Quick answer. Perioral dermatitis is a red, bumpy rash that appears around the mouth, nose or eyes, often triggered by topical steroid creams and heavy skincare products. The single most important step is usually to stop the steroid or trigger, which can briefly worsen the rash before it settles, so this is best done with a doctor’s guidance.

Perioral dermatitis is a common facial rash that catches many people off guard, because the very creams used to calm it, particularly topical steroids, are often what keep it going. It shows up as clusters of small red bumps and scaly skin around the mouth, and sometimes around the nose or eyes, typically sparing a thin border right next to the lips.
In Singapore, where steroid creams are easy to obtain and elaborate skincare routines are popular, perioral dermatitis is something dermatologists see regularly. The condition is not dangerous, but it can be persistent and frustrating. The key to clearing it is recognising and stopping the triggers, especially topical steroids, rather than reaching for stronger creams. This guide explains how to recognise it, what causes it, and how it is treated.

What is perioral dermatitis?
Perioral dermatitis is an inflammatory rash of the facial skin, most often around the mouth (‘peri-oral’ means ‘around the mouth’). Despite the name, it can also affect the skin around the nose and the eyes, in which case it may be called periorificial dermatitis. A characteristic clue is that it usually leaves a clear, narrow strip of normal skin immediately bordering the lips.
It is most common in women aged roughly 20 to 45, though it can affect men and children too. It is benign and does not scar, but it tends to be stubborn and can take weeks to settle. In Singapore it is seen frequently, partly because of the widespread use of topical steroid creams, which are a leading trigger.
Symptoms & signs
Perioral dermatitis usually develops gradually and may come and go. Typical features include:
- Clusters of small red or skin-coloured bumps, sometimes with tiny pus-filled spots
- Mild scaling, flaking or dryness over the affected skin
- A burning, stinging or tight feeling rather than true itch
- A rash concentrated around the mouth, nose or eyes
- A spared rim of normal skin right next to the lips, which is a helpful clue
Unlike acne, there are no blackheads or whiteheads, and unlike eczema, intense itch is uncommon. The rash often flares when a topical steroid is stopped and improves only slowly afterwards.
Causes & risk factors
The exact cause is not fully understood, but several triggers are well recognised:
- Topical steroid creams on the face, whether prescribed or bought over the counter, are the most important trigger; they can improve the rash briefly but cause it to rebound and persist
- Heavy or occlusive moisturisers, cosmetics and sunscreens that trap the skin
- Some toothpastes, particularly fluoridated ones, in those affected around the mouth
- Inhaled or nasal steroid sprays in some people
- Hormonal changes and the use of certain cosmetic routines
Being a young or middle-aged adult woman raises the risk, but anyone can develop it. Identifying and removing the trigger is central to recovery.
How it's diagnosed
Perioral dermatitis is usually diagnosed clinically, meaning a doctor or dermatologist recognises it from its appearance, location and history. They will typically:
- Ask about your skincare and cosmetic products, and crucially about any use of steroid creams or sprays on or near the face
- Look for the typical small bumps with the spared border next to the lips
- Distinguish it from acne, rosacea and eczema, which look similar but are managed differently
Tests are rarely needed. Occasionally a skin swab or, very rarely, a small skin sample is taken if the diagnosis is unclear or the rash is not responding as expected.
Treatment options
The cornerstone of treatment is to stop topical steroids and other triggers on the face. This is so important that it bears repeating: continuing to apply steroid creams, even ones that seem to help in the moment, will usually keep perioral dermatitis going. Because stopping the steroid can cause a temporary flare-up before the skin settles, this is best done with a doctor guiding you, sometimes stepping the steroid down gradually.
Alongside stopping triggers, treatment may include:
- Simplifying your skincare routine, pausing heavy creams, make-up and unnecessary products (sometimes called ‘zero therapy’)
- Topical antibiotic or anti-inflammatory creams prescribed by a doctor
- A course of oral antibiotics (used for their anti-inflammatory effect) for more stubborn or widespread cases
Improvement is gradual and may take several weeks to a couple of months, so patience is needed. No expensive procedures are required, and the condition does not usually leave scars.
When to see a doctor & which specialist
It is worth seeing a doctor if you have a persistent bumpy rash around your mouth, nose or eyes, particularly if:
- You have been using a steroid cream on your face and the rash keeps returning or worsening
- The rash is spreading, very uncomfortable, or affecting your confidence
- You are not sure whether it is perioral dermatitis, acne, rosacea or eczema
Do not simply apply more steroid cream in the hope of calming it, as this usually backfires. A general practitioner can start treatment, and a dermatologist can confirm the diagnosis, guide you safely off steroids and manage stubborn or recurrent cases. Seek earlier review if the rash becomes acutely inflamed, painful or spreads to the eyes themselves, as eye involvement needs prompt assessment.
