A topical preparation designed to protect the skin from the harmful effects of solar radiation. These products typically contain organic and inorganic filters that absorb or reflect ultraviolet (UV) rays, thereby mitigating the risk of sunburn, premature aging, and skin cancer. For instance, formulations may include ingredients like zinc oxide, titanium dioxide, avobenzone, or octinoxate to provide broad-spectrum protection.
The widespread use of such preventative measures is crucial for public health, given the increasing incidence of skin cancer globally. Regular application, particularly during periods of intense sun exposure, can significantly reduce the cumulative UV damage to the skin. The historical development of these formulations reflects a growing awareness of the detrimental effects of UV radiation and advancements in cosmetic chemistry and dermatological research.
