These hypoallergenic, non pore clogging natural minerals provide water-resistant SPF 30 sun protection to women and men alike. They are excellent for post-treatment use, especially on red or blotchy skin. Darker shades can be used as a bronzer. For best results, apply after moisturizer has completely absorbed into the skin. Reapply at least every 2 hours or reapply after 40 minutes of swimming or sweating and immediately after towel drying.
