Why it works
Power Peptides is a milky leave-on peptide serum designed to support firmness, elasticity, hydration and smoother-looking skin without adding exfoliation or retinoid activity.
Peptide support
Peptides are small amino acid chains that help support the skin’s structure. This formula uses multiple peptide technologies to support collagen and extracellular matrix activity, helping skin look firmer, smoother and more elastic over time.
Hydration support
Glycerin, butylene glycol, pentylene glycol, panthenol and saccharide isomerate help bind moisture. This supports a hydrated, more comfortable skin feel.
Routine compatibility
Power Peptides can be layered with other actives, including acids and retinoids. It adds peptide, hydration and comfort support, helping balance routines that may otherwise feel drying or active-heavy.
Key Ingredients
Matrixyl 3000 (Peptide Complex)
A peptide complex made with Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7. It supports smoother, firmer-looking skin and helps reduce the appearance of wrinkles.
Matrixyl synthe’6
A peptide technology based on Palmitoyl Tripeptide-38. It supports key skin matrix components for improved-looking firmness, smoothness and elasticity.
Tetrapeptide-21
