Medik8's Hydr8 B5 Serum is a lightweight, oil-free hydrating treatment formulated to flood skin with a wave of lasting hydration. This concentrated 30ml serum combines multiple molecular weights of hyaluronic acid with the power of Vitamin B5 for immediate and long-lasting hydrating results.

Why You'll Love It

Medik8 believes in simplicity — skincare without the fuss. This serum embodies that philosophy with a streamlined, effective formula that does exactly what it promises: deeply hydrate without complication.

Its secret: hyaluronic acids at multiple molecular weights (small, medium, and large). This strategic combination attracts and retains up to 1000 times its weight in water, flooding skin with hydration at every layer. Lightweight and transparent, this serum penetrates without any greasy or sticky residue.

The infusion of Vitamin B5 (panthenol) strengthens the hydrating action while visibly smoothing the appearance of fine lines and wrinkles. Calcium pantothenate (a Vitamin B5 derivative) completes this soothing and regenerating action. Result: skin plump with hydration, supple, and visibly smoother.

Thanks to its concentrated, minimal formula, this single serum can replace several traditional hydrating products — maximum efficacy, minimum fuss.
