Drink two litres of water a day for healthy skinFALSE The amount of water you drink does not directly affect your skin. Water is supplied to the skin by blood flowing through the dermis, the inner layer of skin; water is lost from the epidermis, especially in a dry environment. Dermatologists use specific wavelengths of UVA and UVB in carefully controlled doses to reduce skin inflammation, a valuable treatment for some skin conditions. But when the skin is exposed to too much UV it can damage the skin cells’ DNA, leading to uncontrolled growth – the basis of cancer. Keep it simpleThe basic principles of keeping skin healthy are mainly common sense.
