Vitamin Deficiencies and Their Impact on Skin Function

Abstract

Vitamins are essential dietary items because of their functions as enzyme cofactors and catalysts in the body. Vitamin deficiency can significantly impact the skin, leading to a variety of dermatological problems, such as dryness, premature aging, hyperpigmentation, palmoplantar keratoderma, and even nail disorders. Alcoholism, rigid diets, inadequate parental nourishment, and intestinal absorption issues may all be factors in vitamin deficits. The most commonly deficient vitamins in relation to skin health are vitamin A, biotin, vitamin C, and vitamin D. Vitamin A helps to maintain the skin's barrier function and promote skin cell growth, while biotin helps to support the skin's underlying structure. Vitamin C is essential for collagen synthesis and skin brightening, and vitamin D is a crucial nutrient for overall health, including the skin. A balanced and varied diet and proper skin care can help prevent and address vitamin deficiencies, keeping the skin healthy and radiant. This review examines the most common vitamin deficiencies and their impact on the skin.
