What to expect from topical antibiotic therapy for perioral dermatitis

Perioral dermatitis causes small bumps, redness, dryness, or burning around the mouth and sometimes near the nose or eyes. The skin can look more irritated before it becomes calmer, and improvement may be gradual rather than immediate. The medicine is intended to reduce inflammation and the factors contributing to the eruption; it is not a spot treatment to apply repeatedly throughout the day.

Steroid creams can temporarily hide facial redness and then make the eruption rebound or persist. If you use one, ask the prescriber how to stop safely rather than making an abrupt change on your own.

Apply a thin layer to clean, dry skin exactly as directed, avoiding the lips, eyes, and inside of the nose. Use lukewarm water and a mild, fragrance-free cleanser if needed. Pause scrubs, exfoliating acids, heavy occlusive creams, fragranced products, and unnecessary makeup while the skin is reactive. Do not add another antibiotic or steroid cream unless your clinician specifically recommends it.

Contact a clinician if burning, swelling, blistering, or scaling becomes marked, if the eyes are irritated, or if the rash spreads beyond the treated pattern. Seek prompt care for facial swelling with breathing difficulty or vision changes. Arrange reassessment when the rash does not begin settling in the expected timeframe, repeatedly returns, or becomes difficult to distinguish from another facial condition.

Ask how much product to apply, which cleanser and moisturiser are suitable, and whether any current steroid or cosmetic should be stopped. Clarify how to manage a flare after stopping steroid treatment, when makeup or sunscreen can be reintroduced, and what signs indicate irritation from the medicine.
