Laser Treatment for Acne Scars

I am looking for a way to get rid of acne scars. Heard good things about some laser skin treatments but i don't know how to choose between them all because there are so many laser treatments that are said to work on lots of problems, but i really just want to know which one works the best on acne scars.

Choice is less complicated with an experienced provider

The reason there are so many options for acne scar correction, is because there are different types of acne scars and there are relative strengths and weaknesses to all modalities to correct or improve acne scars. It is therefore very important to seek the advice of a board certified dermatologist with experience in all modalities in order to pick the one best for you.

  • Mild scars? Perhaps just SilkPeel or a series of peels is necessary.
  • Can't afford downtime? Cooltouch might be perfect.
  • Deeper scars? Fraxel Re:Store has been a true breakthrough, but does have 1-3 days of swelling that you must be prepared to experience.
  • Active acne? Isolaz may be for you.
  • Finally, severe scars may benefit from true resurfacing either with traditional dermabrasion, or a fractional CO2 laser device like Juvia or Fraxel Re:Pair. These procedures have at least one week of social downtime, but give the most dramatic result.

Please get the advice from someone familiar with the options and prepared to provide the one best for you.

Laser or Dermabrasion?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}


If the question was what is the best laser for treatment of acne scarring? The answer would unequivocably be the CO2 laser. The reason for this is that the best results are typically obtained with the depth of injury and the extent of and depth of the thermal injury of the treatment.

CO2 laser creates a great degree of collateral thermal damage and consequently produces the most dramatic results when it comes to correcting acne scarring and/or effacement of lines and wrinkles. The problems with CO2 laser treatment are extended downtime, prolonged erythema (redness), and eventual loss of pigmentation that invariably occurs with this modality.

This leads to the next topic, a more old fashioned, but tried and true treatment for acne scarring and scar revision.


Dermbrasion (as opposed to microdermabrasion) is an older modality which uses a rotating diamond tipped fraise (wheel) to remove the epidermis and portion of the dermis. The extent of the injury to be corrected is determined by the depth of injury created, which is gauged by the Surgeon's eye and experience. A depth of injury comparable to CO2 laser treatment is feasible with Dermabrasion. However, several factors make Physicians less comfortable with Dermabrasion than they perhaps should be:

  1. It is a very technically dependent treatment,
  2. Wide availability of a variety of lasers which produce a fairly uniform depth of injury based on the individual laser and the laser settings.

The aesthetic problem with acne scarring is caused by topographical irregularities, catching shadow and light. The benefit of Dermabrasion is that scars can be selectively planed down to be less noticable. The benefit Dermabrasion carries over CO2 laser is less thermal injury, far less chance of hypopigmentation (loss of pigmentation), and a much smaller window of erythema (redness of the face).

Due to its benefits, I incorporate Dermabrasion regularly into my practice for purposes of acne scarring and scar revision.

CO2 laser is the best for acne scars

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

I believe that the CO2 laser will give the best results for scars of the face. The best of these is the Fraxel re:pair Laser. This uses fractional technology, which has eliminated the risks of further scarring or hypopigmentation.

Nothing is going to remove all the scars, but with one or two treatments with the Fraxel re:pair, it should be significantly better.

Many treatments for acne scars

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

There are many different treatments for acne scars and there is not one that works for every patient. The first step is to ensure that any active acne is under control. The next step is to determine the best course or courses of treatment. This may include lasers, dermabrasion, dermaroller, excision, fillers, or other options. Finding a facial plastic surgeon, dermatologic surgeon, or plastic surgeon who offers a variety of treatments is going to be your key. Don't be swayed by advertising pictures which promise miraculous results as most single treatments will get about a 50% improvement (there are some exceptions).

Best laser for acne scars

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
The best laser to treat acne scars depends on the depth of the scar, your skin tone, the amount of downtime you can afford, your tolerance for discomfort during a procedure, and your budget. Ablative treatments like CO2 laser and dermabrasion give the most dramatic result, but there can be risks of pigmentation problems and a week of downtime. Fractionated lasers or IPL treatments have minimal downtime, but they may not give very dramatic results.
The only way to know for sure what the best treatment for you will be is to see a physician in person who treats acne scars routinely. I highly recommend getting more than one opinion so you can compare the approaches. If two or three plastic surgeons or dermatologists tell you the same thing, then you can be more confident that it's the best treatment for you.

Is possible to "erase" Acne spots and scars?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

There are a few types of post acne “spots” or “scars”.

One type: pink spots these are cause by dilated small capillaries and will fade by themselves after your active acne is controlled.

Second type: Brown flat spots. If you have these, you need to avoid the sun as much as you can and use a sunscreen morning and noon. Vitamin C serums and Niacinamide products applied at night can also help fading these brown spots.

Third type: depressed acne scars (pits and “valleys” in your skin. These type of scars need to treated by a Dermatologists. The best technology for that is today the fractional microneedle radiofrequency (RF) that uses very thin needles to heat the lower layer of the skin to produce new collagen. One of the best technologies to  check in this  category is Endymed's Intensif treatment system.

ProFractional Therapy

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
Acne scars are best treated with a fractionally ablative laser. Sciton's ProFractional Therapy is an Erbium: YAG laser that gives the physician very precise depth control and optional coagulation of the ablated tissue.  The wound-healing process produces fibroblasts that generate new collagen, plumping the skin and correcting skin imperfections. In fractional resurfacing, the laser removes pinpoint columns of skin, leaving the surrounding tissue intact to promote rapid healing. CO2 lasers come with a high risk of hypopigmentation and a longer downtime than Erbium. Hope this helps!

A combination of treatments works best for acne scar revision.

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
The Fractional Co2 Laser is a great option for scars, however, where acne scars are deeply tethered to underlying tissue, lasers alone may not be adequate. It is common to combine procedures like subcision, punch lifting of the scars, TCA CROSS, PRP , spot dermabrasion etc  to get a better overall improvement.
Good luck!

Acne Scarring

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
There are a few different lasers that can treat acne scarring. The most commonly used lasers are the Pixel and the Fraxel laser. The Pixel is a one time treatment but has about 7-10 days downtime after, the Fraxel has no downtime but needs to be repeated monthly for a series of 4-6 treatments. After either treatment you need to wear sunblock daily. Depending on the type of scars you have your doctor can suggest which treatment will work best.
