The skin is in constant interaction with the environment. Pollution, smoking, seasonal changes, lack of sleep and stress are all sources of aggression for our skin. However, exposure to the sun remains the primary factor in skin ageing and is responsible for 90% of wrinkles as well as premature skin ageing leading to the progressive alteration of the skin's natural hydrolipidic film. As well as with age, the body's collagen content decreases as production slows down, leading to sagging skin and wrinkles.
