Daily sun protection is essential for skin health, and getting the application right is the key to maximising your shield against harmful rays. Apply your sunscreen liberally to all exposed areas of your skin about 20 minutes before you step outside. Sun Hydrating Face SPF 50+ is water-resistant for up to four hours, but it's always a good idea to reapply every two hours, particularly if you're swimming, sweating, or using a towel to dry off. For optimal protection, combine sunscreen protection with UV-protective sunglasses, a wide-brimmed hat, and protective clothing.
