Mosaic in Busan Seomyeon

What is Mosaic, and what does it do?

Mosaic (Lutronic) is a non-ablative fractional laser at 1550 nm, the erbium-glass wavelength that water in the dermis absorbs moderately, so each micro-beam coagulates a narrow column of tissue below the surface without removing the skin above it. The columns heal from the intact skin between them within days while the heat they left triggers collagen remodelling over weeks: the principle the original Fraxel introduced, and the tier between picosecond fractional and the ablative lasers. It treats the aftermath of acne rather than acne itself: red marks, early rolling scars, uneven texture and enlarged pores, with two to three days of pinkness.

In Seomyeon, Mosaic is the laser the doctor adds once acne is controlled and the face is left marked and textured but not deeply pitted; at ₩275,000 a session or ₩1,100,000 for five it is a course, four weeks apart. Deeper scars go to Potenza, Scorpio or UltraClear on the scar plan; brown marks alone go to toning; the lighter fractional pass is PicoHi Fraxel.

Downtime after Mosaic, and flying home

Honestly stated: pink and slightly swollen on day one, a faint bronze tone and fine roughness on days two and three, make-up from day two. Fly after 24 hours. Texture smooths from week two and keeps improving for months.

Is Mosaic the same as Fraxel?

Same principle and the same 1550 nm wavelength as the original Fraxel re:store: non-ablative fractional columns that remodel the dermis under an intact surface. Mosaic is Lutronic's platform; patients who have had Fraxel elsewhere will recognise the session and the downtime. At Boom Dermatology it is the mid tier of the texture plan.

What does non-ablative mean for my downtime?

That no skin is removed: the columns are coagulated, not vaporised, so there is no open wound, no crust and no peeling, only two to three days of pinkness and a faint roughness under make-up. The trade is a course of sessions rather than one big one.

Can it treat acne scars, or only marks and texture?

Early and shallow rolling scars, yes, over a course; deep pitted or tethered scars, no, and we say so. Those go to Potenza, Scorpio or UltraClear, and our Seomyeon skin clinic reads which scars you have by stretching the skin at the consultation.

Is 1550 nm safe on Asian skin?

With conservative density and energy, yes; it heats below the pigment layer and is used widely on Korean skin. Post-inflammatory darkening is the risk designed around, so settings start low and rise with tolerance, and melasma-prone skin is treated cautiously or on a different tier.

How many sessions until texture changes?

Smoother from the second week after the first; marks and texture reading different in fixed-light photos from the third session; the full course three to five, four weeks apart, with the collagen still building months after the last. Each session is bought one at a time at Boom Dermatology in Busan, or as the five-session course.
