Relationship between Hormones and Pigmentation
One of the most important factors involved in the initiation of aging is the endocrine system. Particularly important for women, the endocrine system produces and regulates hormones, which decline, sometimes drastically, with age. Hormones are chemical messengers that are produced in organs. A decrease in those can cause deep wrinkling, intrinsic skin aging and etc. Dryness, fine wrinkling and paleness is all part of the natural process of skin aging. Many factors are involved in intrinsic skin aging: genetic mutations, increased inflammatory signals, decreased lipid production and decreased hormone levels. These hormone changes are now being more closely examined to reveal just how important they are to skin health, especially in women.
Chloasma describes skin discolorations caused by hormones.
