## Description

desertcart.com: COSRX 6X Peptide Collagen Booster Toner Serum with Copper Peptides, Niacinamide & Hyaluronic Acid Skin Renewal Boosting Facial Essence for All Skin Types, Korean Skin Care, 5.07 Fl.Oz : Beauty & Personal Care

Review: A must have - This booster serum is a powerhouse. It feels like a professional skincare treatment in a bottle. The formula is incredibly lightweight, almost watery, but it delivers intense hydration and firmness. My skin feels bouncy, smooth, and refreshed immediately after application. After consistent use, I noticed improved texture and a subtle tightening effect — especially around my cheeks and jawline. It layers perfectly with other products and never pills. The combination of peptides and niacinamide makes my skin look brighter and more even. This is one of those products that quietly upgrades your entire routine. It’s gentle, effective, and suitable for daily use. If you want that glass-skin glow, this is a must-have.
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.

### ⭐⭐⭐⭐⭐ Well-Designed “Toner Serum” That Improves Absorption & Overall Results
*by K***. on January 30, 2026*

This product is accurately described as a toner serum. It has the lightweight, fast-absorbing texture of a toner, but functions more like a treatment serum. Rather than focusing only on hydration, its real strength is how well it prepares the skin and enhances the performance of products applied afterward. With consistent use, I’ve noticed clearer skin, a brighter and more even tone, and gradual improvement in dark spots. The effect is especially noticeable when pairing it with active treatments such as vitamin C serums. How I use it (evening routine): In the evening, I apply a thin layer and gently pat until fully absorbed, then repeat this step 2–4 times, depending on how dry my skin feels that day. Building hydration gradually this way allows the skin to absorb moisture without heaviness and noticeably improves plumpness and overall moisture retention. Once the toner serum is fully absorbed, I apply my treatment serums (such as vitamin C), followed by a moisturizer with enough oil and hydration to seal everything in. Used this way, it clearly improves how well active serums absorb and perform, leaving the skin looking fuller, healthier, and well-hydrated. Morning use: I also use this in the morning, but usually apply just one light layer. It noticeably improves makeup application—foundation goes on more evenly, adheres better, and stays comfortable throughout the day without emphasizing dryness. I hope this review is helpful for anyone deciding whether this fits into their routine.
