Be careful of these skin diseases in winter

Winter is cold and the air is dry, which can easily cause skin discomfort. The skin suffers strong cold stimulation, blood vessels constrict, the skin becomes dry, and the cuticle becomes thick and easy to peel. Extreme cold can also cause frostbite. Therefore, in winter, we should pay special attention to skin care. Different groups of people need scientific skin care according to their own characteristics. Today, dermatologists are here to take stock of the skin diseases that are most likely to cause trouble in winter.

Cracked heels

Cracked heels refer to dry and thickened heel skin, with cracks of varying depths and lengths appearing along the direction of the skin texture. When the crack deepens, varying degrees of pain may occur, the crack may bleed, or even become infected. Aging and lowering of temperature may increase the degree of heel cracking.

Cracked heels can be caused by physiological factors or pathological factors. With age, the skin thickens and lacks elasticity, and the foot sebum is secreted too little, resulting in dry and brittle skin; fungal infection of the foot leads to hyperkeratosis of the heel; diseases such as diabetes lead to dryness throughout the body; hereditary or acquired palmoplantar angle Chemical diseases, etc., may cause the problem of cracked heels.
