These ingredients primarily work by absorbing UV rays but also through reflection and refraction.Chemical sunscreens (also referred to as organic sunscreens), which use organic molecules as active ingredients. Chemical sunscreen ingredients work by absorbing the UV rays.Additionally, particulate organic UV filters, such asbisoctrizole, can also reflect and scatter a small portion of incident UV light.Hybrid sunscreens, which contain a combination of organic and inorganic UV filters. Medical organizations such as theAmerican Cancer Societyrecommend the use of sunscreen because it aids in the prevention ofsquamous cell carcinomas.The routine use of sunscreens may also reduce the risk ofmelanoma.To effectively protect against all the potential damages of UV light, the use of broad-spectrum sunscreens (covering bothUVAandUVBradiation) has been recommended.
