What to watch with Zink and Haut?

The question about zinc and skin is relevant because zinc is crucial for skin health, wound healing, and inflammation control. However, the provided context lacks specific genetic markers linking zinc directly to skin conditions. Known mechanisms: zinc deficiency can cause dermatitis, acne, and impaired healing; excess zinc (>40 mg/day long-term) risks copper deficiency and neurological issues. Some genetic variants (e.g., in SLC30A8, SLC39A8) affect zinc transport, but their clinical impact on skin is weak. Consumer DNA tests claiming 'zinc needs' are often overinterpreted. Recommendation: prioritize dietary zinc (oysters, meat, nuts); supplement only after checking status and consulting a doctor, especially for acne or slow wound healing. Evidence: mechanistic/unclear. Safety note: intranasal zinc can cause permanent anosmia.
