Acne Scar Treatment

Acne scars are permanent structural changes within the skin that develop after inflammation damages the normal collagen framework. While some scars result primarily from collagen loss, others remain attached to deeper tissues by fibrous bands that pull the skin downward. Many patients also have a combination of scar types, making treatment considerably more complex than simply resurfacing the skin.

Because different scars develop in different ways, there is rarely a single treatment that is appropriate for every patient. Understanding how a scar formed is often the first step toward selecting the treatment most likely to improve it.

Most facial acne scars are atrophic (depressed) scars, meaning that collagen loss during healing leaves the skin with permanent depressions. These include rolling, boxcar, and icepick scars. Less commonly, acne can produce hypertrophic (raised) scars or keloids, which develop from excessive collagen production. This is more common on the upper back, chest, and shoulders, but can also occur on the face.

Additionally, most patients have several different scar types at the same time. Although the distinction is not always obvious, recognizing the type of scar often helps determine which treatment is likely to be most effective. Some patients also have enlarged pores, uneven skin texture, persistent redness, or discoloration that may require a different treatment approach than the scars themselves.

Rolling Scars
Rolling scars are gently sloping depressions that are often tethered beneath the skin by fibrous bands. Because of this tethering, treatments that simply resurface the skin typically provide only limited improvement if the underlying attachments are not first released. However, these scars frequently respond well to subcision.

Boxcar Scars
These are broader depressions with relatively well-defined edges. Depending on their depth, they may be treated with TCA-CROSS, punch elevation, laser resurfacing, or a combination of procedures. If deeper or tethered, these may also benefit from subcision.

Icepick Scars
These are narrow, deep, sharply defined scars that often respond best to TCA-CROSS when relatively superficial or to punch excision when deeper.

Hypertrophic Scars
Unlike the three previous categories of scars, hypertrophic scars and keloids develop because the skin produces too much collagen during healing. Because these scars form through a different healing process, treatment is also different and may include intralesional corticosteroid injections, silicone therapy, laser treatment, or other approaches that help to reduce excess collagen and flatten the scar.

Modern acne scar treatment often involves combining several complementary procedures, each designed to address a particular type of scar.

Subcision

Subcision is often the treatment of choice for rolling acne scars that remain tethered beneath the skin by fibrous scar tissue. By carefully releasing these fibrous bands, the skin is free to elevate while the body’s natural healing response gradually produces new collagen beneath the treated area. In many patients, additional procedures are then used to address other scar types.

TCA-CROSS
TCA-CROSS uses carefully placed high-strength trichloroacetic acid to stimulate collagen production within selected icepick and boxcar scars.

Punch Excision and Punch Elevation
Punch excision and punch elevation are minor surgical techniques that may improve carefully selected deep scars that are unlikely to respond adequately to collagen stimulation alone.

Laser Resurfacing
Fractional CO₂ laser resurfacing improves overall skin texture and softens the transition between scars and surrounding skin by stimulating additional collagen remodeling. In many patients, it is performed after deeper structural problems have already been addressed.

Although many patients search specifically for procedures such as subcision or TCA-CROSS, the most effective treatment depends on the type of scar being treated rather than the name of the procedure itself. Each procedure has unique advantages, and many patients benefit from combining more than one technique.

One of the most common questions we hear is, “What is the best acne scar treatment?”

In reality, the better question is, “What is the best treatment for this particular scar?”

We do not believe there is a single procedure that is right for every patient, nor do we recommend predetermined treatment packages. Every patient’s scars, skin, and healing response are different. Rather than repeating the same procedure simply because it was planned in advance, we reassess your progress after each treatment. If improvement continues, the procedure may be repeated. If progress begins to plateau, another treatment may be recommended instead.

Our goal is not to perform the greatest number of procedures. Our goal is to recommend the right procedure at the right time based on your individual scars. The best treatment depends on the scar – not on the device available in the office. Thus, each treatment plan is carefully tailored to the individual to ensure the most effective approach for their specific concerns.

Improving acne scars is usually a gradual process rather than a single event. Although individual procedures may take only minutes to perform, collagen remodeling continues beneath the skin for several months afterward.

Some patients achieve excellent improvement after only one or two procedures, while others benefit from a series of treatments performed over time. Because every patient heals differently, it is impossible to accurately predict the exact number of treatments needed before treatment begins.

We strive for meaningful, natural-looking improvement rather than perfection. Treatment often concludes when the remaining scars become mild enough that additional procedures would provide only minimal improvement compared with their cost and recovery.
