1. What is perioral dermatitis?
Perioral dermatitis is an inflammatory skin condition that causes clusters of small red bumps, papules, or pustules around the mouth. It most commonly affects the skin around the lips but can also involve the chin, nose, and sometimes the area around the eyes. The skin immediately next to the lips is usually spared.
2. What causes perioral dermatitis?
The exact cause is not fully understood, but it is strongly associated with the use of topical corticosteroid creams on the face. Other contributing factors include heavy facial moisturisers, cosmetic products, fluoride toothpaste, hormonal changes, and disruption of the normal skin barrier or microbiome.
3. Who is most likely to get perioral dermatitis?
Perioral dermatitis is most common in adult women aged 20 to 45 years, but it can also affect men and children. It is more likely to occur in people who use topical steroid creams, inhaled steroids without proper face washing, or multiple facial skincare products.
4. What does perioral dermatitis look like?
It typically appears as small red or flesh-coloured bumps, sometimes with mild scaling or dryness. The rash may feel itchy, tight, or burning rather than painful. Unlike acne, it usually does not contain blackheads or deep cysts.
5. How is perioral dermatitis different from acne or rosacea?
Perioral dermatitis lacks blackheads, which helps distinguish it from acne. Compared with rosacea, it is more localised around the mouth and is often triggered by topical steroids. Rosacea usually involves flushing and central facial redness, whereas perioral dermatitis presents with clustered bumps and minimal flushing.
6. How is perioral dermatitis treated?
The first step in treatment is stopping topical steroid creams, although this may initially cause a temporary flare. Treatment often includes topical antibiotics such as metronidazole or erythromycin, or oral antibiotics like doxycycline for more persistent cases. Gentle skincare and avoidance of irritating products are essential.
7. Should topical steroid creams be stopped suddenly?
In mild cases, topical steroids are usually stopped completely. In more severe or long-term steroid use, a gradual reduction under medical guidance may be recommended to reduce rebound flaring. This process should be supervised by a GP or dermatologist.
8. How long does it take to improve?
Improvement is usually seen within two to four weeks once appropriate treatment begins, but complete resolution can take six to twelve weeks. Temporary worsening after stopping steroids is common and does not mean treatment is failing.
9. Can perioral dermatitis come back?
Yes, recurrence is possible, particularly if topical steroids or heavy cosmetic products are reintroduced. Using gentle, non-comedogenic skincare and avoiding unnecessary steroid use on the face helps reduce the risk of recurrence.
10. When should I seek medical advice?
You should see a GP or dermatologist if the rash is persistent, worsening, or recurrent, or if you have been using topical steroids on your face. Medical review is also important if the diagnosis is uncertain or if symptoms are affecting your confidence or quality of life.
