Active ingredient

Resveratrol

INCI · Resveratrol

Resveratrol is a stilbene polyphenol antioxidant used in skincare to neutralise reactive oxygen species and support visible firmness. It activates SIRT1-pathway gene expression, scavenges free radicals, and modulates UV-induced inflammation. Pairs well with vitamin C and ferulic acid for stacked antioxidant defence. No major conflicts.

Pregnancy and breastfeeding

No specific caution is known for cosmetic use during pregnancy or breastfeeding. If you are unsure, ask your doctor or pharmacist.

Topical cosmetic resveratrol delivers exposure well below the resveratrol content of routine dietary sources. Mother to Baby and Trivedi et al. (2017) flag no concern for topical cosmetic use during pregnancy or lactation.

Mechanism in detail

What Resveratrol does

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.

Evidence

What the research says

  • +18.9%Thicker eye-area skin on ultrasound after 12 weeks

    An open-label 12-week test of a night serum with resveratrol, baicalin and vitamin E: eye-area skin measured 18.9% thicker on ultrasound, and lines, firmness and elasticity improved against baseline. Three actives; no control group.

Where it helps

Concerns Resveratrol 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.

  • Dullness

    Dull skin is the visible loss of luminosity, where the surface appears flat, grey, or fatigued instead of light-reflective. The underlying causes are dead-cell accumulation on the stratum corneum, dehydration, microcirculation impairment, and oxidative stress. Effective treatment combines gentle exfoliation (alpha- and beta-hydroxy acids), antioxidant serums (vitamin C, niacinamide), barrier hydration, and consistent broad-spectrum SPF. Visible improvement typically arrives within two to four weeks of a structured routine, matching the natural cell-turnover cycle of healthy skin.
