What should you know about Tri-Luma for post-inflammatory hyperpigmentation?

Post-inflammatory hyperpigmentation is darkening that follows inflammation or injury. Acne and atopic dermatitis can leave marks after the active redness, spots, or itch settle, and darker skin tones may show colour change for longer. Tri-Luma combines hydroquinone, tretinoin, and a corticosteroid: these ingredients can reduce pigment production, encourage skin renewal, and calm inflammation. They do not remove the trigger, prevent every new mark, or suit every location. A clinician should confirm that the colour change is post-inflammatory before treatment.

Treat active acne, dermatitis, scratching, or another source of inflammation alongside the pigment concern. Use Tri-Luma exactly as prescribed on intact, dry skin and keep it away from eyes, lips, and skin folds unless directed otherwise. Use broad-spectrum sunscreen and reduce sun exposure; visible light can also deepen some marks. Avoid adding exfoliating acids, scrubs, bleaching creams, or other retinoids without advice. If irritation develops, contact the prescriber rather than increasing or extending use. Other options may include skin brightening treatment, chemical peel, or picosecond laser treatment after assessment.

Seek review for severe burning, swelling, blistering, persistent peeling, worsening darkness, pale patches, or a rash spreading beyond the treated area. Urgent care is needed for breathing difficulty or swelling of the lips or tongue. A mark that changes shape, bleeds, crusts, or fails to fit the pattern of prior inflammation needs examination before any lightening treatment. Pregnancy or breastfeeding should be discussed before use.

Is this truly post-inflammatory hyperpigmentation? What is causing the inflammation now? How long should treatment continue? Which skincare ingredients should I pause? How will we manage recurrence or residual uneven skin tone?
