Dihydroxyacetone naphthoquinone protection against photosensitivity

Abstract

30 patients with multiple types of sunlight sensitivity were treated successfully with DHA/lawsone sunscreen. This sunscreen was able to protect all patients even though their photosensitivities were in different parts of the ultraviolet and visible spectrum. About 80% of the patients experienced sufficient protection during the summer months to lead a virtually normal life-style while participating in all kinds of outdoor activities.
