Multi-weight Hyaluronic Acid that hydrates at every skin depth. Ceramide complexes for the barrier underneath.

Hydraderm is BIOSAR's hydration system, formulated under dermatological supervision for dry and dehydrated skin. Hyaluronic Acid is dosed in multiple molecular weights to bind moisture at the surface, mid-dermis, and below. Ceramide complexes restore a barrier that has been compromised. Glycerin and Panthenol calm the tightness most pharmacy moisturisers leave behind.

Key actives

3 hero ingredients

Each Hydraderm product is built around these actives at concentrations supported by formulation dossiers.

Hyaluronic Acid
Sodium Hyaluronate
Humectant that binds many times its weight in water — one of the most effective hydrators available for topical use. BIOSAR formulates it as 8D Hyaluronic Acid: eight molecular weights working together, from higher weights that hold water and plump the surface to lower weights that carry hydration into the deeper stratum corneum, so one layer hydrates at several depths at once.
Ceramide
Ceramide NP
Skin-identical lipid. Rebuilds the barrier between corneocytes and restores comfort to dry, dehydrated skin.
Shea Butter
Butyrospermum Parkii (Shea) Butter
Rich plant butter with emollient fatty acids. Delivers lasting comfort on body, hands, feet, lips, and baby skin.
