Ingredient review
Dithiomethylbenzamide
INCI: Dithiomethylbenzamide
Dithiomethylbenzamide is a synthetic preservative booster with limited public research; it may help extend product shelf life but could cause irritation in sensitive individuals.
In plain English
Dithiomethylbenzamide is a lab-made chemical added to skincare products to help stop germs and mold from growing. It's not a main preservative but works alongside others to keep your product fresh. Because it's relatively new in cosmetics, there isn't a lot of independent safety data available yet, so it's best for people with resilient skin who aren't prone to reactions.
