Pro 1 Pico for Melasma: 1064 nm First

The melasma case for Pro 1 Pico starts with 1064 nm. Its primary wavelength has lower relative epidermal melanin absorption than 755 nm, while the platform adds picosecond, PTP dual-pulse, and long-pulse 1064 nm treatment behaviors from one system.

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.

The melasma case for Pro 1 Pico starts with 1064 nm

There is a major difference between choosing a laser because it says picosecond on the brochure and choosing a platform because the wavelength architecture makes sense for the patient population you treat.

For melasma, Pro 1 Pico starts in the right place: 1064 nm.

That matters because melasma commonly presents in pigment-prone skin, where baseline epidermal melanin competes for incoming laser energy. Compared with 755 nm, 1064 nm has lower relative absorption by epidermal melanin and penetrates more deeply.

So the Pro 1 Pico melasma story is not:

“Picosecond is automatically better.”

It is:

1064 nm first. Because wavelength matters.

The evidence supports looking beyond the word “picosecond”

A 2023 systematic review and meta-analysis of six randomized controlled melasma trials evaluated picosecond systems across multiple wavelengths. In subgroup analysis, 1064 nm picosecond treatment significantly reduced MASI/mMASI, with no significant side effects reported in that subgroup. The 755 nm subgroup did not significantly outperform topical depigmenting agents and reported post-inflammatory hyperpigmentation.[1]

A separate randomized, assessor-blinded trial compared 1064 nm picosecond Nd:YAG, 755 nm picosecond alexandrite, and 2% hydroquinone in Fitzpatrick III–IV patients. The 1064 nm group achieved the greatest MASI reduction, while the 755 nm group performed similarly to hydroquinone.[2]

Those studies do not say that every 1064 nm device will outperform every 755 nm device. They make a more important point for an educated buyer:

Pulse duration does not erase wavelength physics.

One wavelength. Multiple treatment behaviors.

This is where Pro 1 Pico becomes more interesting than a single-mode pigment platform.

The provider can work from the same 1064 nm foundation through different energy-delivery behaviors:

500 ps 1064 nm picosecond
A photoacoustic pathway for pigment-focused treatment planning.

PTP dual-pulse delivery
A separate picosecond energy-delivery option that divides the pulse into paired sub-pulses.

Long-pulse 1064 nm Nd:YAG
A true photothermal pathway for appropriate vascular and thermal targets.

Those are different tissue interactions. They should not be blurred together — and that is exactly why having them on one platform matters.

Melasma itself is more complex than visible pigment

Histologic research has documented increased number and size of dermal blood vessels and increased VEGF expression in melasma lesions. That does not mean every melasma case requires vascular laser treatment, but it reinforces the idea that melasma biology extends beyond superficial pigment alone. View the PubMed record.

A 2025 randomized evaluator-blinded trial adds another useful piece of evidence. In Fitzpatrick III–IV patients, a combined Q-switched plus long-pulse 1064 nm Nd:YAG protocol produced significantly greater overall MASI improvement than a 755 nm picosecond alexandrite protocol.[3]

That study does not prove a universal pigment-plus-vascular protocol, and it did not enroll Fitzpatrick V–VI. What it does show is that a multi-mode 1064 nm treatment strategy deserves attention — and that evaluating melasma technology by pulse duration alone is too simplistic.

Why melasma rebounds — and why one platform carries both a picosecond and a long-pulse 1064 nm pathway.

Built for the patients around the melasma patient

The business case gets stronger when the conversation moves beyond one indication.

A patient who comes in asking about melasma may also be concerned about sun damage, uneven pigment, redness, visible vessels, pores, post-acne texture, scars, or overall skin quality.

Pro 1 Pico gives the practice multiple treatment categories from the same platform:

  • Melasma-focused and laser-toning protocols
  • Pigmentation and sun damage
  • Tattoo removal
  • PMU and microblading correction
  • Vascular redness, telangiectasia, and selected spider veins
  • PulseStack™ 750 skin-quality treatments
  • PicoMatrix™ Advanced Rejuvenation
  • PicoMatrix™ Scar Remodeling
  • PicoMatrix™ Texture & Pores
  • PicoMatrix™ Hair Restoration
  • Selected hair reduction
  • Carbon laser peel

Melasma may bring the patient in. Pro 1 Pico gives the practice far more to treat once they are there.

A melasma platform should make sense between melasma appointments

A capital device has to earn its treatment-room footprint across the week — not only when a melasma patient is scheduled.

That is the commercial advantage of a multi-mode platform. The same system can support corrective categories that attract new patients and repeat treatment categories that keep the platform in regular use.

Instead of asking only:

“Can this laser treat melasma?”

Ask:

“What else can I build around it?”

For Pro 1 Pico, that answer extends well beyond pigment.

Treat melasma intelligently. Build the practice broadly.

Melasma is recurrence-prone and should not be sold as a permanent-clearance procedure. That does not make it a weak treatment category. It makes good patient education, wavelength selection, provider judgment, and maintenance planning part of the service.

Pro 1 Pico pairs that treatment philosophy with a broader business advantage:

a 1064 nm-first platform with multiple treatment behaviors and multiple revenue categories from one system.

FAQs

Why does Pro 1 Pico use 1064 nm for melasma-focused treatment planning?

1064 nm has lower relative absorption by epidermal melanin than 755 nm and penetrates more deeply. That makes it a logical wavelength foundation when epidermal melanin sparing is important.

Is picosecond pulse duration alone what makes a laser suitable for melasma?

No. Pulse duration matters, but wavelength matters too. Published randomized melasma data show different outcomes between 1064 nm and 755 nm picosecond approaches, so the word 'picosecond' should not be treated as the whole technology story.

What does Pro 1 Pico add beyond 1064 nm picosecond delivery?

The platform adds PTP dual-pulse control and a separate long-pulse 1064 nm mode, while also supporting pigment, tattoo, PMU, vascular, skin-quality, scar, texture, and hair-restoration treatment categories from the same system.

Can Pro 1 Pico be used in treatment planning for darker skin types?

Its 1064 nm foundation is especially relevant when epidermal melanin sparing is a priority. Direct randomized melasma data in Fitzpatrick V–VI remain limited, so treatment selection and parameters still depend on provider judgment and patient assessment.

Does Pro 1 Pico cure melasma?

No laser should be positioned as a permanent cure for melasma. Melasma is recurrence-prone, so the goal is improvement, maintenance, and a treatment strategy appropriate to the individual patient.
