From the age of 20, hyaluronic acid synthesis decreases and is of poorer quality: water reserves decrease, and the skin becomes dehydrated, sagging, and wrinkles and fine lines appear.

BIODERMA Hydrabio Hyalu+ Serum intensively restores skin hydration with long-lasting results, limiting the first signs of aging. HYALU+ technology, which contains high molecular weight hyaluronic acid and self-hydrating sugar, teaches the skin to reactivate its natural moisturizing mechanisms and retain the water it needs to maintain its balance. It helps to strengthen and protect the skin's internal reserves of hyaluronic acid.

In turn, low molecular weight hyaluronic acid helps the skin regain firmness and tone.

Niacinamide strengthens the protective function of the skin barrier.

Carnosine protects against oxidative stress.

The serum is very well tolerated; its texture is light and refreshing. BIODERMA Hydrabio Hyalu+ serum is quickly absorbed into the skin and forms a non-sticky coating.
