The skin temperature decreases, especially among long-livers. This is due to a general decrease in metabolic processes, but partly due to the deterioration of blood supply and changes in sweat glands. Due to the decrease in their number, the excretory function of the skin is weakened (Khrisanfova, 1999).
Significant changes are happening to thehair. Starting from the age of 30, the density of hair on the skin decreases (the density is a number of hair on a surface unit), they turn gray, that is, they cease to be colored with pigment. One of the reasons for graying is that the cells of the hair follicles (melanocytes) lose the ability to form a dye pigment. However, it is expected that another, more important reason is violation of a process of pigment transfer from melanocytes to the growing hair (Prokhorov, 2015b). Although hair growth is declining, older women often have facial hair (on the upper lip and chin). At the same time, hair on the body, limbs and eyebrows may disappear after 60 years.
