Any mineral makeup powder
containing zinc oxide and/ or titanium dioxide offers natural protection from
the sun. Many natural sunscreen brands use these exact minerals in their
lotion formulations! However, as per FDA regulations, extensive (and
expensive) testing must be done for any product claiming to have a specific
level of SPF. Therefore, we recommend you use your own SPF product that
you feel comfortable with before applying minerals if you want to be assured of
your level of sun protection.
