Abstract (EN): UV filters are the shield ingredients of sunscreens against the negative effects of solar radiation. Since the discovery of the first UV filter, nearly 30 filters have become commercially available. Over the years, innovation and regulatory updates have driven their use by the cosmetic industry. This work aimed to characterize commercial sunscreens and unveil the main trends by analyzing the labels of 444 sunscreen formulations that are currently being marketed. Avobenzone, octocrylene, and bis-ethylhexyloxyphenol methoxyphenyl triazine were the three UV filters with the highest usage frequencies (>40%). Emulsified preparations and sprays were the preferred forms, while the most frequent SPF was 50+. Differences were noted between adult and children's sunscreens, namely the higher usage of inorganic filters for the latter. Over the past few years, the five most used UV filters remained the same, but octocrylene, ethylhexyl salicylate, and nano methylene bis-benzotriazolyl tetramethylbutylphenol had decreased usage. An increasing tendency towards the use of the inorganic UV filter titanium oxide was also observed. Overall, this study characterized the true market impact of approved UV filters and how the market has evolved over recent years. This insight can help pave the way for the design of new UV filters and is helpful for the assessment of environmental risks.
