Sunscreen products typically contain active ingredients to protect human skin from UV radiation, such as organic compounds that absorb UV rays (e.g. cinnamates, camphor derivatives, benzophenones) and/or inorganic compounds (e.g. TiO2and ZnO), which act as chemical or physical filters preventing...
They are often referred to as ‘physical’ filters, as compared with ‘chemical’ filters, which are organic compounds. There is a common misconception that inorganic filters only reflect, scatter and refract sunlight, and as such are safer to our skin than organic filters. ...
