Resveratrol, the next big anti-aging antioxidant?
Known for their anti-ageing properties, antioxidants are big news in the skincare world. We take a closer look at resveratrol – an antioxidant championed by experts for its oxidative stress-fighting abilities.
What is resveratrol and where is it found?
Resveratrol belongs to the polyphenol family of antioxidants, and is produced by plants in response to environmental stress. It has been identified in over 70 plant species and is found on the film of grape seeds. Polyphenol antioxidants are thought to reduce the visible signs of skin ageing by helping to fight the effects of UV-related stress.
How resveratrol helps the skin
With up to 80% of premature skin ageing linked to external factors such as UV damage, research suggests that resveratrol could have a positive effect on maintaining a youthful appearance. Resveratrol has been proven to help improve the skin by both protecting and fighting these external aggressors. First and foremost, resveratrol’s antioxidant properties have been shown, through test-tube experiments, to be particularly effective in fighting the effects of UV and pollution damage. Additionally, recent research conducted by L’Oréal found that resveratrol boosts skin’s existing antioxidant defences, improving its ability to respond to (and repair) signs of UV damage.
How best to use
Research has also shown that resveratrol is best applied onto the skin, rather than being consumed, as this allows it to penetrate the skin directly, instead of being used elsewhere in the body. This directly stimulates skin’s existing antioxidant defences!
Now you know a little more about antioxidants and the benefits of ingredients such as resveratrol, you can start to help protect your skin from urban ageing and oxidative stress. Vichy’s new Slow Âge Night Cream & Mask, enriched with 100% pure and natural resveratrol, works to re-oxygenate and help regenerate the skin while you sleep for a smooth, even, and radiant looking complexion by morning.
