Topical zinc sulphate (25%) solution: A new therapy for actinic keratosis

Abstract

[...] the response was recorded as poor, partial or good response [Table 1]. [...] treatment period of 10 weeks is optimum for the treatment of actinic keratosis by 25% zinc sulphate solution. [11],[12],[13],[14],[15],[16],[17],[18],[19],[20] Reactive oxygen species have been implicated in the pathogenesis of various hyper proliferative and inflammatory diseases including actinic keratosis, and as zinc sulphate has antioxidants function to protect the skin from the harmful effect of free radicals, so zinc sulphate has antineoplastic action.
