ESK Hydraboost HA Serum is a lightweight hydrating serum formulated to replenish moisture, support the skin barrier and improve overall skin hydration. Suitable for all skin types, including sensitive, reactive, eczema and rosacea-prone skin, it combines three molecular weights of hyaluronic acid with panthenol (provitamin B5) to provide multi-level hydration while helping to maintain a healthy skin barrier.

The formula in ESK Hydraboost HA Serum contains high, medium and low molecular weight hyaluronic acid to deliver hydration throughout the upper layers of the skin. High molecular weight hyaluronic acid helps form a protective moisture layer on the skin’s surface, while the lower molecular weight forms help improve hydration within the skin barrier. Panthenol complements the formula by helping to support the skin barrier and maintain moisture levels.

This potent hyaluronic acid hydrating serum has a skin-friendly pH of approximately 5.0–5.5 and is suitable for daily use. Its lightweight texture absorbs quickly without leaving the skin feeling sticky or greasy, making it an ideal first step after cleansing before applying treatment serums and moisturiser.
