Apply generously and evenly to the facial skin before sun exposure, ensuring complete coverage of all exposed areas. Reapply frequently every 2-3 hours, especially after swimming, heavy perspiration or toweling, to maintain the original protection. Allow the product to fully absorb after application, avoiding direct contact with textiles and hard surfaces to prevent staining. Reducing the amount used will significantly lower the sun protection level, so do not use less than the recommended dosage.
