How to use

Shake well before use. Apply 15 minutes before sun exposure. Rub in thoroughly (mineral SPF takes a few extra seconds to fully absorb). Reapply every two hours, or after 80 minutes of swimming or sweating. Best as the final step in your skincare routine. Allow to fully set before applying makeup.
