The Study
Natural Compounds with Antimicrobial Properties in Cosmetics
This study is like a teacher summarizing what other scientists have found about natural ingredients that can kill germs in makeup. It doesn’t do its own experiment, so it can’t prove anything new — it just tells us what others have seen in labs.
