Q-Switched Laser in Seongsu, Seoul
The Miin Q-switched 1064nm laser for pigment, freckles, age spots and texture
A Q-switched laser uses extremely short pulses of light to break up pigment. At Seongsu Melting Clinic in Seongsu, Seoul, the Q-switched device is the Miin laser (1064nm), which is used for pigment work and, with a special handpiece, for pores and scars.
Here is how it works and what it can and cannot do.
What is a Q-switched laser?
"Q-switching" is a technique that stores laser energy and releases it in a burst lasting only billionths of a second. That burst is so fast that it shatters pigment particles before much heat spreads to surrounding tissue. The body's immune cells then gradually clear the fragments.
The 1064nm wavelength reaches relatively deep and is often chosen for Asian skin because it is less absorbed by surface pigment than shorter wavelengths, which may lower the risk of irritation when used carefully.
How we approach the Miin laser at Seongsu Melting Clinic
For pigment, Dr. Park Kyung-min uses the Miin laser in two ways. At low energy across the whole face, it becomes laser toning for diffuse pigment and dullness. At targeted settings, it can treat individual freckles, sun spots and age spots.
For texture, the Miin laser can be fitted with an MLA (micro lens array) handpiece. It focuses the energy into many tiny points inside the skin, which may help with pores and shallow scars with less surface damage than resurfacing lasers.
Before any spot is treated, it is examined. Not every brown mark is a freckle, and some lesions need a different device or a medical opinion first.
A good fit if…
- You have freckles, sun spots or age spots
- You have uneven pigment or dullness and want gradual improvement
- You want a lower-downtime option for pores and shallow scars (MLA)
- You can protect your skin from sun afterward
Consider something else if…
- You are pregnant
- You have a fresh tan or sunburn
- A spot is changing, bleeding or irregular (it should be assessed medically first)
- You have active melasma that tends to flare with stronger energy (toning is usually safer)
What to expect
After consultation, the area is cleansed and your eyes are protected. You will feel quick snaps like a rubber band. Targeted spot treatment may leave spots darker for a while, then they crust lightly and flake off over roughly a week or so. Toning and MLA treatments usually cause brief redness only.
Some spots clear in one session; others need more. Freckles may return with sun exposure. Pricing is explained at consultation.
Aftercare
- Keep treated spots clean and moisturized; do not pick crusts
- Use sunscreen daily and wear a hat outdoors
- Avoid strong exfoliants for several days
- Tell the clinic if a treated spot darkens more over time instead of fading
A note from Dr. Park
Dr. Park's approach is to diagnose before treating. He often explains that the same brown color can come from very different causes, and that a laser that clears a freckle may irritate melasma. That is why he examines each spot before choosing single, double or Miin mode, or deciding not to treat.
Frequently asked questions
Will pigment come back?
It can. Freckles and sun spots often return with sun exposure. Daily sunscreen helps keep results longer.
Can the Q-switched laser treat melasma?
At low-energy toning settings it is often part of a melasma plan. Strong spot settings are usually avoided on melasma.
What is the MLA handpiece for?
It splits the energy into many focused points to support pore and texture improvement, with less surface damage than resurfacing lasers.
