Using the Matrixyl 3000 peptide, this smoothing and hydrating serum mimics the effect of what natural collagen would do to your skin, helping it appear plumper and firmer. Syn-Tacks Dual Peptide also gives an added boost and can help decrease appearance of fine lines and wrinkles. Review: Lightweight, Hydrating & Actually Noticeable Results - I’ve been using this collagen peptide serum for a few weeks now, and it’s quickly become part of my daily routine. The texture is very lightweight—almost watery—so it absorbs fast and doesn’t leave any sticky or greasy feeling. That’s a big plus, especially if you layer other skincare or wear makeup. What I noticed most is how hydrated and plump my skin feels after using it consistently. My skin looks smoother, and there’s a subtle glow that wasn’t there before. It hasn’t caused any irritation, which is important for me since I have combination skin. I also like that it works well with other products—I’ve paired it with moisturizers and sunscreen without any pilling. A couple things to keep in mind: results are not overnight, but with consistent use, you do start to see improvement. Also, if you’re expecting dramatic anti-aging effects immediately, this is more of a gradual, skin-supporting product. Overall, it’s a solid, affordable serum that delivers hydration and helps improve skin texture over time. I’d definitely repurchase. Review: A necessary step in skincare routine - I have very sensitive, dry, and oily skin. When I forgot to apply it after cleansing, I immediately noticed a difference in how my skin felt when I finished applying my moisturizer. My skin felt drier and the moisturizer didn't feel as effective. Water definitely does not act as a "base layer" of moisture the way a serum does, so no, the serum isn't pulling a placebo effect. I think this serum reinforces what the regular moisturizer does, so I am glad to have added this step with the right product. I have used so many other serums like Timeless's CoQ10 and Matrixyl, PC's Niacinamide, and other hyaluronic acid serums. Inkey List Collagen Serum works much better and is much less expensive. Although the others did give me the base layer of moisture, the level of moisture doesn't feel as strong and also didn't do anything better than the Inkey List serum. Even though Coq10, matrixyl and niacinamide are said to be huge promoters of cellular skin activity, my skin was no different when not using them. Not saying those things don't work but when compared to this very basic and cheaper IL peptide serum, the results aren't there. This has no scent, feels silky and clean, absorbs quickly, doesn't burn. My skin feels immediately soothed. I use slightly less than 1/8 tsp for my whole face and neck (sweeping outward) two times per day after cleansing. One bottle lasts me 1.5 months, so I stock up. This is a staple. Very grateful for this product. ## Features - COLLAGEN PEPTIDE SERUM - A serum that works to make the skin appear plumper and firmer, to help reduce the appearance of fine lines and wrinkles. - POWERFUL INGREDIENTS - Using the Matrxyl 3000 peptide, this smoothing and hydrating collagen serum mimics the effect of what natural collagen would do to your skin, helping it appear plumper and firmer.

Both times I ordered this it did not have a seal under the cap.** A: Mine didn't have a foil seal or that plastic seal usually around the outside of cosmetics. **Q: In what order is this serum applied if you use other things on your face like Vitamin C, moisturizer and sunscreen (which I use every morning)?** A: I only use it at night as an alternative to the nights I use Retinol. I use hyaluronic then the peptide then the night moisturizer. I was always told to use the thinner serum first. But I'm not a specialist. **Q: Whats the ingredients?** A: KEY INGREDIENTS; Matrixyl 3000™ helps to boost collagen production Syn®-tacks, a dual peptide, that helps provide collagen boosting benefits Water (Aqua / Eau), Glycerin, Butylene Glycol, Propanediol, Phenoxyethanol, Hydroxyethylcellulose, Sodium Phytate, Citric Acid, Leuconostoc/Radish Root Ferment Filtrate, Carbomer, Hyaluronic Acid, Sodium Lactate, Palmitoyl Dipeptide-5 Diaminobutyroyl Hydroxythreonine, Palmitoyl Dipeptide-5 Diaminohydroxybutyrate, Polysorbate 20, Polysorbate 60, Disodium Phosphate, Sodium Phosphate, Palmitoyl Tetrapeptide-7, Palmitoyl Tripeptide-1. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Lightweight, Hydrating & Actually Noticeable Results *by F***Y on April 23, 2026* I’ve been using this collagen peptide serum for a few weeks now, and it’s quickly become part of my daily routine.
