Dry skin may cause itching and flaking, and can leave your skin feeling tight and uncomfortable. Healthy skin has a 10-20% water content. Flaky skin occurs when the protective natural oil produced by the skin begins to dry up. As a result, water loss in dry skin is 75 times greater than normal skin. As the skin loses both oil (sebum) and water, the skin begins to dry out and its topmost surface dies and begins to peel away, usually in very small, thin slivers called flakes.
Dry skin appears more often in the winter, but it can happen any time during the year and may be caused by a variety of factors, including hot baths and showers, harsh soaps, and sun exposure.
Either repair or remove flaky skin surface by gentle exfoliator followed by deep moisturization with topical creams.
