What to expect from a chemical peel for post-inflammatory hyperpigmentation

Post-inflammatory hyperpigmentation is a dark mark that follows inflammation or injury, including acne, eczema, burns, or irritation. A peel can help shed pigment-containing surface cells, but active inflammation must be controlled first. Treating irritated skin too soon can prolong inflammation and deepen the mark. The clinician also considers whether pigment sits near the surface or deeper in the skin, because deeper colour often changes more slowly.

Before treatment, describe the original rash or injury, current breakouts, recent procedures, tanning, and products that sting. Use the preparation recommended for your skin rather than adding extra exfoliants. After the peel, keep the area moisturised, avoid scratching or picking, and protect it from sunlight and visible light as advised. Temporary warmth, redness, dryness, or flaking may occur. Continue the plan for the original trigger, such as acne or eczema, because new inflammation can create additional marks. Several appointments may be discussed when pigment is extensive or persistent.

Contact the clinic if discomfort is severe or worsening, or if you develop blisters, open sores, spreading redness, pus, or swelling. Seek prompt assessment for a fever with skin changes or eye symptoms after treatment near the face. A mark that changes shape, bleeds, or does not fit the prior pattern of inflammation should be reviewed rather than repeatedly peeled.

Ask whether the original inflammation is sufficiently quiet, which peel is suitable for your skin tone, how to prevent rebound darkening, and which products to stop or restart. Discuss realistic colour change, the care plan between visits, and alternatives if your skin is too reactive for a peel.
