Mokdong Laser Toning for Melasma

How to Properly Treat Melasma and Freckles

Mokdong Laser Toning

Hello.

I am Kim Jin-hyeon, Chief Director of U&I Clinic Mokdong Branch.

"I got toning to remove melasma, but why isn’t it fading?"

"My freckles seem to be getting darker, and it’s really upsetting."

Once melasma and freckles take hold, they often do not go away easily, so many people worry about them for a long time.

Some of you may have tried laser toning and found the effect minimal, or even felt discouraged after hearing that your pigmentation is "refractory."

Today, I’ll explain the features of Fotona StarWalker Toning, which is specialized for pigmentation treatment, its four wavelength technologies, and how it can be applied to various skin concerns.

What is Fotona StarWalker Toning?

Fotona StarWalker Toning is a laser device that combines uniform beam quality and pico fractional functionality, and it is used for treating refractory pigmentation and nevi.

The biggest difference from conventional laser toning is its beam quality. By applying a new pulse method, it can deliver energy uniformly without irregularity.

This is thanks to a technology called EFC (Energy Feedback Control).

In general lasers tend to gradually lose energy as the treatment time gets longer,

but StarWalker Toning is designed to maintain consistent energy until the end of the procedure.

In addition, it has the advantage of combining the strong pulse power of pico seconds with pico fractional functionality.

As a result, there is less variation from one treatment area to another, and pigmentation improvement becomes more consistent overall.

That is why it is often used for conditions such as milk spots and refractory pigmentation that do not easily fade.

Four wavelengths and ASP Pulse technology

The key reason Fotona StarWalker Toning is regarded as strong for refractory pigmentation lies in its four-wavelength system.

-1064nm

-650nm

-585nm

-532nm

With these four wavelength ranges, it can selectively destroy pigmentation at various depths while minimizing damage to skin tissue.

This makes it possible to provide customized treatment for each type of pigmentation, from deep-set melasma to superficial freckles and spots.

In addition, it also applies a proprietary technology called "ASP Pulse."

Unlike conventional single-mode toning, it combines the strong pulse power of pico seconds with Q-switched laser technology,

and depending on the purpose of treatment, it can be freely switched between long-pulse mode, pico + nano Q-switched mode, and fractional mode.

There are also two handpieces.

The full-beam handpiece concentrates the laser on a single point so it can reach deep into the skin while minimizing thermal damage.

The fractional handpiece is used to induce collagen production and improve skin elasticity and tone.

As such, the ability to combine wavelengths, modes, and handpieces in multiple ways is what strengthens its role in refractory pigmentation treatment.

Customized applications by skin concern

Because Fotona StarWalker Toning is a device that can be broadly applied not only to pigmentation but also to a variety of skin concerns,

it can address melasma and overall skin tone improvement, as well as freckles, spots, and even refractory pigmentation or nevi.

It can also be applied to vascular conditions such as redness, and it is often used for surface texture refinement, including pores, scars, and skin texture improvement.

The left is before treatment, and the right is after treatment.

However, for any concern, the results can vary greatly depending on how "which wavelength" and "which mode" are combined, so customized planning based on an accurate diagnosis is more important than anything else.

In particular, it is good to keep in mind that long-standing pigmentation such as melasma or freckles does not disappear all at once, but improves gradually over multiple sessions.

After treatment, temporary redness or mild stinging may occur, but in most cases it recovers within a short time and does not significantly interfere with daily life.

So far, for those of you considering Mokdong laser toning, we have looked closely at the features of Fotona StarWalker Toning and how it is applied according to different skin concerns.

Please remember that the more stubborn the pigmentation, such as melasma and freckles, the more important it is to choose the right combination of wavelength and mode for your own pigmentation.

I hope you will continue to manage it consistently through customized treatment tailored to your pigmentation depth and skin condition after 충분한 consultation, and I will wrap up here.

This was Kim Jin-hyeon, Chief Director of U&I Clinic Mokdong Branch.

Thank you.
