Review: Powerhouse product for the cost - 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.
Review: Excellent Product For Sensitive Skin - Excellent product! This is a great product to use after cleansing your skin. My skin type is combination and very sensitive. I often breakout or get a rash from trying new products, but I did not with this. It is very gentle and works great for sensitive skin. My skin tends to get very dry during winter as I live in the north. This helped to keep my face more balanced and not as dry without it feeling sticky as some products feel. I use 1-2 pumps onto my fingertips and spread it evenly all over my face. I do another 1-2 pumps for my neck as well. This leaves my skin with a natural glow (not greasy looking). Make sure it fullly dries before applying your next step in your skin routine or applying makeup.

### ⭐⭐⭐⭐⭐ Bery good product for antiaging and brighter skin.
*by I***A on January 23, 2026*

It's the 3d week of using this fot me. I noticed that my skin became calmer, nicer, glowing and more hydrated after 2 weeks. Now I have added the ordinary niacinamide & retinol to my routine. Using this peptide serum before niacinamide day and night, worked super for me. Will buy more.
