Description

Sunscreens are cosmetic products for convenient and safe delivery of solar filters. These are used to prevent the skin damage caused by sunlight exposure. Due to photo-instability and potential adverse effects of some of these filters, novel application forms are demanded. Lipid based colloidal carriers commonly named as lipospheres provide the advantage of sufficient protection of the solar filters, their delivery to upper skin layer only, and controlled release. Being composed of biocompatible and biodegradable materials similar to those existing in the stratum corneum, they are generally well tolerated. This review gives an overview of novel approaches to sunscreen formulations.
