What is flaky skin?
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. Flaky skin can be differentiated from a red rash with blisters or from scales (a raised, firm area that resembles fish scales) by the way it looks.
Cold weather contributes to flaky skin, as a combination of cold dry air outside and forced-air heat and lack of humidity inside combine to dry out the skin rapidly. However, flaky skin can also be a response to extended exposure to heat, such as in hot baths, heated swimming pools, hot tubs, and saunas. In addition, certain drugs, skin cleansers, and chemicals can dry out the skin and cause flaking. Finally, flaky skin is also a symptom of a number of specific disorders.
Flaky skin can sometimes resolve by itself or with appropriate moisturizing skin care. However, when flaky skin is caused by disease, it is important that you receive treatment for that underlying cause, in addition to changing your skin care regimen.
Dry, flaky skin can create an area of easy entry for bacteria into the skin. Seek prompt medical care if you have flaky skin and exhibit other symptoms, including cracks or breaks in your skin; red, swollen areas that are hot and tender; infected sores inside your mouth; unexpected joint stiffness and pain; blurred vision; genital sores; frequent fevers; excessive fatigue; unexplained weight loss; or frequent diarrhea. Seek immediate medical care (call 911) if an area that is hot, tender, red or swollen spreads rapidly to adjacent areas.
Seek prompt medical care if your flaky skin is persistent or causes you concern.
What other symptoms might occur with flaky skin?
