Melasma cannot be erased in one go; it is lightened step by step, with the possibility of recurrence in mind. The number of sessions and response vary by individual, and with tattoos the response may be limited depending on ink color and depth.

PicoWay / PicoWay Resolve
A picosecond laser that shatters pigment into fine particles
PicoWay is a pigment laser that uses ultra-short picosecond pulses — trillionths of a second — to shatter pigment into fine particles.

How we approach it
The same device can be run very differently.
This is not simple pico toning on a single parameter. We work in multi-layer focusing, with parameters adjusted individually to the type and depth of the pigment and the baseline condition of the skin.

02What to expect
Changes over time
Because it relies on a photoacoustic effect (a shockwave of light) rather than heat damage, it targets melasma, sun spots, and tattoo ink with less stress on the surrounding skin.
03Device & Technology
PicoWay Device

Picosecond pulses
Pulses measured in trillionths of a second break pigment into fine particles through a photoacoustic effect rather than heat — a way of reducing the load on surrounding skin.
Resolve handpiece
It creates micro-regenerative spaces within the skin (LIOB), which is also used for pores, scars and texture.
Certified genuine
Genuine Candela equipment, cleared by the US FDA and approved by Korea's MFDS.

06FAQ
Frequently asked questions
How does PicoWay reduce pigment?
PicoWay is a laser that breaks pigment particles into fine fragments using ultra-short pulses measured in picoseconds (1 trillionth of a second). Its key feature is that it uses a shockwave of light (photoacoustic effect) rather than burning with heat, reducing stress on the surrounding skin. The shattered pigment fades gradually over a course of sessions, so it does not disappear all at once.
Which skin concerns is PicoWay used for?
It is mainly used for pigmented lesions such as melasma, sun spots, and freckles, and for removing tattoos and eyebrow tattoos. With the Resolve handpiece, it is also used for pores, fine scars, and skin texture. A single face often has several types of pigment mixed together, so a board-certified dermatologist first identifies the type and depth of each lesion before treatment.
How many melasma toning sessions do I need?
Treatment typically involves 5-10 or more sessions at 2-4 week intervals, gradually lightening the tone. Melasma is not a lesion to erase in one go but one to lighten and manage over time, so we adjust the interval and energy based on your response at each session. The number of sessions needed varies by individual depending on the lesion and skin condition.
Can it remove tattoos or eyebrow tattoos?
Yes, picosecond lasers are used to remove tattoos and eyebrow tattoos. However, several sessions are needed depending on the color and depth of the ink, and some colors may show a limited response. We advise you on the number of sessions needed after examining the tattoo at consultation.
What is Resolve?
Resolve is a fractional handpiece attached to PicoWay. It creates micro-regenerative zones (LIOB) within the skin and is used to improve pores, fine scars, and skin texture. Whether to plan it alongside pigment treatment is decided after consultation based on your skin condition.
How long does it take, and does it hurt much?
The treatment itself takes about 10-30 minutes depending on the area and extent. Pain is low to moderate, closer to the snap of a rubber band. If you are sensitive to pain, topical numbing cream can be applied as needed before treatment.
Can I return to daily life right away? Will scabs form?
With toning, most people can return to daily life right after treatment. Spot lesions such as moles, or tattooed areas, may form scabs that remain for several days. Letting scabs fall off naturally rather than picking them is important for preventing pigmentation.
When do results appear?
PicoWay is a treatment where change appears as sessions accumulate. For a few days after treatment, lesions may temporarily look darker, which is part of the recovery process. After that, tone and lesions gradually fade over sessions at 2-4 week intervals, though the pace varies widely between individuals.
When is StarWalker used instead?
The choice depends on the depth and thickness of the lesion. PicoWay is mainly used to lighten widespread pigment over a course of sessions or to break up tattoo ink, while StarWalker is often used for deep, dense pigment such as nevus of Ota. When several types of pigment coexist, the two devices are sometimes combined, and the choice follows the consultation findings.
Are there side effects? Are there cases where treatment should be postponed?
Temporary redness may occur after treatment, and pigmentation may rarely appear. In particular, excessive energy on melasma can actually make it worse, so we adjust the intensity to your skin condition. Be sure to tell us at your visit if you have recently had strong sun exposure or tanning, are taking photosensitizing medication, are pregnant, or have a wound or infection in the treatment area.
How should I protect my skin from the sun after treatment?
Sun protection has a major effect on treatment results, so it must be done carefully every day. Apply sunscreen of SPF30 or higher daily, and reapply every 2 hours when outdoors. On the day of treatment, do not rub your skin; wash gently and moisturize well.
How much does PicoWay cost? How do I book?
The cost depends on the lesion type, extent, and number of sessions, so it is confirmed after consultation. General reference prices can be found on the price list on our website. Booking and consultations are available via Naver Booking, our KakaoTalk channel, or phone (+82-51-710-1891), and consultations are also available via LINE.

Aftercare
Pigment · redness lasers
Pigment often darkens before it fades and flakes off. Getting through this phase and protecting the skin from the sun decide the result.
Recovery course
- Day of treatmentStinging and redness are expected. Focus on soothing and moisturising.
- Days 2–7Spots or melasma may darken and fine crusts may form. Do not pick them — let them fall off naturally.
- Weeks 1–2Crusts fall off and the colour lightens. Sun exposure on these areas can bring the pigment back.
- Between sessionsToning is usually repeated every 2–4 weeks; spot removal is decided according to progress.
Precautions
- Sun exposure: throughout recovery; apply sunscreen daily
- Picking crusts
- Exfoliating or whitening products on your own: for 1 week
When to contact the clinic
- The area where a crust fell off stays white or dark and spreads
- Weeping or swelling appears
Next session · next visitPigment rarely clears in one session. The number of sessions and interval are decided at consultation.
