How to manage perioral dermatitis

Is the rash actually perioral dermatitis?

Perioral dermatitis is an inflammatory rash that usually causes clusters of small bumps around the mouth. The bumps can look red or skin coloured, with dry, flaky skin between them. Some people feel itching or burning; others have neither. The rash can also appear around the nose or eyes, when it is often called periorificial dermatitis, meaning dermatitis around an opening.1

On darker skin, bumps can also look purple or slightly darker than the surrounding skin, and redness can be harder to see. Pus filled spots are possible. The condition is more common in adult women, but children and men can develop it too. It is not contagious.134

Do not assume that bumps around the mouth are acne. Perioral dermatitis can resemble acne, but blackheads and whiteheads are not typical, and a narrow strip immediately beside the lips is often unaffected. A clinician usually diagnoses it by examining the rash and asking about your history. Contact dermatitis and rosacea can look similar and need different management.56

What should you change first?

1. 1Review any steroid cream used on your face. Stop hydrocortisone used without your doctor's knowledge, but ask the prescriber before changing a prescription steroid.
2. 2Pause facial cosmetics and unnecessary creams unless your clinician tells you to continue them.
3. 3Wash with warm water alone during the flare. If your treatment plan includes a cleanser, choose a mild, fragrance free one and wash gently.
4. 4Leave the bumps alone rather than picking or squeezing them.
5. 5Arrange a medical appointment if the bumps do not go away, so treatment matches the diagnosis.

Reducing facial products is part of treatment, not an invitation to buy the same routine again with calmer packaging. Mild cases can settle when unnecessary products and triggers are removed. More persistent cases need medication as well as changes to skincare.37

Why can steroid cream make it worse?

Steroid creams can temporarily calm the rash, then leave it flaring when you stop. Repeated use can make perioral dermatitis more severe and create a cycle of temporary relief followed by another flare. A worsening rash after withdrawal does not mean restarting the cream is the right solution. Your doctor can decide whether a gradual reduction is needed, especially after stronger facial steroids.4

A clinician sometimes uses a milder steroid briefly alongside other medication while managing withdrawal. That is different from using hydrocortisone repeatedly to suppress the rash yourself. Tell the clinician which steroid you used, how long you used it, and whether the rash worsens when you stop.14

Medically necessary inhaled, nasal and oral steroids should continue. They can lengthen recovery, but stopping treatment for another condition is not the answer. Rinsing your face and mouth after using an inhaler or nasal steroid can help reduce contact with the skin. Discuss your medicines with the prescriber rather than changing them yourself.7

Can you use moisturiser and sunscreen?

If dryness needs treatment, a bland moisturiser without fragrance or unnecessary additives is an option. Avoid thick, occlusive creams and ointments that form a heavy covering over the skin, because they can worsen perioral dermatitis. More cream is not automatically a better response to the tight, dry feeling.37

Sunscreen can be among the products that aggravate the rash, but a gel or liquid sunscreen is an option within a reduced routine. Ultraviolet light, heat and wind can also worsen perioral dermatitis. If your usual sunscreen irritates the area, discuss a suitable alternative rather than adding more products to compensate.67

After the rash clears, a soap substitute or mild cleanser can replace water alone, with an unperfumed moisturiser if your skin remains dry or sensitive. Cleansing does not require a matching collection, even if the bottles look disappointed about it.3

What about toothpaste and other triggers?

The exact cause is unknown. Facial steroids have a strong association with perioral dermatitis, while cosmetics, toothpaste and other exposures are possible triggers. Fluorinated dental products are worth discussing during your assessment, particularly if the rash persists. Hormonal influences, face masks and dental materials have also been associated with the condition; no single trigger explains every case.46

What treatments can a doctor prescribe?

Medication applied to the skin can help milder cases. Options include metronidazole, erythromycin and pimecrolimus, a nonsteroid medicine that reduces inflammation. Metronidazole 0.75% gel or cream is one treatment used twice daily. The prescription determines the formulation, amount and schedule; adding extra applications is not part of the plan.6

More severe disease, or a rash that does not respond to treatment applied to the skin, can need antibiotic tablets. Common options include doxycycline, minocycline, tetracycline and erythromycin. Antibiotics help reduce inflammation as well as bacteria. Treatment commonly lasts several weeks to a few months, and your clinician decides when to stop or extend the course.23

Pregnancy and age change the choice of antibiotic. Erythromycin is an option used for pregnant patients and children under eight rather than tetracycline treatment. Facial sensitivity can also make medicines applied to the skin difficult to tolerate. Tell your clinician if a prescribed product aggravates the rash so the treatment can be adjusted.7

How long does clearing take?

Expect gradual improvement rather than overnight clearing. The rash can take a few weeks or several months to clear completely. Some courses last six to twelve weeks, and longer treatment is sometimes needed. Follow the prescribed course rather than treating the first improvement as the finish. Bumps can return, especially if facial steroid creams are used again.12

When should you get medical help?

Book an appointment for bumps around the mouth that do not go away, or a rash that keeps returning. An unusual appearance or failure to respond can require further testing, including a skin biopsy. If the rash near your eyes comes with inflammation of the eyelids or the eye surface, seek assessment; rare forms can involve these areas and need an eye examination.24
