What Is Dimethicone?

Dimethicone is a silcone-based polymer, which is frequently used in beauty products. It is used because of the smooth, even finish it provides on the skin. Perfect for the flawless looking base you expect from your makeup primers!

Is It Safe?

This is where the confusion often lies! Many think that Dimethicone blocks the skin not allowing it to breathe but this isn’t true! It actually provides a barrier which is breathable and also doesn’t let excess water escape.  Which means your skin will remain hydrated and the makeup you love keeps it’s non-comedogenic status.
