Post-Acne & Wound Pigmentation: Why Laser Toning and Brightening Care Must Go Hand in Hand

Does Pigmentation

Disappear Right Away

After Laser Treatment?

Hello,

This is Dr. Wi Young-jin from Beautystone Clinic.

Q. Can't pigmentation be completely cleared

with just a few laser sessions?

A. Laser alone is not enough.

Melanin pigment needs to be slowly

'eliminated' out of the skin,

and brightening care plays a crucial role in supporting that process.

Q. Why does pigmentation take so long to fade?

A. After inflammation or injury, the skin overreacts

and produces excess melanin,

which can migrate deep into the Dermis and settle there.

📌 Key Takeaway

Post-inflammatory pigmentation left behind by wounds or acne

requires a combined approach of Laser toning

and brightening ingredient care

to gradually and effectively eliminate melanin pigment.

Why Doesn't Pigmentation

Just Fade on Its Own

Over Time?

This is a common misconception,

so let's start by understanding

how pigmentation actually forms.

When Acne, wounds, or inflammation occur,

the body works to repair the damaged area

while simultaneously stimulating melanocytes

to create a 'protective barrier.'

When this response is excessive,

pigmentation forms at the site.

Here's where it gets nuanced —

pigment that remains in the superficial layers of the Epidermis

can naturally rise to the surface and shed over time.

However, pigment that has traveled deep into the Dermis

is an entirely different story.

Natural elimination is almost impossible at that depth.

Here's an important point to understand:

melanin doesn't simply disappear when it's 'destroyed.'

Laser breaks down pigment particles into smaller fragments,

but eliminating those fragments out of the skin

ultimately depends on the skin's own metabolic capacity.

That's why walking out of a laser session without any follow-up care

is only completing half the treatment.

To put it plainly —

Laser toning handles the job of fragmenting pigment particles.

But the next step — actually flushing those fragmented particles

out of the skin — slows down significantly

without proper brightening ingredient care.

Ingredients like Niacinamide, Vitamin C,

and Alpha-Arbutin work to suppress melanin synthesis

and support its elimination from the skin.

A simple analogy:

Laser toning is the machine that 'shreds the waste,'

while brightening care is

the 'garbage truck that hauls it away.'

You need both for the cleanup to be complete.

👨‍⚕️ Dr. Wi Young-jin's Key Summary

Post-inflammatory pigmentation left behind by wounds or acne

requires Laser toning to fragment melanin particles,

followed by brightening ingredient care

to actively facilitate their elimination from the skin.

Only when both steps are combined

does the pigmentation fade — 'slowly, but surely.'

So What Approach

Is Right for You?

It varies case by case,

but here's how I generally categorize it.

① Epidermal Pigmentation (Recent, Superficial)

If the mark is from Acne scarring or minor abrasions,

is less than 6 months old, and appears brownish in tone,

4–6 sessions of Laser toning combined with

a consistent brightening serum routine at home

is often more than enough to see significant fading.

② Dermal Pigmentation (Long-standing or Deep)

If the mark is over a year old or has a grayish hue,

it has likely penetrated into the Dermis,

and Laser toning alone will require considerably more sessions.

In these cases, combining treatments that target the Dermis —

such as iontophoresis or Pico laser —

delivers more efficient and effective results.

That said, an important point to keep in mind:

simply increasing laser intensity does not

accelerate the fading process.

In fact, excessive stimulation can reactivate melanocytes,

paradoxically causing pigmentation to become even darker.

This is exactly why 'low intensity, multiple sessions'

is our fundamental principle.

Some patients who saw no results after 10 sessions elsewhere

have been satisfied after just 2–3 sessions with us —

and looking back, nearly all of those cases

involved no brightening care being combined with treatment.

They were simply receiving laser and going home

without any follow-up management.

One thing I must be clear about:

pigmentation treatment takes time.

Even in fast-responding cases, expect at least 3 months.

For deeper pigmentation, plan for 6 months or more.

Starting without this awareness

often leads to giving up midway through.

However, patients who commit to consistent combined care

have largely achieved satisfying results.

Frequently Asked Questions

Q1. Do I really need to apply Sunscreen

throughout pigmentation treatment?

A. Absolutely — it's non-negotiable.

UV rays are the most powerful external trigger

for stimulating melanocytes.

No matter how well the treatment goes,

neglecting sun protection

will cause the pigmentation to return and deepen.

Apply an SPF50+ PA+++ or higher product

30 minutes before going outdoors,

and reapply every 2–3 hours — this is the baseline.

In fact, this single habit

accounts for more than half of your treatment outcome.

Q2. Are the treatments for pigmentation and melasma different?

A. Yes, they are.

Pigmentation is caused by external triggers (wounds, inflammation),

while melasma results from a complex combination

of hormonal, UV, and genetic factors.

With melasma, increasing laser intensity

can actually worsen the condition,

requiring a far more delicate and conservative approach.

Accurately determining whether your mark is

post-inflammatory pigmentation or melasma

is the single most important first step

in establishing the right treatment plan.

Q3. Can I resume daily activities immediately

after a Laser toning session?

A. Yes, you can.

Laser toning is a procedure with virtually no Downtime.

There may be mild redness or Heat sensation immediately after,

but this typically subsides within a few hours.

Face cleansing and makeup are generally possible on the same day.

However, it's best to avoid saunas

and intense exercise right after the procedure.
