Medik8 Liquid Peptides
An award-winning, ultra-hydrating serum powered by a 30% multi-peptide complex. 13 age-defying peptides — including copper peptides and Matrixyl® 3000 — work in synergy to visibly smooth fine lines, boost firmness, and restore youthful plumpness.
Copper Peptides
Fragrance-Free
All Skin Types
This crystal-clear, lightweight serum sinks effortlessly into skin to deliver next-generation anti-ageing technology. The 30% peptide complex boosts collagen and elastin production, smooths the appearance of fine lines and wrinkles, and elevates the skin’s natural stores of hyaluronic acid.
Enhanced with drone-targeted copper peptide technology for precision delivery, expression line peptides to target dynamic wrinkles, and nourishing prebiotics to support a balanced skin microbiome. The result is skin that feels soft-to-touch, deeply hydrated, and visibly more youthful.
