Hello, after reading the information in order to make sunscreen, please ask a few questions. 1. Sunscreen should not be used as micronized
Zinc Oxide or micronized
Titanium Dioxide right? I read some research in some websites saying that it can penetrate into the skin, right? 2. The details that say
Zinc Oxide Micronized "Not suitable for use in sunscreen that requires high dispersion for good sun protection performance" Why is it Micronized and why is the dispersion lower than Non Nano
Zinc Oxide performance of
Zinc Oxide Micronized micronized
Titanium Dioxide It is less than Non Nano
Zinc Oxide Non Nano
Titanium Dioxide or not 4. In Thailand, there is still no use of non nano sunscreen at all, the main reason is because my face will be white, so I have to mix Microzied or not? Thanks in advance for your answer.
