  • Key Benefits
    • Targets Signs of Skin Ageing
      As Liquid Peptides is massaged into the skin, the 30% peptide complex starts its multi-faceted approach to rejuvenating the skin. Fine lines and wrinkles are visibly smoothed as the lightweight serum provides you with the very best in anti-ageing technology.
    • Deeply Hydrating

      The ultra-hydrating, crystal-clear serum that sinks effortlessly and rapidly into the complexion, helping to boost hyaluronic acid levels in the skin.

    • CSA Complement

      Liquid Peptides perfectly complements vitamin C application in the morning, and vitamin A application at night - enhancing the results of the Medik8 CSA skincare strategy.

  • How It Works

    Peptides often find it difficult to get to where they need to be; they are large and dislike being around oil so they struggle to fit through the small, oil-based gaps between skin cells. Our 30% peptide blend contains an innovative delivery system which ensures that all our peptides can dive deep into the lower layers of the skin for optimal effect.

    1. Drone-targeted copper peptide specifically targets fibroblast cells; skin cells responsible for making collagen and elastin. As the copper peptide is released into the fibroblast, collagen synthesis is stimulated and fine lines and wrinkles are smoothed in appearance.

    2. MATRIXYL™ 3000 tricks skin cells into producing more collagen, while Expression Line Peptide blocks signals for muscle contraction to minimise the appearance of expression wrinkles.

    3. Carnosine protects from glycation-based skin ageing while hyaluronic deeply hydrates, as prebiotics rebalance the skin’s natural microbiome.

    Drone-Targeted Copper Peptide

    A collagen-supporting copper peptide encapsulated in a polymer system which dives through the layers of the skin to specifically target collagen-producing cells.

    ​MATRIXYL™ 3000*


    ​Expression Line Peptide

    An innovative peptide which works to fight expression wrinkles by minimising muscle contraction. Expression Line Peptide can block nerves from sending signals for the muscles to contract, visibly minimising the appearance of expression lines.

  • The Science Behind

    "Liquid Peptides is a jam packed peptide formula. Its true innovation is a drone-targeted copper peptide which swoops deep into the layers of the skin to deliver peptides where they really need to go. A copper peptide is encapsulated in a polymer shell, with external peptides which fit into receptors ('ligands') on the outside of collagen-making fibroblast cells. This means that the capsule is directed, like a drone, specifically to fibroblasts. When inside, the polymer encapsulation is naturally broken down and the peptide inside can diffuse out of the encapsulation, stimulating collagen and elastin production for plumper, more youthful-looking skin."
