Vine polyphenols: natural allies to preserve youthful skin

Root Polyphenols: Brightening and Evening Skin Tone

Vine roots are rich in polyphenols called vitisins A and B (viniferin R2 and R1). These molecules have been clinically shown to reduce the appearance of dark spots by inhibiting tyrosinase, the enzyme responsible for melanin production. The result: a more even complexion, visibly brighter skin, and reduced irregularities caused by sun exposure. Discover our Hand and Nail Cream.

Grape Polyphenols in the Fruit: Protective Proanthocyanidins and Tannins

Inside grapes—especially in the seeds and skins—lie powerful polyphenols such as tannins and proanthocyanidins, particularly abundant in red varietals like Syrah, Grenache, or Mourvèdre. These compounds are distinguished by their potent antioxidant effects, which help slow down skin aging. Among them, catechin plays a vital role: it helps protect the skin from harmful UV rays while preserving DNA integrity. By reducing oxidative sun damage, catechin contributes directly to long-lasting anti-aging protection. Discover GSM10®.
