Sunscreen cosmetics as basic protection against photoaging

Abstract

The natural protective mechanisms of the skin indicate the harmful effects of sunlight, by the appearance of erythema and increased sweat secretion. The extremely unfavourable influence of solar radiation on the skin is the phenomenon of immunosuppression, which can lead to the formation of skin cancer foci. Effective sun protection delays skin photoaging, prevents sunburn and the formation of cancer. The available sun-protective preparations show increasing photostability. The aim of the work was to present fundamental issues in the field of sun protection and to explain the essence of the natural protective mechanisms of human skin. The article also explains the classification of sunscreen filters, divided into mineral (physical) and chemical ones.
