Acne Scar Treatment in Bangkok

Acne can leave four different kinds of marks behind: red marks, brown marks, pitted scars, and raised bumps. Each one needs a different treatment, and most people have more than one type.

We treat the full range:

• Red and brown marks: vascular and pigment-targeting lasers
• Pitted texture: resurfacing lasers, RF microneedling, subcision
• Volume loss: dermal fillers and biostimulators

Our dermatologists assess your scar mix and design a plan matched to your skin.

Types of Acne Scars

Around half of people with acne develop some form of scarring, and most have more than one type.

Identifying your mix is the first step toward matching the right treatment.

Red Marks (PIE)

Pink, red, or purple flat marks left after a breakout heals. Technically not scars, just discoloration from blood vessels still recovering from the inflammation. Common on lighter skin (Fitzpatrick I to III).

Red marks fade slowly on their own over many months. Vascular-targeting laser treatments speed the process by precisely targeting the underlying blood vessels: Dual Yellow Laser, Blink, or IPL, chosen based on your skin tone.

Brown Marks (PIH)

Tan to dark brown patches where acne was inflamed. Not technically a scar either; it’s pigment the skin produced during inflammation. Common on darker skin (Fitzpatrick III to VI).

PIH typically resolves on its own in 3 to 12 months, longer in darker skin or with continued sun exposure. Pigment-targeting lasers (IPL, Blink, and the green wavelength of Dual Yellow) can speed fading.

In darker skin (Fitzpatrick IV to VI), we usually recommend topical lightening agents first and use energy devices conservatively to reduce the risk of making pigmentation worse.

Pitted Scars (Atrophic)

Depressed scars where collagen was lost during healing. These are what most people picture when they think of acne scarring, and they don’t fade on their own. Three sub-types:

• Ice pick: narrow V-shaped pits up to 2 mm wide.
• Boxcar: oval or round depressions with sharp edges.
• Rolling: wide, shallow undulations from tethered fibers beneath the skin, up to 5 mm across.

Each sub-type calls for a different mix of treatments. We cover the full range below.

Raised Scars (Hypertrophic and Keloid)

Raised scars sit above the surrounding skin from too much collagen during healing. More common on the chest, back, and shoulders than the face, and in darker skin types when they do appear on the face.

These aren’t the focus of this page. If you have raised acne scars, mention them at consultation and we’ll route you to the right plan.

How We Treat Acne Scars

Most people have a mix of scar types: a few rolling scars, some boxcar texture, lingering brown marks. A single modality rarely addresses all of them efficiently.

We design plans that combine treatments matched to your specific pattern. Combination approaches often deliver better results than any single treatment alone.

Your plan is built around your mix of scar types, your skin type, your downtime tolerance, and your goals.

Common pairings we use:

• Subcision plus filler or biostimulator in the same session: release the tether, refill the volume
• CO2 laser plus RF microneedling at staggered intervals: surface remodel and deeper collagen induction
• Vascular laser (Dual Yellow, Blink, IPL) plus atrophic treatment: for mixed PIE/PIH and pitted texture
• In-clinic treatment plus at-home maintenance

Pricing at a Glance

Most plans combine modalities. We provide a detailed plan and full pricing at your free consultation.

Are the Results Permanent?

Most acne scar treatments work by stimulating your skin to build new collagen. Once that collagen forms, it becomes part of your skin’s structure, so results tend to be durable. Some scars, especially tethered ones, can benefit from occasional maintenance touch-ups.

Complete erasure isn’t something any current treatment can reliably promise. The realistic goal is meaningful, lasting improvement, not perfect skin.

Most people see roughly 50% reduction in scar appearance with a personalized plan, and some achieve more.

The picture is different for the four kinds of marks acne can leave behind:

• Red marks (PIE) and brown marks (PIH) fade naturally on their own, typically over 3 to 12 months. Treatment in clinic speeds the process significantly, but the marks would eventually go even without intervention.
• Pitted scars (atrophic) don’t fade on their own. They need professional treatment to see meaningful improvement. Once we rebuild collagen in the depressed area, that new collagen is part of your skin.
• Raised scars (hypertrophic and keloid) are flattened with injections; results vary by scar type and may need touch-ups over time.

Treating sooner produces better results than treating older established scars. If you’ve recently finished your acne recovery, this is a good time to start.

How Many Sessions are Needed?

You’ll see visible improvement after the first session. Full results typically build over a series of 3 to 6 sessions, spaced 4 to 6 weeks apart, with each session running 15–60 minutes.

Visible improvement starts around 6 to 8 weeks after a session. Full collagen remodeling continues for several months and often improves for up to a year.

The plan is iterative: we treat, allow time for the skin to remodel, assess the response, then decide whether to continue or adjust.

Newer scars respond faster than older established scars, so the overall timeline tends to shorten when treatment starts soon after acne clears.

If You’re Visiting Bangkok

If you’re in town for a short trip, we can design a single-visit plan tailored to the time you have.

Subcision plus dermal fillers or biostimulators (Sculptra, Radiesse) delivers immediate scar release and volume restoration in one session. Non-ablative lasers (Dual Yellow, Blink, IPL) and RF microneedling have minimal downtime and pair well in a single visit.

CO2 ablative laser needs 5 to 7 days of recovery, so factor that into your trip if it’s part of your plan.

Many visiting clients follow up with additional sessions during a return trip, or coordinate ongoing care with their home dermatologist.

Am I a Good Candidate?

Five inputs go into your treatment plan:

• Scar type: atrophic (ice pick, boxcar, rolling) versus raised (hypertrophic, keloid); plus any PIE/PIH overlay
• Skin type and tone: darker skin (Fitzpatrick IV to VI) is more sensitive to ablative laser and may be routed to RF microneedling first
• Severity: mild scars may respond to a lighter modality mix; deeper scars often need CO2 plus subcision plus volume restoration
• Downtime tolerance: CO2 needs 5 to 7 days off; non-ablative options keep you working
• Active acne status: must be controlled before scar treatment

When to wait

• Active acne not controlled: treat acne first. Scar treatments cause deep skin inflammation that can flare active acne directly, so treating scars while breakouts are uncontrolled often makes things worse. Start with our acne treatment options first.
• Recent sun exposure or sunburn: wait until your skin has fully recovered.
• History of keloid scarring or active skin infection: consultation will assess your suitability case by case.

Pre-treatment for Darker Skin Tones

For Fitzpatrick III and above, a short pre-treatment phase using prescription topicals for about 4 to 8 weeks before laser or RF microneedling can reduce the risk of post-treatment hyperpigmentation. Your doctor will assess your skin tone and tailor the regimen and duration at consultation.

Side Effects & Risks

Acne scar treatments are generally safe, with most side effects mild and temporary.

Common (resolve within days):

• Redness, swelling, mild tenderness
• Bruising (more common with subcision and any deeper injectable)
• Itching during healing
• Peeling or crusting (5 to 7 days for CO2 specifically)

Less common:

• Pigment changes, especially in darker skin tones (minimized by skin-type-matched settings and pre-treatment when needed)
• Infection (rare with proper aftercare)
• Hypertrophic scarring (very rare)

We minimize risks through thorough pre-treatment screening, individualized settings based on your skin type and scar pattern, and clear aftercare guidance after every session.

Aftercare

Aftercare varies by treatment, but the baseline is the same across all of them:

• SPF 50 or higher daily; avoid direct sun for 2 to 4 weeks after laser
• No exfoliants for 1 to 2 weeks
• Gentle, non-foaming cleanser
• Hydrating moisturizer

Treatment-specific notes:

• CO2 laser: 5 to 7 days of careful management. No makeup for 1 to 2 weeks. Gentle cleansing only. Full instructions provided at the appointment.
• Non-ablative lasers (Dual Yellow, Blink, IPL): little to no downtime; resume normal skincare within 24 hours.
• Subcision: ice the area initially. Expect bruising for 1 to 2 weeks. Oral antibiotics may be prescribed.
• RF microneedling: mild redness for 24 to 72 hours. After treatment, we apply only sterile, intradermal-grade products (like our skin boosters); these can safely penetrate deeper through the micro-channels. Everyday cosmetic serums aren’t formulated for intradermal delivery and have been linked to skin reactions in case reports.
