How does skin appear with aging?

The distribution of lesions is heterogeneous according to the different parts of the body; thinning of the skin, especially by thinning of the dermis, the elastic fibers of which become scarce, and the collagen of which becomes rare and stiffens under the effect of glycosylation. The basal layer flattens out by reduction of the elastic fibers of the papillary dermis. Wrinkles appear with a decrease in the subcutaneous adipose tissue. The skin becomes dry, and the secretions of the sebaceous and sweat glands decrease. The hair follicles are less numerous and the melanocytes become scarce leading to the bleaching of hair and body hair. In addition, there are lesions related to exposure to solar radiation: elastosis, actinic keratosis, Dubreuilh's melanosis.
