The outermost layer of a mask is the dirtiest part because it blocks viruses and bacteria. If you touch it directly, and then touch your eyes, nose, mouth, the virus will then enter the body.

What’s more, the solubility of propylene glycol is quite large, around 5% of people will have allergic reactions of it, so the long-term use will also hurt the skin.
