Active ingredient
Isopropyl Isostearate
INCI · Isopropyl Isostearate
Isopropyl Isostearate is a lightweight emollient ester that improves spreadability. It gives formulas an easy, even glide and a smooth, non-greasy finish, helping creams and makeup lay down evenly and feel refined on the skin.
Mechanism in detail
What Isopropyl Isostearate does
Its low-viscosity ester structure thins the oil phase, easing spread for an even, smooth lay-down.
Where it helps
Concerns Isopropyl Isostearate addresses
Dryness
Dryness is a barrier dysfunction in which skin loses water faster than it can retain or replenish it, presenting as flaking, tightness, dullness, and roughness. Mild dryness reflects routine over-cleansing or environmental exposure; chronic dryness signals a deeper deficit in skin lipids (ceramides, cholesterol, fatty acids) and humectant content (the natural moisturising factor). Effective treatment hydrates and replenishes the barrier through three layered actions: humectants that draw water in, occlusives that seal it in, and barrier actives that rebuild the lipid mortar. The BIOSAR Hydraderm range delivers this layered hydration and visibly plumps dehydrated skin.
