Perioral dermatitis rings the mouth and nose and is usually triggered by the steroids and products used to treat it.

Key takeaways

• Perioral dermatitis causes bumps around the mouth or nose while sparing a clear strip at the lip border.
• Topical corticosteroids are the most common trigger and worsen the condition once stopped, a rebound effect.
• Simplifying the routine to a gentle cleanser only is usually the most effective first step.
• Prescription metronidazole, ivermectin cream or oral antibiotics speed resolution once triggers are removed.
