Introduction: Photoprotectors are the active ingredients of sunscreens with the capability of protecting the skin against UV radiation. An increasing number of such photoprotection ingredients have been launched in the marketplace, causing sunscreens' formulas to become increasingly varied. Objective: To list the main active photoprotection ingredients contained in formulations commercially available in Brazil, as well as to document the presence of other ingredients contained in sunscreens. Methods: The authors inspected four drugstores in the city of Rio de Janeiro, Brazil, and analyzed the formulas of the SPF 30 sunscreens available. The active photoprotector substances found in all formulations were listed and the percentage of each of them was compared to those contained in all sunscreens evaluated. The presence of plant extracts and antioxidants was also documented. Results: Thirty commercially available SPF 30 sunscreens were found in different drugstores, having their formulas analyzed. Within this sample, there were 17 different active photoprotection principles, of which titanium dioxide was the most frequently found, followed by bis-ethylhexyloxyphenol methoxyphenyl triazine. Conclusion: The present study lists the profiles of photoprotection active principles found in the main sunscreens on sale in Brazil and provides data for further evaluation of changes in these profiles over time, as new sunscreens are launched in the marketplace.
