Avène Hydrance Boost Concentrated Hydrating Serum

A water-light hydration boost for thirsty skin

Hydrance Boost Concentrated Hydrating Serum is the booster of Avène's Hydrance range, made for dehydrated, sensitive skin of every type. Enriched with hyaluronic acid and vitamin B3 (niacinamide), it hydrates for up to 48 hours, strengthens the skin's moisture barrier and restores the balance of dehydrated skin, leaving it comfortable, soft and supple. It also helps fight a dull look for smoother, healthy-looking skin. It comes in a 30ml pipette bottle and is made in France.

Formula and texture

Rich in Avène Thermal Spring Water, known for its soothing and softening properties, the formula contains 96% ingredients of natural origin and no ingredients of animal origin. The fresh, ultra-light water-gel texture is non-greasy and non-sticky, melts in at a touch of the fingertips and leaves a veil-of-water feel on the skin. Use it on its own or under your moisturiser; it also works as a make-up base. Gentle, light scent. The formula is cold-processed and biodegradable (OECD 301), in mostly recyclable packaging.
