As we get older, the skin cells' ability to produce the skin's building blocks decreases. The fibrous network of collagen and elastic fibers becomes weaker and more disorganized. The distribution of the water-binding structures changes and the skin's water content decreases, which becomes visible when the skin loses part of its volume. At the same time, the fat layer in the skin becomes thinner. Age-related changes in the skin are manifested, among other things, by the skin becoming flabby, wrinkled, less elastic and lacking in moisture. The first wrinkles start to develop from the end of the 20s. These are typical facial wrinkles, which occur when you use the muscles in your face, for example when you talk, smile or squint. From the age of 40, age-related changes become more noticeable. After menopause, the skin changes as a result of changing hormonal influences. The skin becomes thinner and less elastic, and wrinkles become more prominent. Men often get wrinkles a little later than women, but the wrinkles tend to be deeper. This is because men have thicker skin and higher sebum production than women.
