Fine lines and wrinkles are a natural result of aging. They are folds of skin and can generally be divided into two types – lines and deep wrinkles. They are most often formed in the areas that are most exposed to sunlight – face, neck, décolleté, arms. Some other factors can cause more pronounced wrinkles earlier: smoking, polluted air, diet, alcohol, stress.
Natural facial expressions also cause wrinkles – deep horizontal lines on the forehead, vertical folds between the eyebrows, and crow’s feet wrinkles around the eyes. Genes are also important for the formation of wrinkles – at the age of about 30, hereditary wrinkles and lines begin to appear in most patients because the synthesis of collagen and elastin, proteins responsible for the strength and flexibility of the skin, decreases with age. and the rate of cell division.
After 40, the facial muscles begin to weaken, as does the force with which they hold the skin, causing looser skin and the appearance of lines. The skin also becomes thinner and the areas around the chin lose fat, which can cause deeper wrinkles on the side of the chin.
