Medik8 Hydr8 B5™

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



Hyaluronic acid is a large sugar molecule that occurs naturally in the skin. It is responsible for filling the gaps between skin cells, 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. Hydr8 B5 contains multiple sizes of hyaluronic acid. The smaller sizes are able to penetrate deep into the skin and draw hydration up from the lower layers. Larger sizes are too big to get into the skin’s network, but sit on top of the complexion acting as a hydration reservoir to continuously feed the upper layers of the skin with water.

Vitamin B5 boosts the moisture-retention of the serum and also supports the regenerative cycle of skin cells. The result is soft, supple and hydrated skin.

After cleansing in the morning and evening, massage 6 drops of Hydr8 B5 across the face, neck and décolletage.

Leave to absorb before applying moisturiser.

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