Whether zinc is useful for skin depends on context. Zinc is an essential trace mineral that acts as a cofactor for enzymes involved in cell proliferation, wound healing, and inflammation control. In cases of confirmed deficiency – for example in acne, eczema, or psoriasis – supplementation can improve symptoms. However, the evidence is mixed: some randomized trials show benefit for inflammatory acne, but for the general healthy population, preventive effects are not well established. Bioavailability varies among supplements, and excessive intake can cause copper deficiency, nausea, and immune dysfunction. The MyBody-X knowledge context does not provide specific data on zinc and skin, so this answer relies on general physiological and clinical evidence. The evidence level is mechanistic to moderate – zinc is not a miracle cure but can be useful when targeted. Always consult a doctor or dermatologist before starting supplements for skin issues.
