Can perioral dermatitis affect the forehead?

Where can the rash appear?

The rash often starts in the folds beside the nose and spreads around the mouth. It can also reach the eyes and forehead. More extensive cases can involve the cheeks, eyelids and glabella, the area between the eyebrows. The broader name, periorificial dermatitis, describes involvement around facial openings rather than only the mouth.345

What does it look and feel like?

Typical features are clusters of small bumps with surrounding redness. The surface can be dry or scaly, and some bumps contain fluid or pus. Burning, itching and tightness can occur. Around the mouth, a narrow strip of skin immediately beside the lips often stays clear. Symptoms range from no discomfort to itching or burning, so a rash does not have to feel painful to warrant assessment.45

How is it different from acne?

Perioral dermatitis lacks blackheads and whiteheads, also called comedones. Deep nodules and cysts are not typical either. Those differences help a clinician distinguish it from acne, but the whole pattern matters more than one bump. Rosacea can cause central facial redness and similar breakouts, sometimes with stinging or gritty eyes. Seborrheic dermatitis can involve the forehead hairline and scalp, while contact dermatitis often causes more intense itching.1456

Arrange an assessment if the bumps persist or an apparent acne breakout is not responding to treatment. Diagnosis usually comes from examining the skin and reviewing your history. A clinician can also rule out contact dermatitis and seborrheic dermatitis rather than choosing a treatment from location alone.26

What should you do while waiting for an assessment?

1. 1Review your facial products and medicines. Steroid creams, nasal sprays and inhalers are associated with perioral dermatitis, as are some cosmetics and thick moisturizers.
2. 2Pause unnecessary facial cosmetics and creams. Wash with warm water alone while the rash is active rather than adding more products to treat each bump.
3. 3Avoid heavy, oily creams and ointments. If dryness needs treatment, a bland moisturizer without additives is an option; a gel or liquid sunscreen can be used.
4. 4Do not start an over the counter steroid cream for the rash. If you already use a prescribed facial steroid, ask the prescriber how to withdraw it.

Pausing unnecessary cosmetics leaves a shorter routine, with fewer marketing departments involved in your morning.7

Facial steroids can make the rash look better briefly but worsen it with continued use. Stopping a potent steroid abruptly can cause a rebound flare, so withdrawal sometimes needs a gradual plan. Continue medically necessary inhaled, nasal or oral steroids; rinsing the face and mouth after nasal or inhaled treatment can help.45

The exact cause is unknown. Fluoridated toothpaste is another proposed trigger, and changing dental products can form part of treatment. Discuss that possibility with your clinician rather than assuming toothpaste explains every forehead eruption.27

A stripped back cosmetics routine can mean buying nothing new, an unusual outcome for a skincare shopping list.4

What treatment helps, and how long does it take?

Doctors can prescribe topical antibiotics such as metronidazole or erythromycin, or oral antibiotics when needed. Sensitive facial skin sometimes does not tolerate topical treatment. Tell the prescriber if you are pregnant: erythromycin is an option used during pregnancy, and antibiotic selection needs to account for that.245

Treatment commonly lasts 4 to 8 weeks, but some courses extend to 6 to 12 weeks or several months. Without treatment, the rash can persist for months or years. Bumps can return after clearing, especially with renewed use of steroid creams. If treatment is not helping or the eruption returns, contact the prescriber to reassess the diagnosis and plan.467
