How we approach it

The same device can be run very differently. This is how Grays approaches this treatment.

This is not simple 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.

Depending on the type, size and depth of the pigment and the baseline condition of the skin, we use PicoWay, StarWalker, GentleMax Pro, RedTouch Pro and Er:YAG lasers in combination.

02What to expect

Changes over time

It shatters pigment by switching wavelengths to match lesion depth, and its high-power single pulses can reach dense pigment and tattoo ink.

Every 4–8 weeks03

Stubborn pigment needs a plan spanning several sessions, and we explain the possibility of recurrence as part of it.

    Mild redness and stinging are possible. Do not rub — cleanse gently and moisturise well.

    Crusting and flaking

    If fine crusts form, do not pick them off. Letting them fall away naturally is what prevents pigmentation.

    Sun protection decides the result. Apply SPF 30 or higher daily, and reapply every two hours outdoors.

07FAQ

Frequently asked questions

What kind of laser is StarWalker MaQX?

StarWalker MaQX is a high-power pigment laser platform with multiple wavelengths and pulse modes. It switches wavelengths according to the depth of the lesion to break up pigment, and uses high-power single pulses to address dense pigment and tattoos. It is a device from Fotona of Slovenia, FDA cleared in the US and MFDS (Korean FDA) approved.

Which pigment concerns is StarWalker used for?

It is mainly used for difficult-to-treat pigmented lesions such as nevus of Ota and cafe-au-lait macules. It is also used for dense pigment that responded slowly to standard toning, or when tattoo removal is being considered. Even brown spots that look alike can differ in type and depth, so whether StarWalker is appropriate is first determined by a board-certified dermatologist's diagnosis.

How is it different from PicoWay?

The pulse method and power characteristics differ. Shallow, widespread pigment often favors PicoWay, while deep, dense lesions often favor StarWalker. Depending on the type and depth of pigment and your skin condition, it may be planned together with other lasers such as PicoWay or GentleMax Pro, so diagnosing the lesion comes first.

Can nevus of Ota be treated?

Yes, nevus of Ota, which has pigment in the dermis, can be treated with laser. However, it requires a long-term plan over multiple sessions, and response to treatment varies considerably between individuals. When we make the treatment plan, we also explain the possibility of recurrence.

Why are the treatment intervals long?

Deep lesions need time for shattered pigment to be cleared and for the skin to recover, so we typically space sessions 4-8 weeks apart. If intervals are too short, stimulation may be added again to skin that has not fully recovered. The timing of the next session is adjusted based on the response to the previous one.

About how many sessions will I need?

There is no fixed number; it depends on the type and depth of the lesion. Difficult-to-treat pigment often requires a long-term plan over many sessions. We advise you on the expected duration and number of sessions after assessing the lesion at consultation.

Does it hurt? How long does it take?

Many people feel moderate pain. Topical numbing cream is applied when needed, and the treatment takes about 10-30 minutes depending on the extent. How much pain you feel varies by area and individual.

How long do scabs and redness last after treatment?

Scabs and redness may form on the treated lesion and remain for several days. Scabs usually fall off within a few days to 1 week, and should be left to fall off naturally rather than picked. If you have an important event, we suggest choosing your treatment date with the scabbing period in mind.

Are there side effects or a chance of recurrence?

Temporary pigmentation or redness may occur after treatment. Difficult-to-treat pigment can recur even after treatment, and the degree of response varies widely by lesion and individual. Before treatment, we explain the expected response and limitations in detail.

Is there anything to be careful about before and after treatment?

Avoiding sun exposure and tanning before and after treatment is important. Be sure to tell us at your visit if you have recently had strong UV exposure, are taking photosensitizing medication, or are pregnant. After treatment, apply sunscreen of SPF30 or higher daily and reapply every 2 hours when outdoors.

How much does it cost?

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. Consultations can be booked via Naver Booking, our KakaoTalk channel, or phone (+82-51-710-1891), and are also available via LINE.

Fees

Pricing depends on lesion, extent, and number of sessions, and is confirmed after consultation.

Aftercare

Draft — pending medical director's review

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

  1. Day of treatmentStinging and redness are expected. Focus on soothing and moisturising.
  2. Days 2–7Spots or melasma may darken and fine crusts may form. Do not pick them — let them fall off naturally.
  3. Weeks 1–2Crusts fall off and the colour lightens. Sun exposure on these areas can bring the pigment back.
  4. Between sessionsToning is usually repeated every 2–4 weeks; spot removal is decided according to progress.

Avoid during this period

  • Sun exposure — throughout recovery; apply sunscreen daily
  • Picking crusts
  • Exfoliating or whitening products on your own — for 1 week

Contact the clinic if

  • 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.

Individual recovery varies. If it differs from what you expected, do not judge on your own — please contact the clinic. Tel +82-51-710-1891
