Usage

Apply liberally and evenly to clean, dry skin 15 minutes before sun exposure. Reapply at least every 2 hours, and after swimming, sweating, or towel drying.

For best results:

  • Use a generous amount — most people under-apply
  • Rub in until fully absorbed
  • Reapply more often during peak sun hours
