The insufficient UV photoprotection of approved sunscreens and the negative impact of their compositions on ecosystems and human health makes the utility of sunscreen questionable. Therefore, discovering UV filters with significant antioxidant activity and improved topical performance and photostability is crucial. The use of nanosized natural molecules incorporated in sunscreens has been a scientific hot topic, since they provide a synergistic effect with synthetic UV filters, improving overall SPF and antioxidant activity, higher epidermis retention, and less toxicity. Pedro Fonte from iBB and colleagues reviewed about formulations containing nanosized flavonoids with improved safety and UVA photoprotection becoming promising sunscreens.
