Mineral Sunblock - Zinc oxide
Zinc oxide is broad spectrum, it blocks UVA & UVB light, zinc is less whitening on the skin and blocks nearly all dangerous UV light. Inexpensive versions of these sunscreens are gooey, and even though they are used, most people don’t enjoy using them.
Newer Zinc oxide sunscreen contains particles so small that they are almost transparent. These sunscreens are called micronized and protect against UV light perfectly.
