    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.
