‘Maskne’ Is a Thing — Here's How to Fight Face Mask Breakouts.
Wear only clean masks:
Dirt, oil and make up from your skin plus bacteria from your mouth and nose will end up on your cloth mask. Keep a rotation of masks on hand and wash them after every use.
A lot of laundry detergents contain pore-clogging ingredients or fragrances that will cause you to breakout. This waxy residue can cling onto your skin, causing acne. Look for enzyme and fragrance-free detergents.
Try to avoid Fabric softener and dryer sheets which can cause itchy, irritant reactions.
