Retinol for visible renewal — dosed at a tolerance the skin can keep.

Serenity Age is BIOSAR's anti-aging system for the visible signs of mature skin. Retinol accelerates the skin's renewal cycle and supports collagen, softening the look of fine lines and uneven texture while dosed for cosmetic-grade tolerance. Paired with peptides selected for documented signaling, and the SPF discipline that decides whether any retinoid actually delivers.

Key actives

3 hero ingredients

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

Retinol
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.
Peptides
Palmitoyl Tripeptide-1
Short chains of amino acids that act as messengers in the skin. In anti-aging formulas they support the signals behind firmness and elasticity, softening the look of fine lines for smoother, more resilient skin.
Resveratrol
Resveratrol
A polyphenol antioxidant from grape skin. It helps neutralize the free radicals behind dullness and environmental stress, so overnight skin looks defended, revived and more even by morning.
