Understanding Post-inflammatory Hyperpigmentation
Post-inflammatory hyperpigmentation means darker marks that remain after inflammation or injury, such as acne, eczema, scratching or a burn. The marks are usually flat and are not the same as a scar. They can be more noticeable and persistent in darker skin. Treating the original inflammation is an important first step.
Common symptoms
- Brown, grey or darker patches where a previous rash or injury occurred.
- Flat marks without the raised or indented texture of some scars.
- Slow fading, especially when inflammation or sun exposure continues.
Causes and contributing factors
Inflammation stimulates pigment production or changes where pigment sits in the skin. Picking, harsh products and poorly selected procedures can produce additional inflammation and worsen the marks.
How the condition is assessed
A clinician checks the preceding skin problem and the pattern of pigmentation. Not every dark spot is a post-inflammatory mark; an unexplained, changing or unevenly coloured lesion needs separate assessment.
Care and treatment considerations
Avoid picking, use gentle skincare and protect the area from sunlight. Control active acne, eczema or another cause before seeking a pigment procedure. A clinician may discuss topical options or carefully selected procedures; improvement takes time and no treatment guarantees complete clearing.
When to seek medical help
Arrange review for uncertain pigmentation, continuing inflammation or irritation from lightening products. A spot that grows, bleeds, changes shape or develops several colours needs prompt examination.
Patient questions
Are dark acne marks the same as acne scars?
No. Pigment changes are flat, while scars involve a change in skin structure. Both can occur together and may require different approaches.
Will a stronger peel clear the marks faster?
Not necessarily. Excess irritation can cause more pigmentation, particularly in darker skin. An individual assessment is safer than increasing product strength.
