Your skin is the largest organ in the body; it serves as a protective covering for your bones and internal organs. In addition, the skin also helps maintain body temperature. The outer layer of the skin known as the horny layer needs moisture to prevent dehydration, cracking, peeling and flaking. Dehydrated skin may also lead to premature aging.
Function
The skin is made up of three layers and weighs approximately 6 lbs. The outermost layer, the epidermis, continually sheds dead skin cells. The dermis is the middle layer of skin and is made up of lymph vessels, hair follicles, sweat glands and blood vessels. It contains receptors that allow you to feel pain. The dermis is held together by collagen, a protein. The deepest layer of the skin, the subcutaneous layer, is responsible for preserving the body's heat and acting as a shock absorber.
Causes
Dehydration of the skin may be caused by many factors. Harsh soaps and cleansers that contain alcohol may cause the skin to dehydrate. According to Healthy-Skin Care, dehydration of the skin may be caused by vomiting, high fever, diarrhea and not drinking enough water. Environmental factors such as cold weather and excessive sun exposure may also lead to skin dehydration.
Symptoms
Symptoms of dehydrated skin may include a tight feeling after bathing. There may be an itching sensation as well as flaky patches. Certain areas of the skin may develop cracks. Your skin will appear to lose smoothness, feeling rough to the touch. According to MayoClinic.com, skin that is dehydrated will shrivel and lack elasticity and will not bounce back when pinched.
Treatments
Treatment for dehydrated skin depends on the particular cause of the dehydration. If the dehydration is caused by vomiting, diarrhea or high fever, drinking water will restore the body's moisture. Skin dehydration caused by skin conditions may require a prescription from your dermatologist. Showers should be limited to once daily; avoid vigorous scrubbing with washcloths. Use oil-based moisturizing cream immediately after showering. In doing so, the moisture from the shower will get trapped in the skin and rehydrate it.
Warnings
If your skin dehydration symptoms persist after you have tried switching the soaps and cleansers that you use, consult your dermatologist. Excessive skin dehydration may be the result of underlying health or skin conditions such as psoriasis or eczema.
