Skin ageing is a natural phenomenon leading to a loss of the skin's elasticity, the appearance of wrinkles and pigmented spots, particularly in uncovered areas. Nowadays, we can slow down these changes. A dermatologist's point of view.
How does ageing occur?
The skin ages when it is hit by UV rays.
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.
What advice do you give your patients?
Prevention is important: I advise them to moderate their sun exposure.
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.
What cosmetics do you recommend?
Daily moisturisation of the skin is essential.
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.
