Information
The exceptional hydrating power of this serum is rooted in its thoughtfully curated blend of scientifically-proven active ingredients. At its heart lies high-weight Hyaluronic Acid, a molecule renowned for its remarkable ability to retain up to one thousand times its weight in water, drawing intense moisture into the skin's upper layers for immediate and lasting plumping effects. This is skilfully combined with Niacinamide, also known as Vitamin B3, which works to strengthen the skin's natural moisture barrier, enhancing its ability to retain hydration and defend against external aggressors. Together, these powerful ingredients deliver clinically proven 48-hour hydration, ensuring that skin remains comfortable, balanced, and visibly healthy between applications.
What truly distinguishes this serum is its commitment to both efficacy and purity, with 96% of its ingredients derived from natural origins. Enriched further with soothing Avène Thermal Spring Water, the formula works to rebalance and calm sensitive skin while providing its signature hydrating benefits. The addition of Propanediol, Diglycerin, and Pentylene Glycol creates a sophisticated humectant complex that attracts and seals in moisture at multiple levels, while Betaine and PCA contribute to the skin's natural moisturising factors. The result is a formula that not only hydrates deeply but actively supports the skin's long-term health and resilience, all delivered in a texture so light and refreshing that it feels like water on the skin.
To use, simply apply the serum morning and/or evening to a thoroughly cleansed face, neck, and décolleté. Dispense a small amount equivalent to a bead of cream and begin by toning the skin with gentle tapping motions to stimulate circulation and absorption. Then, smooth the product from the middle of the face outward using upward, sweeping movements, taking care not to forget the delicate neck area. For an invigorating finish, experts recommend a light cupping technique: place the flat part of your hands on your face and quickly remove them, repeating several times to stimulate microcirculation and enhance radiance. Whether used alone on warmer days or as a hydrating base beneath your favourite moisturiser, the Avène Hydrance Boost Serum offers dehydrated sensitive skin the long-lasting, comfortable quenching it deserves, restoring balance, softness, and a beautiful, healthy glow with every application.
How to Use:
Apply morning and/or evening to the face, neck and décolleté, by itself or following your serum.
An Expert Tip:
- Tone your skin by tapping the equivalent of a bead of cream on your face and neck.
- Smooth from the middle of the face outwards, without forgetting the neck.
- Stimulate with light cupping by placing the flat part of the hands on the face and quickly removing them.
