Targeted serums — a focused formula for each concern your skin raises.

Serenvit is BIOSAR's serum system — a focused library of targeted treatments, a lead active matched to each concern, working with the complementary actives around it. Hyaluronic Acid for hydration, Vitamin C and Tranexamic Acid for tone, Retinol for renewal, AHA and BHA for texture, Cica for comfort. Each serum is dosed for its own job and packaged in stability-led primary materials — opaque and airless — because active serums are fragile and the bottle is part of the formulation. The Retinol Serum is not for use during pregnancy or breastfeeding.

Each Serenvit 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.
Retinol
Vitamin A derivative. BIOSAR formulates it as Vitalize Retinol — a stabilised grade that shields the fragile molecule from light and air and releases it into skin gradually, so it supports the renewal cycle and refines the look of fine lines and smoother texture over time while staying kinder to comfort. Used at night, with daytime sunscreen; not recommended during pregnancy or lactation.
Vitamin C
Ascorbic Acid
Antioxidant that helps neutralize free radicals and supports a more radiant complexion. Contributes to the appearance of even tone over time.
