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.

Suncare has always fallen into one of two categories: a vacation product that you don't trust or a mineral/clinical solution that you don't love – never high-performance, skin-first suncare with protection and recovery that you want to use every day.
Whatever the day brings, life in the sun shouldn't feel like a compromise. SONNI is here to make sure it doesn't.
