A physical barrier between you and the sun. Invisible Zinc protects against surface UVB and deeper penetrating UVA. Invisible Zinc uses only one active ingredient -Zinc Oxide- a mineral reflector found in nature to create a physical, reflective veil on the surface of your skin. Invisible Zinc uses micro-fine Zinc Oxide which although invisible to the naked eye still provides outstanding broad spectrum protection against UVA and UVB rays. True broad spectrum – offers consistent broad spectrum protection against UV(B) and UV(A) rays. Invisible Zinc doesn’t break down in the sun. Invisible Zinc means natural sun protection without skin whitening. Zinc Oxide has a long history of safe use in skin care products and is currently a key ingredient in many baby creams, calamine lotions and skin salves.
