Zinc in dermatology

Abstract

Zinc has numerous pharmacological uses in dermatology. Its antioxidant and immunomodulatory properties are thought to correlate with its efficacy in acne vulgaris and leishmaniasis, amongst other cutaneous conditions. We conducted a review of the literature on the use of zinc in dermatology; in particular, we investigated its role in acne vulgaris, hair loss, hidradenitis suppurativa, leishmaniasis, and warts. We searched MEDLINE selecting only articles in English and evaluating the evidence using the Oxford Center of Evidence-Based Medicine 2011 guidance. This review has found evidence to support the use of zinc in patients in infectious conditions (leishmaniasis and warts), inflammatory conditions (acne rosacea, hidradenitis suppurativa) and in hair loss disorders.Ppatients with zinc deficiency should also receive oral supplementation. Further research and large randomized controlled trials are required to investigate the role of zinc as a monotherapy.
