There are several types of electromagnetic radiation emitted by the sun. Unfortunately, although global use of sunscreen is continuously on the rise, so is the prevalence of malignant melanoma − a cancer type which is mainly caused by sun exposure,. Sunscreen application is the main strategy used to prevent the maladies inflicted by the sun since the 1930s. Taken together, this review advocates revisiting the current safety and regulation of specific sunscreens and investing in alternative UV protection technologies. In this review, data regarding the neurotoxicity of several organic filters: octyl methoxycinnamate, benzophenone-3 and −4, 4-methylbenzylidene camphor, 3-benzylidene camphor and octocrylene, and two allowed inorganic filters: zinc oxide and titanium dioxide, is presented and discussed. Reviews on the role of these agents in developmental and endocrine impairments (both pathology and related mechanisms) are based on both animal and human studies, yet information regarding the potential neurotoxicity of these agents is scant. Alongside the evidence for increasing levels of these agents in the environment, which leads to indirect exposure of wildlife and humans, recent studies suggest a toxicological nature for some of these agents. Physical filters scatter and reflect UV rays and chemical filters absorb those rays. In the past century, a variety of protective agents against UV exposure have been developed. Despite the continuously increasing frequency of sunscreen use worldwide, the prevalence of certain sun exposure-related pathologies, mainly malignant melanoma, is also on the rise. Sunscreen application is the main strategy used to prevent the maladies inflicted by ultraviolet (UV) radiation.
