What is Photoprotection?
UV defense strategy beyond SPF
Photoprotection is the comprehensive strategy of protecting skin from UV damage. SPF is one layer; others include: antioxidant topicals (vitamin C + E + ferulic — the classic stack), iron oxides in tinted SPF (block visible light), physical barriers (hats, sunglasses, UPF clothing), behavioral (shade, avoiding peak UV hours), supplements (oral sunscreens like Polypodium Leucotomos). Daily SPF plus morning antioxidant serum plus reapplication is the evidence-based baseline.
