Fractional laser
Very fine columns of laser heat, set close together in the skin, stimulate the dermis to rebuild its structure.
Depth: dermis This is a model, so layer thickness is not to scale.
How it works
Examination firstIf red, pus-filled acne is still present, we start with medication, covered by National Health Insurance (NHI), before any scar treatment.
01What it uses
Laser light split into fine points
The beam is divided into many tiny points and delivered densely to just a fraction of the skin.
02Which layer
Dermis
The light forms columns of heat that pass through the epidermis into the dermis. The skin between the columns is left untouched.
03How it works
Surrounding skin fills in and rebuilds
The untouched skin around each column fills it in, and new collagen forms along the way. Sessions are spaced 4 weeks apart to give the skin time to recover.
Concerns and how it works
If this sounds like you
- I have pitted acne scars
- The pores on my cheeks look large
- My skin feels bumpy and uneven
In acne scars and enlarged pores, collagen in the dermis has thinned or tangled unevenly. Instead of removing the entire surface, a fractional laser creates very fine columns of heat in a dotted pattern. As the surrounding skin fills those spots in, new collagen forms, and changes appear slowly over several months.

Common questions
What people often ask about fractional laser
How much pain should I expect?
Even with numbing cream, you will feel stinging and heat. We cool the skin throughout the treatment to ease the warmth.
How long will it take me to recover?
Expect redness for 3–5 days, swelling for 2–3 days, and tiny scabs. You can wear makeup starting the next day.
How many sessions will I need?
Usually 3–5 sessions, 4 weeks apart. The number depends on the depth and shape of the scars, and we follow your progress with you over several months.
Can I combine it with other treatments?
In the Danjeong Glow program, it can be planned as an optional add-on to the skin booster, done on a separate day. If acne is still active, we treat it with medication at the same time (covered by NHI).
