Post-inflammatory hyperpigmentation in skin of colour

PIH develops when inflammation stimulates melanin production or moves pigment deeper into the skin. It may follow acne, eczema, a bite, a burn, hair removal, or a cosmetic procedure. In deeper skin tones, the contrast can be especially visible and irritation from an overly strong treatment can create additional darkening. The patch is usually flat, but texture change, scale, pain, or a raised edge suggests that another process may be present.

Start by identifying and calming the trigger. Use a gentle cleanser, moisturiser, and broad-spectrum sunscreen on exposed skin; hats and clothing can add protection. Avoid picking, friction, and unregulated lightening products. A dermatologist can tailor a plan for your tone and history, explain patch testing, and discuss the condition in more detail through Post-Inflammatory Hyperpigmentation guidance. Treatment should be introduced gradually so irritation is recognised early.

Arrange a clinical review for a patch that changes quickly, bleeds, becomes painful or raised, develops scale, or appears without a clear inflammatory event. Seek urgent care for spreading redness, pus, fever, facial swelling, or breathing difficulty. A routine appointment can clarify the diagnosis before you try a peel, laser, or strong active ingredient.

Ask which trigger needs treatment, whether the pigment is superficial or deeper, how to prevent irritation, and how your skin tone changes the choice and intensity of any procedure.
