Perioral Dermatitis on Dark Skin: What to Know

The rash often sits around the mouth but may also involve the nose or eyes. On deeper skin tones, redness can be subtle or absent, while swelling, warmth, itching, tightness, or colour change may be easier to notice. Dark marks can remain after the active rash improves; this is post-inflammatory hyperpigmentation, not proof that the condition is worsening. It can resemble [Pimples](/symptoms/pimples/) or [Sensitive Skin](/symptoms/skin-sensitivity/), so a clinician may need to examine the pattern and your products.

Use a gentle cleanser, lukewarm water, and a plain moisturiser that does not sting. Pause scrubs, fragrance, essential oils, heavy occlusive creams, and new active ingredients near the rash. Do not start or stop a steroid cream without medical advice; [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) can temporarily mask the rash and may contribute to flares. A dermatologist may recommend [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/) or another treatment after confirming the diagnosis. Avoid picking, because irritation can deepen lingering marks.

Arrange a dermatology review if bumps, burning, or scaling persist, spread toward the eyes, or leave repeated dark marks. Seek prompt care for eye pain, light sensitivity, vision changes, marked facial swelling, pus, fever, or rapidly increasing tenderness. These features can signal another problem alongside the rash and need an examination.

Ask whether the pattern fits [Perioral Dermatitis](/conditions/perioral-dermatitis/), which products should be stopped, and how to protect your skin barrier while treating the flare. Ask how to distinguish active inflammation from leftover pigmentation and whether [Oral Antibiotics For Acne](/treatments/medical-dermatology/oral-antibiotics-for-acne/) is appropriate for your situation.
