Pico Laser vs IPL for Melasma

For melasma, 1064 nm picosecond is often preferred over IPL: it spares epidermal melanin and acts photomechanically, not by bulk heat, while IPL's broad-spectrum heat can trigger rebound in some patients.

IPL and picosecond laser both address pigment, but melasma is heat-sensitive. This compares them for melasma specifically — why gentle 1064 nm picosecond is often preferred and why IPL's heat carries rebound risk in some patients.

  • Melasma is heat-sensitive; IPL's broad-spectrum heat can trigger rebound in some patients.
  • 1064 nm picosecond spares epidermal melanin and acts photomechanically rather than by bulk heat.
  • Neither is a cure — melasma is chronic and recurrence-prone.
  • Strict photoprotection and conservative settings matter regardless of device.

Key facts

Published studies report that 1064 nm picosecond laser can improve melasma, though results vary and may be comparable to established treatments; outcomes depend on individual factors and a course of treatment.

Same goal, very different physics

IPL and picosecond laser both address pigment, but melasma is a special case. Because melasma is heat-sensitive, the physics of how a device delivers energy matters more here than for stable sun spots.

IPL — broad-spectrum, heat-driven

IPL delivers broad-spectrum light, much of which becomes heat. For stable, superficial pigment that’s often fine — but for melasma, that thermal load can drive inflammation and rebound pigmentation in some patients. (See Why IPL Can Worsen Melasma.)

Picosecond 1064 nm — melanin-sparing, photomechanical

The Pro 1 Pico’s 1064 nm picosecond delivery is less absorbed by epidermal melanin and acts through a photomechanical effect rather than bulk heating — which is why gentle 1064 nm protocols are favoured for pigment-prone and darker skin in melasma care, where appropriate.

The evidence, honestly

Published studies report 1064 nm picosecond laser can improve melasma, but the evidence is modest and melasma recurs — see the cited key facts above. The right choice depends on the patient, skin type, pigment behaviour, and provider judgment; photoprotection is essential either way.

FAQs

Is pico laser or IPL better for melasma?

For melasma specifically, gentle 1064 nm picosecond approaches are often preferred where appropriate, because they spare epidermal melanin and act photomechanically rather than by bulk heat. IPL's broad-spectrum heat can trigger rebound in some patients. Neither cures melasma, and provider judgment governs choice.

Why does heat matter for melasma?

Melasma is heat- and inflammation-sensitive; thermal injury can stimulate more pigment and cause rebound. A photomechanical 1064 nm picosecond approach minimizes bulk heating, which is why it's favoured for this condition.

Does that mean IPL is bad?

No. IPL and narrowband DPL are valuable for many pigment, sun-damage, and vascular concerns. The caution is specific to melasma, where heat-heavy treatment carries rebound risk.

How long does melasma treatment take either way?

Melasma is treated as a course over time with maintenance, and outcomes depend on individual factors and sun protection. There is no one-time clearance with either approach.
