It is around the age of 50 that the biological condition of our skin alters, following hormonal changes associated with the menopause. The skin is less toned and hydrated, wrinkles are more pronounced and the epidermis is thinner. The problem lies with cell renewal, which diminishes appreciably at around age 50. This causes a drop in the production of collagen and elastin as well as a slowing down of the micro-circulation. This leads to a decreased input of nutrients essential to the vitality of cells, but also to a decrease of the colour component of the skin, the very same one that gives it a healthy look. Skin therefore becomes pale, almost transparent, and it loses its natural blush as the complexion fades.
