Why IPL Can Worsen Melasma
IPL can worsen melasma in some patients because its broad-spectrum heat can drive inflammation and rebound in this heat-sensitive condition. Gentler, melanin-sparing 1064 nm approaches are the preferred path for melasma care.
Does IPL make melasma worse?
It can in some patients. IPL delivers broad-spectrum light, much of which becomes heat, and melasma is a heat- and inflammation-sensitive condition — so aggressive IPL can trigger rebound pigmentation. It is not that IPL is ineffective; melasma is simply the wrong target for heat-heavy settings, which is why gentler, melanin-sparing 1064 nm approaches are the preferred path.
| Factor | IPL | 1064 nm picosecond |
|---|---|---|
| Light delivered | Broad-spectrum; much of the energy becomes heat | 1064 nm wavelength, less absorbed by epidermal melanin |
| Fit for melasma | Can trigger rebound in some patients | Preferred approach, with conservative settings |
Intense pulsed light (IPL) is effective for many pigment, sun-damage, and vascular concerns. But melasma is different, and IPL can worsen it in some patients. Melasma patients are common, motivated, and often already disappointed elsewhere — a clinic that understands why heat backfires, and owns the right tool, earns their trust and their loyalty.
The mechanism
IPL delivers broad-spectrum light, and a significant portion of that energy becomes heat. Melasma is a heat- and inflammation-sensitive condition: thermal injury can stimulate melanocytes and drive rebound pigmentation. So an approach that clears stable sun spots can backfire on melasma by adding exactly the trigger melasma reacts to.
Why melasma reacts differently
Unlike stable, superficial sun spots, melasma is chronic, relapsing, influenced by hormones and sun, and often carries a vascular component. Treatments that add heat or inflammation tend to provoke it. That’s why melasma protocols emphasize gentleness over aggression.
What to use instead
Melanin-sparing wavelengths are the safer path. The 1064 nm wavelength is less absorbed by epidermal melanin, which is why gentle 1064 nm protocols — such as the Pro 1 Pico’s picosecond 1064 nm — are used in melasma care, with conservative settings, test spots, and strict photoprotection. For the clinic, that turns melasma from a consult you decline into a course-based program you can offer with confidence.
IPL still has its place
This is a melasma-specific caution, not a verdict on IPL or narrowband DPL — both are workhorses for pigment, sun damage, redness, and vascular work. The DPL Elite narrowband platform, for example, runs pigmentation and redness protocols all day — while melasma calls for careful, conservative, evaluation-first treatment selection. Practices that run both platforms have the right answer for every pigment patient who walks in.

FAQs
Does IPL make melasma worse?
It can in some patients. IPL delivers broad-spectrum light, much of which is heat. Because melasma is heat- and inflammation-sensitive, aggressive IPL can trigger rebound pigmentation. It is not that IPL is ineffective — melasma is simply the wrong target for heat-heavy settings.
Why is melasma different from other pigment?
Sun spots and lentigines are relatively stable, superficial pigment. Melasma is chronic, relapsing, hormonally and thermally influenced, and often has a vascular component — so treatments that add heat or inflammation can worsen rather than improve it.
What is preferred instead for melasma?
Gentle, melanin-sparing protocols — particularly 1064 nm picosecond approaches that spare epidermal melanin — with conservative settings, test spots, and strict photoprotection, under provider direction.
Is IPL still useful?
Absolutely. IPL and narrowband DPL are workhorses for pigment, sun damage, redness, and vascular work. The caution is specific to melasma, where heat-heavy treatment carries rebound risk — which is why many clinics run a light platform and a picosecond laser side by side.
