Aging and Skin Care

The document discusses various skin conditions associated with aging. It notes that skin is considered "aged" after 40 years and that men and women treat their skin differently due to biological and sociocultural factors. Men's skin, influenced by higher testosterone levels, tends to have more active sebaceous glands, while women's skin is often judged more on appearance. Skin care routines, dry skin, antiaging, reconstructive, and metaphysical aspects are mentioned as important considerations. The document also covers genital skin diseases in the elderly, which are common but often poorly managed, and highlights the importance of recognizing and treating conditions like lichen sclerosus and erosive lichen planus due to their pre-malignant potential. Changes in the nail plate with age are discussed, including physiological changes and increased incidence of disease, which can affect mobility and dexterity. Diseases of the hair and scalp in the elderly are also addressed, noting that aging affects hair density, cycle, structure, and pigmentation, with conditions like heliodermatosis and epithelial neoplasms being more severe in the presence of long-duration androgenic alopecia. Lastly, the document reviews cutaneous mycoses in the elderly, emphasizing the role of host defenses and the impact of predisposing factors like obesity and circulatory disorders, as well as the importance of prevention due to the increasing elderly population.
