Zinc therapy in dermatology: a review
Review of oral and topical zinc across acne, rosacea, wound healing, and other dermatologic endpoints.
A trace mineral your skin needs to repair itself. Almost every cellular process that touches a wound, a breakout, or a piece of collagen wants zinc at the table.
Why it's in Glowbite
* These statements have not been evaluated by the FDA.
Mechanism
Zinc is a cofactor for over 300 enzymes and a structural component of zinc-finger proteins that regulate gene expression. In skin, it's required for matrix-metalloproteinase activity (wound repair), superoxide-dismutase (antioxidant defense), and keratinocyte proliferation.*
Why this dose
30 mg is at the upper end of common daily supplementation; the US tolerable upper intake level is 40 mg/day for adults. If you already take a multivitamin with zinc, sum the total — chronic intake above 40 mg can interfere with copper absorption.

Interactions & cautions
Take separately from calcium, iron, and certain antibiotics (tetracyclines, fluoroquinolones). Long-term use without copper co-supplementation may reduce copper status in susceptible individuals.
