title: Physical sunscreens: on the comeback trail.
abstract: Awareness of ultraviolet radiation-induced skin damage creates the need for the development of broad-spectrum, safe and cosmetically acceptable sunscreens. Being relatively inert, safe, stable and non-irritating, physical sunscreens are particularly useful for patients with sensitive skin who cannot tolerate chemical sunscreens. However, they form a thick visible pigment layer on the skin. To overcome this drawback, microfine oxides have been developed which made the sunscreens virtually transparent when applied on the skin. This article reviews the rationale for the comeback of physical sunscreens by analyzing data from various sources.
