What Is Acne Scar Laser Treatment?
Acne scar laser treatment is a non-surgical procedure that uses focused light energy to improve the texture and appearance of skin damaged by past acne. Rather than removing scars entirely, lasers work by stimulating the skin’s natural repair mechanisms, encouraging the production of collagen — the structural protein that keeps skin smooth and firm.
There are two broad categories used in clinical practice: ablative lasers, which remove the outermost layer of skin, and non-ablative lasers, which deliver energy beneath the surface without breaking the skin. A common middle ground is the fractional approach, where the laser treats only a fraction of the skin in a grid-like pattern, leaving surrounding tissue intact and dramatically reducing recovery time.
CO2 Fractional Laser
The CO2 fractional laser is one of the most well-studied devices for atrophic (depressed) acne scars — the type that leaves pits or uneven texture in the skin. It creates microscopic columns of thermal energy deep into the dermis, triggering a wound-healing response that generates new collagen over several weeks. The CO2 fractional laser is available at the Kojimachi Dermatology & Plastic Surgery Clinic in Ichigaya — feel free to ask about it during a consultation.
Pico Laser
Pico lasers, such as PicoWay(FDA approved), deliver ultra-short pulses of energy measured in picoseconds (one trillionth of a second).
In addition to treating pigmentation and post-acne dark marks, pico technology in its RESOLVE fractional mode can stimulate collagen remodelling with minimal surface damage. This makes it a popular option for patients with darker skin tones or those who cannot afford significant downtime.
How Laser Treatment Works on Acne Scars
When laser energy is delivered to scarred skin, it creates a controlled injury at a precise depth. The body interprets this as damage and responds by producing new collagen and elastin fibres. Over time — typically four to twelve weeks after each session — the treated area gradually becomes smoother and more even in texture.
The mechanism differs slightly by scar type. Rolling scars (shallow, wave-like depressions) and boxcar scars (wider, defined edges) respond differently than ice-pick scars (deep, narrow channels). A clinician’s assessment of your specific scar morphology will determine which laser approach, energy settings, and number of sessions are most appropriate.
In our clinical experience at BIOTOPE CLINIC or Kojimachi Dermatology & Plastic Surgery Clinic, patients frequently present with a mixed pattern — a combination of rolling and boxcar scars alongside post-inflammatory hyperpigmentation. In these cases, a combination approach, such as pairing CO2 fractional laser with pico laser sessions, can address both texture and pigmentation simultaneously.
Expected Results: What the Evidence Shows
It is important to approach laser treatment for acne scars with realistic expectations. Significant improvement is achievable for most patients, but complete elimination of scarring is rarely possible with laser alone.
Studies suggest that CO2 fractional laser treatment can produce a 50–75% improvement in atrophic acne scars after a series of sessions, as measured by standardised clinical grading scales. A systematic review published in Dermatologic Surgery found that fractional ablative lasers consistently outperformed non-ablative options in depth of improvement, though with correspondingly more downtime.
Clinical reports indicate that pico laser fractional treatments achieve a 30–55% improvement in scar appearance with fewer side effects and shorter recovery, making them a practical option for those with busy schedules or pigmentation concerns. Results build progressively; most patients require three to five sessions spaced four to eight weeks apart before the full effect is apparent.
Dr. Karibe’s Note
Many of our international patients are surprised to learn that the depth and type of their acne scars matter far more than which laser device is used.
I always assess scar morphology carefully before recommending any protocol, because a treatment plan that works well for rolling scars may be quite different from what is needed for ice-pick scars. A thorough initial consultation is not just a formality — it is where the real planning begins.
Acne Scar Laser Treatment Cost in Tokyo
The cost of laser treatment for acne scars in Tokyo varies depending on the device used, the area treated, and the number of sessions required. At Kojimachi Dermatology & Plastic Surgery Clinic, the following price ranges apply:
| Treatment | Price Range (per session) | Typical Use Case |
|---|---|---|
| CO2 Fractional Laser | ¥11,000 – ¥66,000 | Atrophic (depressed) acne scars, enlarged pores, texture |
| Pico Laser (PicoWay) | ¥11,000 – ¥98,000 | Post-acne pigmentation, mild textural improvement |
| Laser Toning | ¥15,000 – ¥135,000 | Post-inflammatory hyperpigmentation, overall brightness |
| Dermapen (RF microneedling adjunct) | ¥9,800 – ¥220,000 | Collagen stimulation, can be combined with laser |
An initial consultation at the clinic is priced at ¥3,300. Because the total cost depends on your specific scar pattern and the number of sessions your clinician recommends, the per-session figures above should be treated as a guide rather than a fixed quote. For an accurate quote, we recommend booking a consultation.

What to Expect: Before, During, and After Treatment
Before Your Session
A consultation will include a thorough assessment of your skin type, scar morphology, and medical history. You may be advised to avoid sun exposure, retinoids, and certain skincare actives for one to two weeks prior to treatment. Patients with a history of cold sores may be prescribed antiviral medication as a precaution before ablative procedures.
During the Procedure
A topical numbing cream is applied to the treatment area approximately thirty to forty-five minutes before the session begins. The laser handpiece is passed over the skin in a systematic pattern. Patients typically describe the sensation as a warm prickling or snapping feeling. Most full-face CO2 fractional sessions take twenty to forty minutes; pico laser sessions are generally shorter.
After Treatment and Recovery
Following CO2 fractional laser, redness, swelling, and a sunburnt appearance are expected for three to seven days. The skin will feel rough and may peel as the treated channels heal. Strict sun avoidance and diligent use of a high-SPF sunscreen are essential during recovery. Pico laser sessions typically involve less downtime — mild redness that settles within one to two days in most cases.
Improvement continues gradually over the weeks following each session as new collagen is deposited. Final results from a course of treatment are usually fully visible three to six months after the last session.
Common Misconceptions About Acne Scar Laser Treatment
Misconception 1: One Session Is Enough
A single laser session is unlikely to produce dramatic or lasting improvement in acne scars. Collagen remodelling is a biological process that unfolds over months, and meaningful textural improvement typically requires multiple sessions. Patients who expect transformative results after one treatment may be disappointed; a realistic course of three to five sessions spread over several months is the standard clinical approach.
Misconception 2: Laser Treatment Works the Same on All Skin Tones
This is an important safety consideration. Individuals with darker skin tones (Fitzpatrick skin types IV–VI) face a higher risk of post-inflammatory hyperpigmentation (darkening of the skin) or hypopigmentation (lightening) with certain ablative lasers.
This does not mean laser treatment is unavailable, but it does mean that device selection, energy settings, and pre-treatment priming with appropriate skincare are especially important. A clinician experienced in treating diverse skin tones should assess candidacy carefully before proceeding.
Who Is a Good Candidate?
Laser treatment for acne scars is generally well-suited to adults whose active acne is controlled or in remission. Good candidates typically have atrophic (depressed) scars — such as rolling, boxcar, or ice-pick scars — rather than raised (hypertrophic or keloid) scars, which require a different treatment approach.
Patients who are pregnant or breastfeeding, those currently using isotretinoin (a prescription oral acne medication), and individuals with a history of keloid formation are generally advised to postpone laser procedures. Anyone planning significant sun exposure — including a beach holiday — immediately after treatment should time their sessions accordingly.
At our clinic in Ichigaya, Tokyo, we frequently see patients from varied ethnic backgrounds, and our clinical team takes skin type into careful consideration when recommending devices and settings for each individual.
Frequently Asked Questions
- Q. How many laser sessions will I need for acne scars?
- The number of sessions depends on the severity and type of scarring, as well as the device used. Most patients undergoing CO2 fractional laser require three to five sessions spaced four to eight weeks apart. Pico laser protocols are similar. Your clinician will provide a personalised recommendation after an in-person assessment.
- Q. Is acne scar laser treatment painful?
- A topical anaesthetic cream is applied before treatment to minimise discomfort. Most patients describe the sensation as a warm prickling or mild stinging. CO2 fractional laser tends to be more intense than pico laser, but the level of discomfort is generally manageable. Any significant pain during the procedure should be communicated to the clinician immediately.
- Q. Can laser treatment be combined with other acne scar procedures?
- Yes, combination approaches are common and often produce better overall outcomes. Laser treatment is frequently paired with treatments such as Dermapen (microneedling), RF microneedling, or filler injections for deeper scars. Your clinician will advise whether a combined protocol is appropriate for your specific scar pattern and goals.
- Q. Will my acne scars return after laser treatment?
- Laser treatment produces lasting improvements to existing scar tissue. However, if active acne continues to develop, new scars can form. For this reason, ensuring that active acne is well controlled before and during a course of laser treatment is an important part of a comprehensive management plan.
- Q. Are consultations available in English at your clinic?
- Yes. BIOTOPE CLINIC or Kojimachi Dermatology & Plastic Surgery Clinic offers consultations in English for international patients. The initial consultation fee is ¥3,300. Patients are welcome to raise any questions about their scar type, treatment options, and expected costs during this appointment.
