Dry skin can be very unpleasant. If you have dry skin, you are more likely to have other skin problems such as wounds and acne. Your skin might also itch or become flaky, gray, or dull, or you might develop wrinkles or eczema.
Dry skin can be caused by a variety of factors. For example, warm water (especially hot water) and soap can have a huge influence because they remove your skin’s natural layer of fat. Your body repairs this itself by producing sebum, but this isn’t always enough. Sebum production varies from person to person, and it decreases as you get older.
