Sunscreens should be used every morning and throughout the day during sun hours.  These mineral-based, chemical-free tinted moisturizer/sunscreens have broad-spectrum sun protection.  In addition to protecting from harmful UVA/UVB rays, antioxidants and other ingredients are used to rejuvenate the skin, rarely seen in other sunscreens.  Use every a.m. before makeup application to face, neck, and decollete.
