Active ingredient
Pentavitin
INCI · Saccharide Isomerate
Pentavitin is the trade name for Saccharide Isomerate, a moisture-binding saccharide that mirrors the skin's own carbohydrate complex. It is valued as a long-lasting humectant, anchoring moisture to the surface for enduring comfort and softness.
Mechanism in detail
What Pentavitin does
It binds to surface keratin and holds water in place, releasing only as the surface renews, for long-lasting moisture.
Where it helps
Concerns Pentavitin addresses
Aging
The first time you notice it is rarely a wrinkle. It is a quality of light — the way your skin catches it differently in a morning mirror, or the photo where you look more tired than you feel. The mechanism is real (collagen synthesis slows; elastin fragments; barrier turnover lengthens), but the felt experience comes first. Serenity Age is the range BIOSAR built for that pivot — Retinol for visible renewal and collagen support, peptides selected for documented signaling activity, and the SPF discipline that protects every other active you apply.
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.
