REJURAN Biome Healer Touch Formula Sunscreen 50ml is used as the last step of your morning skincare routine. Apply a generous amount (two fingers’ worth of product) to the entire face, neck, and ears, 15 minutes before sun exposure. Gently pat to help the “touch formula” texture adhere to the skin, then wait a few moments before applying makeup. Reapply every 2 to 3 hours if exposure is prolonged.
