Post-Inflammatory Hyperpigmentation After Acne: Clearing the Marks Left Behind
Quick Answer: PIH — the flat brown-to-dark marks where pimples used to be — is melanin deposited during inflammation, and it clears with a two-front protocol: stop the supply (treat the active acne — non-negotiable first step) and clear the archive (brightening topicals, salicylic-mandelic peel series, laser toning for the stubborn tier): 8–16 weeks, ₹3,000–₹8,000 per clinic session. Distinguish it from scars (texture change) — different problem, different tools, commonly co-existing.
Marks vs Scars: The Fingertip Test
Run a fingertip across the area with eyes closed: flat but discoloured → PIH (this article — pigment problem, excellent prognosis). Dented, pitted, or raised → true scarring (texture problem — MNRF/microneedling/subcision territory, flagged in the bonus cluster and Dr Rohit's acne hub). Most post-acne faces carry both; protocols run pigment-and-texture tracks in parallel, but conflating them is why "scar creams" disappoint PIH and peels disappoint pits.
The Two-Front Protocol
Front one — stop the supply. Every active pimple is a PIH factory; treating marks while acne continues is bailing a leaking boat. Acne control (Dr Rohit's medical hub owns this) comes first or alongside — always. The adjacent supply line: picking. Squeezed lesions inflame deeper and mark darker — the single highest-yield behavioural prescription in this article is hands-off, and every dermatologist will say it less politely. Front two — clear the archive. Prescription brightening routine daily (the engine), salicylic-mandelic peels fortnightly (the acne-friendly peel family — exfoliating marks while managing oil), laser toning for plateau residues at week 8+, and SPF throughout (UV re-darkens healing marks faster than fresh skin — the marks you're clearing are photosensitive).
Timeline Honesty
Fresh red-brown marks (weeks old): often clear substantially in 6–10 weeks. Established brown marks (months old): the 8–16 week protocol. Deep dermal-deposited marks (years old, slate-grey tone): the toning lane, longer horizons, honest floors. The universal accelerant: earlier treatment — which converts to the practical rule: start the marks protocol while finishing the acne protocol, not a year after.
FAQs
Why do my marks last months when my friend's fade in weeks? Skin tone (more melanin = more deposit per inflammation), lesion depth, picking history, and sun exposure — the four-variable lottery.
Will one TCA spot-peel erase a dark mark? Stubborn discrete marks respond to spot protocols — inside expert hands and the depth-discipline rules from the peels article.
Do dark spots mean my acne treatment failed? No — marks are the receipt of past inflammation; their fading tracks your control succeeding.
Makeup while treating? Freely — non-comedogenic formulations; concealer is morale, and morale is compliance.
