Your Official Sun Care Cheat Sheet

Notice how SPF only refers to UVB rays? After realizing we also need to protect our skin against UVA rays, a new system was developed. Developed in Japan, the PA system represents how much a product protects from UVA rays. The rating system isn't perfect, but it's helpful to know how much oomph your sunscreen carries. Basically, PA+ offers some protection, PA++ promises moderate protection, PA+++ delivers high protection and PA++++ provides extremely high protection.
