Loss of firmness and skin dehydration are the first symptoms your skin manifests when aging. The skin looses its elasticity and fine lines start to appear. To fight the first signs of aging, it is essential to hydrate the skin with skin care products featuring active ingredients recommended by dermatologists.

The Hyalu B5 serum has been specially formulated to help fight loss of firmness by replumping the appearance of the skin, repairing the skin's barrier and activating skin renewal. La Roche Posay's Hyalu B5 skin care products, including a highly concentrated serum, combine 3 active ingredients: hyaluronic acid, vitamin B5 and madecassoside.

Hyaluronic Acid is the reference molecule in anti-aging skin care lines. It naturally occurs within the skin however, as we age levels of hyaluronic acid start to decline. Treating your skin with hyaluronic acid skin care products becomes a necessity if you want your skin to look younger and brighter.

The ingredient serves two purposes:

1. It provides your skin with an in-depth hydration.
2. It plumps, firms and tightens the skin, instantly reducing the appearance of fine lines.

The Hyalu B5 products contain two types of pure hyaluronic acid molecules working together to reduce the appearance of wrinkles and to increase skin volume.

Vitamin B5's two main benefits are soothing and repairing the skin. It stimulates the skin's regeneration and resistance by improving its natural repairing process.

Madecassoside acts as a booster: it amplifies the effects of hyaluronic acid and vitamin b5.
