Key to know Gangnam acne scar laser treatment

Hello,
This is Dr. Park Kibum, Head Director of GU Clinic.

Even after acne has cleared,
the marks and scars left behind
can make the skin appear uneven.

While acne marks may gradually fade over time,
acne scars are a different story.

Today, we’ll discuss the causes of
Gangnam acne scars
and ways to improve them.

"Depressed scars

that makeup can’t fully cover"

Unlike post-acne pigmentation,
depressed acne scars are difficult to conceal with makeup
and often become more noticeable under light.

This is not simply a pigmentation issue—
it involves structural skin damage,
making improvement difficult through basic skincare alone.

To prevent deeper dermal damage
and structural deformation,
it is important to choose treatments
that stimulate skin regeneration.

"Gangnam acne scars come in different types"

Many people think of acne scars
as one single form,

but in reality, there are several types.

​

• Rolling scars: Wide and gently depressed

• Boxcar scars: Clearly defined with deep edges

• Ice pick scars: Narrow and deeply punctured

Because each scar differs in depth and shape,
it is important to create a customized treatment plan
rather than applying the same method to all scars.

Especially for deeper scars,
surface-level stimulation alone has limitations,
which is why deeper layers must also be considered.

"More precision

for more refined scar treatment"

UltraPulse Alpha for Gangnam acne scars
is a second-generation fractional CO2 laser
upgraded from previous Encore technology.

Rather than simply resurfacing the skin,
it delivers strong peak power in extremely short pulses,
penetrating up to 4mm into the dermis.

It is highly effective for
deep acne scars and enlarged pores.

The device also allows treatment density
to be adjusted in 1% increments,
enabling precise control by area.

This means treatment can be customized
according to scar depth and skin condition.

"Reducing thermal

burden during treatment"

Another advantage of UltraPulse Alpha is:

​

• CoolScan mode: Delivers laser energy in randomized patterns

• Brush mode: Randomized laser delivery without overlapping spots, ideal for larger areas

​

These modes help

reduce unnecessary heat damage to surrounding tissues
while minimizing discomfort during treatment.

As a result,
depth and mode settings can be adjusted
based on each individual’s skin and scar condition.

Today, we explored
UltraPulse Alpha laser treatment
for improving Gangnam acne scars.

Because acne scars involve structural skin changes,
the treatment approach is extremely important.

If you are considering acne scar treatment,
we recommend creating a personalized plan
based on your current scar condition.
