Medicines for Perioral dermatitis
A bumpy, red rash that appears around the mouth — sparing the narrow border of skin next to the lips — and is often triggered or worsened by steroid creams used on the face, so the key step is stopping those creams.

Quick answer
What is Perioral dermatitis?
Perioral dermatitis is a common facial rash made up of small red or skin-coloured bumps, sometimes with fine scaling, that appears around the mouth. A characteristic clue is that it spares a narrow rim of skin immediately next to the lips, leaving a clear zone between the rash and the lip border.
- How it is treated: The single most important step in treating perioral dermatitis is stopping topical steroids on the face.
- Self-care: Simplifying your facial skin care is central to getting perioral dermatitis under control.
- When to seek help: See a pharmacist or GP if you develop a persistent bumpy red rash around your mouth, nose or eyes, especially if it is not settling after stopping steroid creams and simplifying your skin care, or if you are unsure what it is.
What it is
Perioral dermatitis is a common facial rash made up of small red or skin-coloured bumps, sometimes with fine scaling, that appears around the mouth. A characteristic clue is that it spares a narrow rim of skin immediately next to the lips, leaving a clear zone between the rash and the lip border. As well as around the mouth, it can affect the skin around the nose and, less often, around the eyes. It may feel tight, mildly itchy or burning rather than sore. It is most common in younger women but can affect men and children too. One of the most important things to understand about perioral dermatitis is its link with topical steroids: creams containing corticosteroids — whether used on the face deliberately, applied for another rash, or transferred from a steroid cream used elsewhere — are a well-recognised trigger, and the rash often flares when these creams are stopped before settling, which can tempt people to keep using them in a vicious cycle. Strong moisturisers and heavy face creams, as well as some cosmetics, can also play a part.
How it is treated
The single most important step in treating perioral dermatitis is stopping topical steroids on the face. Because these creams are a common trigger and keep the rash going, they need to be stopped — even though the rash may briefly flare for a week or two as they are withdrawn before it begins to improve. This temporary worsening is expected and is not a reason to restart the cream; persevering through it is key. This approach of simplifying skin care — stopping steroid creams and pausing heavy moisturisers and unnecessary cosmetics — is sometimes enough on its own for milder cases. When treatment is needed, antibiotics are the mainstay, used for their effect on inflammation rather than to fight an infection: a topical antibiotic such as metronidazole or erythromycin applied to the skin for milder cases, and an oral antibiotic such as a tetracycline taken by mouth for more widespread or persistent rashes. Treatment is usually continued for several weeks, and gentle skin care is kept up throughout.

Symptoms that can point to Perioral dermatitis
Perioral dermatitis can be one cause of these symptoms. Each guide explains the other possible causes and the red-flag warning signs that mean you should get urgent help:
Beyond medication
Lifestyle and self-care
Simplifying your facial skin care is central to getting perioral dermatitis under control. Stop using steroid creams on your face and resist the urge to reapply them when the rash flares as they are withdrawn — this flare is expected and settles. Pause heavy or rich moisturisers, occlusive ointments and unnecessary cosmetics, which can keep the rash going, and switch to gentle, fragrance-free cleansing with lukewarm water, using as few products on the face as possible while things settle. Avoid scrubbing or over-cleansing, which can irritate the skin further. Some people find toothpastes containing certain ingredients, or fluorinated products, seem to aggravate it, so it can be worth simplifying these too. Be patient and consistent, as the rash typically takes some weeks to clear, and try not to pick at the bumps.
When to get help
When to see a doctor
See a pharmacist or GP if you develop a persistent bumpy red rash around your mouth, nose or eyes, especially if it is not settling after stopping steroid creams and simplifying your skin care, or if you are unsure what it is. Mention any steroid creams you have used on your face or nearby skin, as this is an important part of the picture and helps guide treatment. Seek advice sooner if the rash is widespread, troublesome or affecting the skin around the eyes, or if it is causing significant distress, as a course of topical or oral antibiotic treatment under medical guidance may be needed to clear it.

Answers
Perioral dermatitis: frequently asked questions
What medicines are used for perioral dermatitis?
The most important step is not a medicine at all but stopping topical steroids on the face, as these commonly trigger and maintain the rash. When treatment is needed, antibiotics are the mainstay, used for their effect on inflammation rather than to fight an infection. A topical antibiotic applied to the skin, such as metronidazole or erythromycin, is used for milder cases, while an oral antibiotic such as a tetracycline taken by mouth is used for more widespread or persistent rashes. Treatment is usually continued for several weeks, alongside gentle, simplified skin care — pausing heavy moisturisers and unnecessary cosmetics — to give the skin the best chance to clear.
Why should I stop steroid creams on my face?
Topical steroid creams are one of the most common triggers for perioral dermatitis and tend to keep it going, so stopping them on the face is the single most important step in clearing the rash. The tricky part is that the rash often flares for a week or two as the steroid is withdrawn, which can tempt people to start using it again — relieving things briefly but trapping them in a cycle that prevents the rash from settling. This temporary worsening is expected and not a reason to restart the cream. Persevering through it, with gentle skin care and any antibiotic treatment advised, allows the skin to recover.
How can I tell perioral dermatitis from acne or rosacea?
There is overlap, which is why it is worth having a rash checked. A helpful clue to perioral dermatitis is its location — small red or skin-coloured bumps clustered around the mouth, often sparing a clear rim of skin next to the lips, and sometimes around the nose or eyes. Acne tends to involve blackheads and whiteheads as well as spots, over a wider area such as the forehead, cheeks and back. Rosacea typically causes flushing and redness with bumps mainly over the central face. Because the treatments differ, a pharmacist or GP can help confirm which it is and advise accordingly.
How long does perioral dermatitis take to clear?
Perioral dermatitis usually takes a number of weeks to clear, and it often gets a little worse before it gets better — particularly in the first week or two after stopping steroid creams. Antibiotic treatment, whether a topical antibiotic for milder cases or an oral one for more widespread rashes, is generally continued for several weeks to settle it fully and reduce the chance of it coming straight back. Patience and consistency are important: keep up the gentle, simplified skin care, avoid restarting steroid creams, and follow the treatment through rather than stopping at the first sign of improvement.
