Micronized zinc oxide
ZINSHADE contains micronized Zinc oxide which is one of only 17 active ingredients currently approved by the FDA for use in sunscreens. Upon application, zinc oxide particles sit on the outermost layer of skin, the stratum corneum, where they scatter, absorb, and reflect ultraviolet radiation, protecting living skin below. Zinc oxide is unique among sunscreen ingredients in that it is truly a broad-spectrum blocker, protecting from UVA, UVB, and even UVC. Titanium dioxide is another mineral active ingredient while it protects from UVB rays very well it does not protect from UVA as well as zinc oxide does. Zinc oxide is the safest, most effective active sunscreen ingredient available. It also stands alone in that it is a truly effective, single-ingredient, broad-spectrum blocker, meaning that it protects from UVA, UVB, and even UVC rays. Micronized zinc oxide protects against a wide range of UVA, including UVA 1 (340 to 400 nm). It is very photostable and does not react with other UV filters. It is more effective than titanium dioxide in regards to UVA protection.

MODE OF ACTION:
The mechanism of action of a physical sunscreen has its basis on the reflection and scattering of UV light in much the same way as clothing. The reflective properties determine the effectiveness of the sunscreens. These properties include the reflective index, the size of the particles, the film thickness, and the dispersion of base. The higher the reflective index, the better the UV filter decreasing the size of the particles to a micronized form (10 to 50 nm) is more cosmetically appealing but leads to the protection of shorter wavelengths and increases the risk of systemic absorption. A thick coating increases the degree of reflection but is cosmetically less appealing. Iron oxide can be an additive to increase absorption and improve UVA protection.
