We highly recommend that our sunscreens are applied to the skin following the directions for use that are on the packaging. Any mixing of our sunscreens with any other product (e.g. makeup, moisturizers, serums, oils, etc.) may dilute the concentration of the mineral dispersion, as well as affect its film-forming ability, potentially reducing the SPF rating. As a result, you pose the risk of an uneven application and unpredictable protection for the skin.
When using makeup, apply your sunscreen first, and allow the product to dry for 2-3 minutes before applying foundation and/or color cosmetics.
