Abstract
Photoprotection is the primary preventive and therapeutic strategy against photoaging and skin cancer. This review presents the most important new advances in both topical and systemic photoprotection. Starting with innovations in the traditional physical and chemical filtering agents, we go on to discuss the growing number of antioxidants, the novel strategies for repairing light-induced DNA damage, and current research on substances that stimulate melanogenesis. A final section deals with protection against infrared radiation.

Resumen
La fotoprotección es una estrategia preventiva y terapéutica fundamental frente al fotoenvejecimiento y el cáncer de piel. Este artículo recopila las novedades más relevantes en sustancias fotoprotectoras, tanto en fotoprotección tópica como sistémica. Comenzando por las nuevas aportaciones a los clásicos filtros químicos y físicos, pasando por la creciente incorporación de sustancias antioxidantes, las novedosas estrategias de reparación del daño solar en el ADN y el estado actual del uso de sustancias estimulantes de la melanogénesis. Por último, se revisa la protección frente a la radiación infrarroja.
