Wearing sunblock before applying any form of makeup is one of the most important untold rules. However, many are confused as to the level of SPF needed and amount to use. Here is the basic information you need to keep yourself safe and healthy under the sun.
SPF 30 is always the best way to go. According to most dermatologists, you should look for Zinc Oxide, Titanium Dioxide and Avobenzone in your sunblock for UVA and UVB protection. Although some foundations have SPF, it is still important to apply sunblock under your foundation for extra protection as a physical barrier. It is better safe than sorry!
It is also better to wait for a few minutes after applying sunblock to wear any makeup for thorough penetration into the skin. Here is a tip for you: try putting on a mask the day before to easily allow your skin to absorb the sunblock and be protected from the sun all day long.
