These rays release their energy into the skin, producing very harmful “free radicals”. This oxidation alters the skin’s cells and fibres. Cigarette smoke, alcohol and pollution are also aggravating factors. With age, the collagen fibres undergo glycation (action of sugars on proteins), making them rigid. In women, the menopause also speeds up the ageing process.

I recommend they use a broad-spectrum sun screen on their face, which protects the skin against UVAs. I talk about the benefits of stopping smoking. I encourage them to eat a healthy diet, rich in fruits and vegetables, to help fight free radicals. This advice is even more effective when followed before the first visible signs of ageing appear.

Depending on skin type and age, I recommend creams that contain antioxidant active ingredients that fight free radicals. They contain fruit acids, vitamin C or retinol. There are also creams that fight glycation to delay ageing. For women who are often outside, I recommend they use a day cream with a sunscreen from spring onwards.
