A hydration booster that keeps sensitive skin comfortable for 72 hours
Bioderma Hydrabio Serum is a hydrating booster serum for dehydrated, sensitive skin. Its patented Aquagenium+ technology helps skin reactivate its own hydration mechanisms and replenish its natural moisturising factors, while high-molecular-weight hyaluronic acid and glycerin hold water in the skin. Niacinamide helps skin make its own lipids, and a prebiotic sugar supports a healthy microbiome. Bioderma reports +176% immediate hydration, with results that last up to 72 hours.
The texture
A light gel-serum that absorbs within seconds and leaves skin soft and plump, never sticky. It layers easily under cream or makeup.
Who it suits
- Dehydrated skin that feels tight during the day
- Sensitive skin that needs a gentle serum
- Normal to dry skin in heated or air-conditioned rooms
- Anyone who wants a hydration boost before moisturiser
Worth knowing before you buy: it contains fragrance. Very dry skin will still need a nourishing cream on top, such as Bioderma Hydrabio Crème Rich.
How long one bottle lasts
Used morning and evening, the 40ml bottle lasts about two months.
