Dry skin is a skin type characterized by a lack of oil or sebum production, leading to a tight, flaky, and sometimes itchy appearance. It can be caused by various factors such as genetics, aging, weather conditions, or overuse of harsh skincare products. To care for dry skin, it's essential to maintain a proper skincare routine that includes gentle cleansing, regular exfoliation, and moisturizing with a rich, hydrating cream or ointment. It's also important to avoid hot water and harsh soaps, as well as to stay hydrated by drinking plenty of water throughout the day. In some cases, using humidifiers at home and applying moisturizers immediately after bathing can help lock in moisture.
