Wine

Wine is a fermented plant extract derived from grapes. During fermentation, yeasts and bacteria break down sugars and other compounds, creating a complex mixture of polyphenols, organic acids, and other bioactive constituents. In skincare formulations, wine is used primarily as a skin conditioning agent.The ingredient appears in cosmetics for its potential to hydrate and improve skin texture, though the specific active compounds responsible for these effects vary depending on the wine source, fermentation method, and concentration used.

Wine functions primarily through its humectant and emollient properties, helping to draw moisture into the skin and improve hydration. The polyphenols present in wine, such as resveratrol and tannins, have antioxidant characteristics that theoretically help neutralise free radicals on the skin surface.The organic acids naturally present in wine—including tartaric acid—may also provide gentle exfoliating action by loosening surface dead skin cells. The overall conditioning effect comes from the combination of these components working together to improve skin hydration and texture.

Wine-containing products can typically be incorporated into daily skincare routines. If using a product with wine as a featured ingredient, apply it after cleansing and before heavier creams or oils. Start with consistent use for several weeks to assess any benefit, as conditioning effects build gradually with repeated application.

Wine is generally well-tolerated in skincare formulations and is not known to pose safety concerns at typical cosmetic concentrations. Those with sensitivity to alcohol or fermented ingredients should patch-test first.
