When Is Chemical Peel Recommended for Post-Inflammatory Hyperpigmentation?

Post-inflammatory hyperpigmentation is a darker mark left after acne, eczema, an injury, or another inflammatory process. A peel can encourage shedding of pigmented surface cells, but irritation may deepen or extend the discoloration. For that reason, active acne, dermatitis, infection, scratching, or an unhealed wound should be addressed before cosmetic exfoliation.

The plan depends on the location, depth and colour of the marks, your baseline skin tone, and your history of pigment changes after procedures. A clinician may recommend a test area, a milder formula, or another approach when the risk of irritation is a concern.

Tell the clinician what caused the mark, whether the trigger is still active, and which creams, medicines, or procedures you use. Follow instructions about preparing the skin and avoiding tanning. Use the prescribed or recommended gentle cleanser, moisturiser, and broad-spectrum sunscreen after treatment.

Expect the treated area to feel tight or sensitive and possibly to shed surface skin, depending on the formulation. Avoid picking, scrubbing, waxing, or adding strong active products until the skin has recovered as advised. Improvement is usually assessed over time, and repeat treatment is not automatic.

Seek assessment before a peel if the area is inflamed, itchy, painful, crusted, oozing, or changing quickly. After treatment, contact the clinic for marked swelling, blistering, spreading redness, pus, fever, or pain that is getting worse. These signs can indicate a reaction or infection and need clinical advice.

Ask whether the original trigger is fully controlled, which peel strength fits your skin, how pigment risk will be reduced, what products to stop, and how long recovery may take. Ask what symptoms should prompt a call and what non-peel options are available.
