Hyperpigmentation
Dark marks left behind by inflammation — treatable, but a marathon, not a sprint.
Hyperpigmentation is excess melanin that leaves flat, darker patches on the skin. The most common form, post-inflammatory hyperpigmentation (PIH), appears after the skin is inflamed or injured — by acne, a rash, a procedure, or trauma — and is especially common and persistent in richer skin tones.
The good news is that PIH is treatable. The honest news is that it’s slow: pigment sits at different depths, and fading it safely takes consistency and patience. Sun exposure is the single biggest obstacle, which is why photoprotection isn’t optional — it’s the foundation of every plan.
(Melasma, a related but distinct and more stubborn condition, has its own page, because it behaves differently and can be worsened by the wrong approach.)
The Non-Negotiable
Sun exposure is the single biggest obstacle to fading pigment.
At A Glance
What Drives It — and What Helps
Pigment responds best to a layered plan built on sun protection. Aggressive heat or light can backfire, especially in deeper skin tones.
Hyperpigmentation, simplified
Sun protection is the cornerstone — everything else builds on it
Common triggers
- Acne and inflammation
- Procedures or injury to the skin
- Rashes and irritation
- Sun exposure (worsens and prolongs it)
- Picking or aggressive treatment
What helps
- Diligent broad-spectrum sun protection
- Topical pigment-regulating agents (under care)
- Retinoids to speed cell turnover
- Carefully chosen chemical peels
- Selected lasers — cautiously in richer tones
Educational summary only; treatment is individualized to your skin tone and the depth of pigment. Over-aggressive treatment can worsen pigmentation.
The DetailsUnderstanding the Marks
Not all dark marks behave the same way:
Post-Inflammatory (PIH)
Flat brown marks after inflammation or injury; common after acne and in richer skin tones.
Sun-Induced
Pigment driven or deepened by UV and visible light — which is why protection comes first.
Depth Matters
Superficial pigment fades faster; deeper pigment is slower and needs a gentler, patient approach.
Skin Tone Matters
Richer skin tones are more prone to PIH and to pigment changes from aggressive treatment.
Not Melasma
Melasma is a distinct, hormone-influenced condition treated more cautiously — see its own page.
Time & Consistency
Even with the right plan, meaningful fading takes weeks to months of consistent care.
The OptionsHow Hyperpigmentation Is Treated
Treatment is layered and sequenced, always on a foundation of sun protection. Pushing too hard — especially with heat or light in deeper skin tones — can paradoxically worsen pigment, so restraint is part of the strategy.
Skincare first
A medical skincare plan — pigment-regulating actives, retinoids and daily broad-spectrum sunscreen — is the backbone and often the whole answer for superficial pigment.
Peels and devices
Carefully chosen chemical peels can accelerate fading. Lasers and light devices can help in selected cases but must be used cautiously in richer tones — see who shouldn’t get laser.
Treat the source
Because PIH follows inflammation, controlling the underlying cause — acne, irritation — is essential, or new marks will keep appearing.

Push too hard, and pigment can get worse before it gets better. Restraint is the strategy.
How We DecideEvidence-Based Practice
Aesthetic medicine changes rapidly, and novelty alone is not evidence. At Onassis Skin Health, treatment and skincare protocols are developed with reference to peer-reviewed medical literature and respected clinical guidance — then interpreted for the individual in front of us.
Research does not replace clinical judgment. It informs it.
Published evidence is read in the context of your anatomy, skin type, medical history, risk profile, lifestyle and desired outcome. Product and technique selection, dosing or placement, and pre- and post-care all follow from that combination of evidence and individualized assessment — not from what is simply popular or available for purchase.
When AppropriateA Layered Plan
Hyperpigmentation responds to a patient, layered plan rather than a single aggressive treatment:
+ Medical Skincare
A prescriptive regimen — including ZO Skin Health when appropriate — to treat the concern directly and support any in-office treatment.
+ In-Office Treatment
Laser or other procedures when they genuinely add value, matched to your skin and goals.
+ Photoprotection
Daily broad-spectrum sunscreen to protect results and prevent the concern from worsening.
Combinations are recommended only when each element contributes meaningfully to your goals. Sometimes the right plan is a single, well-chosen treatment — and sometimes it is choosing not to treat at all.
What to ExpectPatience Pays
Treatment is tailored to your skin tone and the depth of pigment, and it rewards consistency. For richer skin tones especially, a gentler, skincare-led approach is often safest. We’ll set realistic timelines — usually weeks to months — and prioritize not making things worse.
QuestionsFrequently Asked
Why is my hyperpigmentation so slow to fade?
Pigment sits at different depths and is continually re-triggered by sun exposure; safe fading takes consistency over weeks to months.
Is it the same as melasma?
No — melasma is a distinct, hormone-influenced condition that’s more stubborn and more easily worsened; it has its own page.
Can laser treat it?
Sometimes, but cautiously — especially in richer skin tones, where aggressive treatment can worsen pigment.
What’s the most important step?
Daily broad-spectrum sun protection — without it, nothing else works well.
Do I need to treat my acne too?
Yes — since PIH follows inflammation, controlling active acne prevents new marks.
