Rash Around the Mouth: Causes
While perioral dermatitis (also called periorificial dermatitis) may sound like technical jargon, it’s easy to understand once you break it down. Perioral means “near your mouth,” and dermatitis refers to a rash that is typically red, scaly, or bumpy in appearance.
This rash is not contagious but may be accompanied by itching, burning, or discomfort. It typically occurs around your mouth but can also affect other areas on your head, like your eyes, nose, neck, or scalp.
The exact cause of perioral dermatitis is unknown, but its risk factors may include:
- Use of topical steroids, inhaled steroids, facial moisturizer, fluoride toothpaste, and chewing gum
- Being female and between 25 to 45 years old
- Hormonal fluctuations and contraceptives
- Issues with microorganisms (like bacteria and pathogens), particularly in your skin or gut
- Immune disorders
Helpful tip: If your rash has yellow bumps instead of red bumps, this may indicate that your rash is a condition called granulomatous dermatitis, a condition that’s more common in children.
