  • How It Works

    A must-have in everyone’s skincare regime, this is our cult-favorite hydrating serum to visibly condition and nourish the skin.


    1. Hyaluronic acid is a large sugar molecule that occurs naturally in the skin. It is responsible for filling the gaps between skin cells, visibly plumping up the complexion while also keeping its structure in place. Incredibly, it also has capacity to hold 1,000x its own weight in water by drawing H2O molecules to itself like a magnet.

    2. Combined with Vitamin B5, Hydr8 B5 helps to boost the skin's ability to retain moisture. The result is visibly soft, supple and hydrated skin.

  • How To Use
    1. Massage 6 drops of Hydr8 B5 across the face, neck and décolletage

    2. Leave to absorb before applying moisturizer

    3. Repeat every morning and evening 

    4. Patch testing prior to use is advised. Refer to medik8.co/patch for an in-depth guide to patch testing.

  • The Science Behind

    “Hyaluronic acid works to attract moisture and retain it, and is able to hold up to 1,000x its own weight in water. It helps to boost hydration within the skin for a healthy-looking and visibly supple complexion. Hyaluronic acid also helps to support the skin’s natural barrier, so it doesn't lose water as quickly throughout the day. Skin is left with long-lasting moisture.”
