A printable checklist for choosing and using sunscreen, including the PA rating used on Japanese products.

Read the label

SPF measures protection against UVB (burning) rays; dermatologists recommend SPF 30 or higher.
The PA rating (PA+ to PA++++) is a Japanese scale for UVA protection; more plus signs mean more UVA protection.
Look for broad-spectrum protection and water resistance if you swim or sweat.

Apply it right

Use enough: about a shot-glass amount for the body, and a generous amount for the face.
Apply about 15 minutes before going outside.
Reapply at least every 2 hours, and after swimming or sweating.

Buying from abroad

Products sold in Japan are regulated in Japan, not by the U.S. FDA; check ingredients if you have sensitive skin.
Patch-test new products before using them on your whole face.
