The Mineral Sunscreen SPF 30 PA+++ is designed as the last step in your skincare regimen. Let any previously applied products fully set before applying The Sunscreen. If you choose to apply makeup, wait few minutes before makeup application to avoid pilling. The Sunscreen SPF 30 PA+++ holds 20% Non-Nano Zinc Oxide and can pill if applied on top of thick formulations. A key tip: When you apply a mineral formula, spread a small amount evenly, then press gently into skin. Do not rub.
