20 Unexpected Culprits Provoking Your Atopic Dermatitis Flare-Ups

17. Saliva and Drool

It might sound strange, but for infants and even some adults, saliva is a surprisingly common irritant. Babies with atopic dermatitis often flare around the mouth, chin, or cheeks because of constant drooling. Saliva contains enzymes meant to break down food—but when left on the skin, it can also break down the skin barrier. Even pacifiers and thumb-sucking contribute. For adults, nighttime drooling during deep sleep can have a similar effect. Barrier creams, gentle face wipes, and regularly patting (not rubbing) skin dry can help. Keeping the area clean and protected is key—even from your own spit.

18. Friction from Masks and Glasses

Post-pandemic, face masks and glasses have become everyday essentials—but they come with friction. Constant rubbing on the bridge of the nose, ears, or cheeks can irritate sensitive skin and trap moisture, bacteria, or allergens. For people with atopic dermatitis, this repeated contact can trigger inflammation or even infection. Consider switching to silk-lined masks, adjusting fit for reduced rubbing, and applying a light barrier cream before wearing. For glasses, make sure they’re properly fitted and cleaned regularly—dirt and residue can add to the irritation. What protects your health shouldn’t compromise your skin—some small tweaks go a long way.
