What's New in Photoprotection?

It is well established that a complete package of photoprotection includes staying in the shade, wearing photoprotective clothing, hat, and sunglasses, and on otherwise exposed sites, applying sunscreen. Recent advances have modified photoprotection through new active ingredients, innovative formulations, complementary oral strategies, and personalized approaches. This review aims to summarize the latest new developments in photoprotection. A narrative review of the literature was conducted from January 2010 to October 2025 using terms related to photoprotection, sunscreen innovation, visible light, oral photoprotection, microbiome interaction, climate change, and personalized approaches. Articles in English and Spanish were selected based on scientific relevance. Advances in photoprotection include the development of new topical filters targeting UVA1 and visible light, as well as the incorporation of iron oxides and, in some formulations, pigmentary titanium dioxide in tinted sunscreens to enhance protection against visible light. In addition, the use of antioxidants and DNA repair enzymes has been explored to mitigate oxidative stress and address field cancerization. Natural and eco-friendly bioactive ingredients derived from botanical and marine sources show growing potential as photoprotective agents. Additional considerations such as the role of skin microbiome, and personalized photoprotection strategies tailored to skin phototype, lifestyle, diseases, and high-exposure conditions further refine preventive practice. Photoprotection is evolving into a multidimensional approach that integrates advanced topical formulations, oral agents, and individualized recommendations. This paradigm offers improved prevention of photoaging, pigmentary disorders, and photocarcinogenesis while promoting safer and more sustainable photoprotection practices.
