosrx's prices are reasonable, which makes this brand even better as the value is so great.This toner/serum is very hydrating. My skin loves it. I can get Rosacea redness and this doesn't irritate my skin at all--no redness, no itchy feeling, no irritated skin.Fragrance free.Just love it!

This confuses me but it’s nice. I thought it was a facial Mist but it’s not. It has a squirt top which I love but it’s thicker like a like a phyto-mucin so it fits into the serum part of your routine. I like that it’s scent free for the most part and love how it helps my skin. I give it a 4 and not a 5 mostly bc I didn’t and still don’t entirely understand the product.

Sensitive skin friendly, lightweight, hydrate your skin, fragrance free, good absorption,makes skin softer. Its non comedogenic. But Does give you glass skin but good for skin.

Words cannot express how impressed I am with this serum! I noticed an immediate difference in my skin's appearance. It makes my dry, diabetic skin look smooth, balanced, toned and reduces redness. It has even softened and reduced redness around an old neck scar I have from surgery.Since I have problem rough/bumpy skin, I have actually used this serum on my entire body with amazing results. Unfortunately its a bit too pricey to continue all over application. I do wish they made a body serum!

Glowy, Firm, and Hydrated Skin – A New Staple!I’ve been using the COSRX peptide serum for several months now, and I’m honestly loving the results. My skin feels noticeably firmer, smoother, and more hydrated, especially in the mornings. It has a lightweight, watery texture that absorbs super fast and layers perfectly under my moisturizer.What I really appreciate is how gentle it is — no irritation or breakouts, even on my sensitive skin. My complexion looks brighter and more refreshed, and I’ve even seen a softening in some fine lines around my eyes and forehead.The bottle may look small, but a little goes a long way. If you’re looking for a boosting serum that actually does something, this is a great addition to your routine, especially if you’re focused on anti-aging or skin resilience.

Hello to all skincare lovers! I just started using COSRX 6X peptide collagen tonic serum and I'm impressed! My skin feels much more hydrated from day one, something that doesn't always happen with tonics. Niacinamide is a star ingredient for spots and pores, and it seems to be working wonders. In addition, hyaluronic acid gives a juicy and healthy glow to the skin. The texture is light and absorbs very quickly, perfect for use before moisturizer. Honestly, I highly recommend it! If you are looking for a product that gives you hydration, brightness and helps you with the appearance of pores, this is the right one.

The COSRX 6X Peptide Collagen Booster Toner Serum has become another standout addition to my daily skincare routine, proving once again why COSRX consistently delivers quality products. I use this as part of a complete COSRX regimen alongside their Advanced Snail Mucin Gel Cleanser and Snail Mucin 96% Power Repairing Essence, and the synergy between these products has resulted in marked improvements in both skin smoothness and hydration levels. What I particularly appreciate about this toner serum is its lightweight, non-sticky formula that absorbs quickly without leaving any greasy residue, making it perfect for layering with other products. The concentrated formula means you only need a small amount per application, which makes this product exceptionally economical and provides excellent value for money. It's become an indispensable part of my skincare routine that seamlessly integrates with other COSRX products for comprehensive skin improvement.Pros:Excellent addition to a complete COSRX skincare routine with proven synergyDelivers noticeable improvements in skin smoothness and hydrationLightweight, non-sticky formula that layers well with other productsQuick-drying without greasy or heavy residueConcentrated formula - a little goes a long way for exceptional valueSeamlessly integrates into daily skincare regimenCost-effective due to small amount needed per applicationConsistent quality from trusted COSRX brandCons:Haven't found any significant drawbacks
