Dehydrated skin is often confused with dry skin type therefore it is important to know the difference between the two. Dehydrated skin develops because of increased water loss from the superficial layers of skin, whereas, dry skin develops due to deficiency or under secretion of skin lipids/sebum/oil as a result of which the skin becomes excessively permeable. Dehydrated skin can be a result of using harsh face washes, excessive pollution, excessive use of air-conditioners etc.
Dehydrated skin is not a skin type it is merely a skin condition hence any skin type can become dehydrated.
To cure dehydrated skin use quality grade moisturizers having silicone, hyluronic acid, squalene and humectants like glycerine, honey, aloe vera.
