Known for holding up to 1,000x its own weight in water, multi-weight hyaluronic acid draws and binds water from the atmosphere into the skin. Using an optimum blend of hyaluronic acid weights ensures skin is seriously moisturised from the deepest layers right up to the surface.

This powerful serum is also enriched with vitamin B5, which enhances water retention and skin regeneration, leaving your skin plump, hydrated, and revitalised.

Hyaluronic acid is a natural, sugar-based molecule found in the skin. It effectively fills in the spaces between skin cells, giving the complexion a plump appearance while maintaining its structure. This powerful ingredient can hold up to 1,000 times its weight in water, drawing in moisture like a magnet. Medik8 Hydr8 B5 utilises a variety of hyaluronic acid sizes to deeply penetrate the skin, drawing hydration up from the layers below. Larger sizes sit on the surface, acting as a hydration reservoir to continuously nourish the top layers of the skin. In addition, Vitamin B5 enhances the serum's moisture retention and supports the skin's cell regeneration process, resulting in soft, supple, and well-hydrated skin.

Great product

Have purchased many times because it is so beautiful on my skin.

Good quality

Fast delivery and good price. I like this serum but it feels like it evaporates rates than soaks in, like others do. I love the Medik8 range for quality but will try a different brand for this product next time, to compare.
