Micronized
Micronized is a term used in the cosmetics industry to describe ingredients that have been ground down into extremely tiny particles. This process makes products like powders and sunscreens feel smoother on the skin and work better. When something is micronized, it means it's been processed to be so small that it's measured in microns (which are smaller than what the human eye can see). This is important in cosmetics because smaller particles usually mean better product performance, more even coverage, and a more luxurious feel on the skin.
