1 / 7The 6 Peptide Skin Booster Serum
A thin, water-like serum that packs six different peptides into a texture closer to a toner than a traditional serum. It sinks in fast and feels like almost nothing, which makes it easy to slot in as a first hydrating, firming step. Aimed at people starting out with peptides or wanting early support for fine lines and dullness without a heavy formula.
More detail
The name refers to six peptides, including acetyl hexapeptide-8, copper tripeptide-1, and palmitoyl tripeptide-8, that act as signal ingredients for firmness and elasticity, rounded out with niacinamide for tone and glow plus panthenol, hyaluronic acid, adenosine, and allantoin for hydration and calm. The texture is lightweight and non-sticky, absorbing almost instantly with no residue. Apply a few drops to clean skin and pat in as your first serum step, before any heavier serums and moisturizer, morning and night. Because it is fragrance-free and gentle, it layers well and suits most skin types, including those newer to active ingredients. Peptides work gradually, so treat it as a steady-use product rather than a quick fix.
