Bare Naked Face and Body Luminescence with SPF 30 4 oz. - A lighter and unscented version of our BARE Signature Body Butters, an unscented moisturizer with added zinc oxide for sun protection and light reflecting, complexion illuminating mica. What does mica do for your skin? Mica is a transparent mineral which is mined from the earth in thin sheets. It can be opalescent and sparkling or completely matte, ranging in color from grey to blue to green. It is often treated with iron oxides to yield brilliant color effects. Due to the sheer, translucent and skin-hugging effect of the mica mineral, your natural skin tone shines through. Mica powder, which reflects light creates an illusion of a smoother, softer and more radiant skin tone. Fine lines are softened by the light refractory properties of mica which counter the shadow effects of light. Without these shadows, which highlight wrinkles and imperfections, skin texture appears more even and more lucid.
