How to use
How to use
Shake well before use. Apply 15 minutes before sun exposure. Reapply every two hours, or after 80 minutes of swimming or sweating. Rub in well (mineral-based SPF takes a moment to sink in). Pro tip: use as the last step in your skincare routine or as a priming layer under makeup.
