Peeling fingers indicate a lack of what?

Peeling fingers can be caused by various factors, one of which is the deficiency of certain nutrients. Specifically, peeling fingers may be related to a lack of vitamins such as vitamin A, the B-complex vitamins, vitamin C, and vitamin E. These vitamins play important roles in maintaining skin health and promoting cell repair and metabolism. When the body lacks these vitamins, normal physiological functions of the skin may be affected, leading to peeling of the fingers. Additionally, peeling fingers may also be associated with deficiencies in trace elements such as zinc and iron, as well as protein. A lack of these nutrients can also affect the normal growth and metabolism of skin cells, thereby causing peeling symptoms. Besides nutrient deficiencies, finger peeling can also be caused by skin conditions such as eczema, tinea manuum (hand fungus), and dyshidrotic eczema (pompholyx), or due to prolonged contact with irritants or allergic reactions. Therefore, when symptoms of finger peeling occur, multiple factors should be considered comprehensively, and appropriate treatment measures should be taken.
