Abstract
Sunscreens are formulations for skin application that contain substances that can absorb, reflect, or disperse solar radiation, reducing its biological effects on the skin (Schalka et al., An Bras Dermatol, 89:1–74, 2014; Schalka and Reis, An Bras Dermatol, 86:507–15, 2011). They are classified in organic or inorganic filters, based on their respective chemical compositions (Schalka et al., An Bras Dermatol, 89:1–74, 2014; Schalka and Reis, An Bras Dermatol, 86:507–15, 2011; Monteiro, Rev Bras Med, 67:5–18, 2010; Shaat, Sunscreens: regulation and commercial development, Taylor and Francis, Boca Raton, pp. 217–239, 2005). The main objective of this chapter is to differentiate the physical and chemical filters, their different galenical presentations, and their effectiveness.
