What the sources say about perioral dermatitis

Perioral dermatitis is a long-lasting inflammatory rash of the face. It causes stinging, burning or itching and small red bumps or pimple-like spots that can last for weeks to months. The skin around the mouth is most often affected, but it can also affect skin around the eyes and nose.
Peer-reviewed review, open access
About 90% of people with it are women between 20 and 45 years old.
Peer-reviewed review, open access
The cause is not clear. Heavy long-term use of facial creams, which can weaken the skin barrier, and fluoride toothpaste are suspected causes.
