6. Face masks also need to be used correctly
In order for a mask to be effective, it should be placed to cover both your mouth and your nose, not just one or the other, says Dr. Schaffner. They also don’t work if you lift them up to talk to someone or to scratch an itch. They’re also not intended to be used if you have facial hair, says Dr. McGinty.
Important: Wash your hands with soap and water before using a mask and make sure there are no gaps between it and your skin. Also, you should avoid touching it with your hands while you are using it. When you remove the mask, don’t touch the front of it—remove it from behind, throw it immediately in a closed bin. After that, wash your hands with soap and water (or an alcohol-based rub if you don’t have soap and water).
