Acne Scar Removal

Medically Reviewed April 2023, by Dr. Ayad Harb, one of the world's leading plastic surgeons

What Are Acne Scars?

Acne scars are a widespread and often distressing dermatological issue that occurs following the healing of acne lesions. The scars are the result of inflamed blemishes caused by skin pores filled with excess oil, dead skin cells, and bacteria. Depending on the depth and severity of the break in the follicle wall, these scars can vary widely in appearance and impact.

When the rupture occurs near the skin's surface, the lesion is usually minor and heals quickly. However, when the break is deep, infected material can spill into surrounding tissue, creating deeper and more lasting lesions. In the skin's attempt to repair these wounds, new collagen fibers form. These repairs may not replicate the original skin's smoothness, resulting in the visible mark we recognize as a scar.

The type and severity of acne scars depend on multiple factors, including the nature of the acne, the individual's skin type, age, and the approach taken to treat the acne. Genetics can also play a significant role, with some people being more prone to scarring than others.

There are two primary categories of acne scars: atrophic and hypertrophic. Atrophic scars are characterized by a loss of tissue, often appearing sunken or depressed, while hypertrophic scars involve an overgrowth of tissue, leading to raised areas on the skin's surface.

The physical appearance of acne scars is only one aspect of their impact. The psychological toll can be equally, if not more, significant. These scars can greatly affect a person's self-esteem, confidence, and overall emotional well-being. In severe cases, they can even lead to depression or anxiety.

The treatment of acne scars is complex and requires a comprehensive understanding of the underlying causes, as well as the specific characteristics of the scars themselves. Various treatment options exist, ranging from topical creams to more invasive surgical procedures. The choice of treatment must be individualized, taking into consideration the type and severity of the scars, the patient's expectations, and the potential risks and benefits of the selected approach.

Acne scars represent a multifaceted challenge in dermatology, requiring a blend of clinical expertise, patient empathy, and technological innovation. Ongoing research and advances in treatment modalities continue to provide new avenues for successful management, offering hope to those suffering from this pervasive condition. Regular consultation with a dermatologist or qualified skin care professional is crucial for accurate diagnosis, proper guidance, and tailored treatment to achieve optimal results.

Types of Acne Scars

Ice-Pick Scars

Ice-pick scars are a distinctive form of scarring often associated with acne, particularly cystic acne. These scars are named for their deep, narrow appearance, resembling the hole made by an ice pick. Understanding their characteristics, causes, and available treatments requires a nuanced approach.

Ice-pick scars are deep, narrow, sharply defined scars that extend into the dermis or even deeper into the subcutaneous layer. Typically, these scars appear as small yet profound pits, giving the skin's surface a pitted, uneven appearance. The depth and sharp edges of these scars make them particularly noticeable and often challenging to treat.

The development of ice-pick scars stems from severe inflammation that occurs deep within the skin, commonly caused by cystic acne. When a cyst or nodule ruptures, infected material can spill out into surrounding tissues, creating a tract that leaves behind a scar as it heals. This healing process can result in a scar with a very narrow opening on the skin's surface, but with a deep and broad underlying depression.

The noticeable appearance of ice-pick scars can cause significant psychological distress. These prominent scars may lead to decreased self-esteem, social withdrawal, and even depression in some individuals. Understanding and acknowledging the emotional impact is essential in managing and treating the condition.

The treatment of ice-pick scars often requires a multifaceted and tailored approach due to their depth and distinct appearance. Common treatments include punch excision, a minor surgical procedure that involves cutting out the scar and stitching the wound, leading to a smoother, more even surface. Laser resurfacing can be used to remove the top layer of the scarred skin, encouraging the growth of healthy new skin. Chemical peels may be effective in treating shallower ice-pick scars by removing the outer layers of skin and stimulating collagen production. Microneedling involves using tiny needles to create controlled injuries to the skin, prompting it to heal and produce more collagen.

Ice-pick scars are complex and often require specialized treatment. Consultation with a dermatologist or qualified skin care professional is essential for accurate diagnosis and appropriate intervention. Early intervention can reduce the severity of these scars, but even well-established scars can often be significantly improved with the right combination of treatments. The journey to healing may be gradual, but with persistence and professional guidance, substantial improvement is attainable.

Rolling Scars

Rolling scars are a type of atrophic scar that can be especially challenging to address due to their broad, undulating appearance. These scars present a unique set of characteristics and considerations for both patients and healthcare providers.

Characteristics and Appearance: Rolling scars are defined by their broad depressions and undulating appearance in the skin, often resembling a wave-like pattern. These depressions have sloping edges that merge with the surrounding skin, creating an uneven surface. Unlike other scar types that may have defined borders, rolling scars tend to blend with the surrounding skin, making them less distinct but still noticeable.

These scars often result from chronic inflammatory acne conditions that cause damage to the collagen in the dermis. Fibrous bands of tissue develop between the skin and subcutaneous layer, pulling the epidermis into the underlying structures. This pulling creates the rolling or wave-like appearance characteristic of these scars.

Like other types of scarring, rolling scars can have a significant emotional impact. Even though they might be less noticeable than other scar types, their presence can lead to self-consciousness and a reduction in overall self-esteem. This impact emphasizes the need for compassionate care and effective treatment.

The treatment of rolling scars requires specialized techniques to address their unique structure. Subcision is a common method used to cut the fibrous strands beneath the skin, allowing the scar to lift and the surface to even out. Laser resurfacing is another popular treatment, with several types of lasers offering varying levels of skin resurfacing and collagen stimulation. Fillers can be used to raise the depressed areas of the skin, providing a smoother appearance. Combining these treatments may provide the most effective approach for many patients, depending on the depth and severity of the scars.

Rolling scars present a distinct challenge within the field of dermatology. Their unique appearance, underlying causes, and potential psychological impacts require a comprehensive approach to diagnosis and treatment. With careful assessment and a tailored combination of available treatments, significant improvement in the appearance and texture of rolling scars is possible. Collaboration with a dermatologist or qualified skin care professional ensures an understanding of the individual's specific needs and the creation of a treatment plan to provide the best possible outcomes.

Boxcar Scars

Boxcar scars are another type of atrophic acne scar that are often linked with the healing of acne vulgaris. These scars have distinctive features, impacts, and treatment considerations that set them apart from other forms of acne scarring.

Boxcar scars are typically characterized by sharp, defined edges and a flat bottom, resembling the shape of an oblong or a box. These scars can vary in size but are generally round or oval with vertical sides, giving a 'punched-out' appearance. Unlike rolling scars, which have sloping edges, boxcar scars have more distinct borders, making them stand out more clearly against the surrounding skin.

Boxcar scars usually form after inflammatory acne, especially when it affects the deeper layers of the skin. The inflammation damages the collagen, leading to a loss of support in the affected area. When the acne lesion heals, it leaves behind a depressed area with clearly defined edges, resulting in the characteristic boxcar shape.

The appearance of boxcar scars can cause a profound psychological impact on individuals. These scars can be prominent and draw attention, leading to feelings of self-consciousness, embarrassment, and a reduction in overall confidence. Recognizing and addressing this emotional aspect is an essential part of the overall treatment plan.

Treatment for boxcar scars typically involves methods that stimulate collagen production or remove layers of skin to reduce the depth of the scar. This can include laser resurfacing, which uses focused light energy to remove damaged skin cells, encouraging new cell growth. Microneedling can stimulate collagen production, helping to lift the scarred area. For deeper scars, punch excision may be used, where the scar is surgically removed and the wound closed with stitches. Fillers can also be injected to raise the scar to the level of the surrounding skin.

Boxcar scars present both physical and emotional challenges to those who bear them. With the right combination of therapies, significant improvement can be achieved. The importance of early intervention, proper diagnosis, and an individualized treatment approach cannot be overstated. Collaboration with a qualified dermatologist or skincare professional ensures the creation of an effective treatment plan, helping individuals regain both smoother skin and greater confidence. The process may require time and commitment, but the results can be life-changing for those affected by boxcar scars.

Atrophic Scars

Atrophic scars are a common type of acne scarring characterized by a loss of tissue, leading to a depressed or sunken appearance. Unlike hypertrophic scars, which are raised, atrophic scars lie below the surrounding skin surface. They represent a significant challenge in both understanding and treatment, given their distinctive characteristics and potential psychological impacts.

Atrophic scars manifest as depressions in the skin and are typically classified into three main subtypes: ice pick, rolling, and boxcar scars. Each of these has unique features, but all result from a loss of collagen and tissue in the affected area. These depressions can create a pitted or uneven skin texture, often leading to cosmetic concerns.

Atrophic scars generally form following inflammatory acne or other skin injuries that lead to a loss of collagen. During the healing process, if the body produces insufficient collagen to replace what was lost, it can result in a depressed scar. Various factors, including the severity of the initial inflammation, genetic predisposition, and delays in treatment, can contribute to the formation of atrophic scars.

The physical manifestations of atrophic scars can significantly affect an individual's self-perception and confidence. The visibility of these scars, especially on the face, can lead to feelings of embarrassment or self-consciousness. This highlights the importance of an empathetic and comprehensive approach to care.

Treating atrophic scars requires a customized approach based on the specific type and severity of scarring. Options may include dermal fillers, which can temporarily elevate the scar to the level of surrounding skin, laser therapy to resurface the skin and stimulate collagen production, and microneedling, which also promotes collagen synthesis. Chemical peels and surgical methods such as subcision may be utilized to release fibrous bands pulling the skin downward and encourage natural collagen production.

Atrophic scars represent a complex and multifaceted challenge in dermatology and aesthetic medicine. Proper diagnosis, early intervention, and a tailored treatment plan are crucial to achieving the best possible outcomes. Patients seeking treatment for atrophic scars should consult with a dermatologist or qualified skincare professional to develop a plan that addresses both the physical scars and potential emotional impacts. With the right approach, significant improvement in appearance and self-esteem can be achieved, helping individuals move beyond the lasting effects of acne or other skin traumas.

Hypertrophic Scars

Hypertrophic scars are a form of raised scar that occurs when the body overproduces collagen during the wound healing process. Unlike atrophic scars, which result in depressions in the skin, hypertrophic scars create a raised and often rigid area that can be both visually prominent and physically uncomfortable. Understanding the complexity of these scars is essential in formulating effective treatment strategies.

Hypertrophic scars are thickened, raised, and often reddish in color. They typically stay within the boundaries of the original wound but may extend slightly beyond those borders. The surface may be rough, irregular, and may feel firmer to the touch compared to the surrounding skin. Over time, the color may fade, but the raised appearance often remains.

These scars typically form following a skin injury, surgical incision, or severe acne inflammation. When the healing process results in an overproduction of collagen, it leads to a dense accumulation of tissue. Factors such as genetics, wound infection, tension on the wound, 

and even individual healing characteristics can influence the development of hypertrophic scars.

The physical appearance of hypertrophic scars can lead to self-consciousness and dissatisfaction with one's appearance. Additionally, these scars may cause itching or discomfort, adding to the distress. Understanding these physical and emotional aspects is vital in addressing the needs of those affected by hypertrophic scars.

Treatment for hypertrophic scars often involves a combination of methods to both reduce the appearance and alleviate any associated symptoms. Options may include silicone gel sheeting to flatten the scar, steroid injections to reduce inflammation and slow collagen production, and laser therapy to improve color and texture. Surgical revision may be considered in more severe cases, where the scar tissue is removed and the wound is carefully re-closed. Cryotherapy, pressure therapy, and even radiation in extreme cases might also be employed.

Hypertrophic scars present both a physical and psychological challenge, requiring a multidisciplinary approach for effective management. Early intervention, ongoing assessment, and a tailored treatment plan developed in collaboration with a dermatologist or qualified skincare professional can significantly improve both the appearance and comfort of hypertrophic scars. Advances in both understanding and treatment offer hope for those living with these scars, providing opportunities for enhanced self-esteem and a better quality of life. Like many skin conditions, hypertrophic scars require time, patience, and appropriate professional care, but with the right approach, meaningful improvements can be achieved.

Acne Scar Treatments


Morpheus8 is an innovative, minimally invasive treatment that combines microneedling with radiofrequency energy to target and remodel underlying collagen. It has become an increasingly popular method for treating acne scars, including those challenging to manage like deep atrophic scars.

Morpheus8 utilizes tiny needles that penetrate the skin's surface, delivering radiofrequency energy to the deeper layers.

Microneedling is a minimally invasive procedure that has gained popularity for its effectiveness in treating various skin imperfections, including acne scars. Using fine needles, microneedling induces controlled micro-injuries to stimulate the skin's natural healing process.

The procedure involves a device equipped with fine needles that create tiny punctures in the skin's surface. These micro-injuries stimulate the body's natural healing response, leading to increased collagen and elastin production, essential for skin regeneration and scar reduction.

Microneedling offers a versatile treatment for various types of acne scars, improving skin texture, reducing scar visibility, and enhancing overall skin appearance. The procedure is typically well-tolerated, with minimal downtime.

After applying a numbing cream, the practitioner uses the microneedling device to treat the targeted areas. The procedure generally takes 30 minutes to an hour, depending on the treatment's extent.

Some redness and swelling may occur post-treatment but typically resolve within a couple of days. Results become visible as the skin heals, with noticeable improvement in a few weeks. Multiple sessions may be needed for more pronounced scars.

Microneedling has become a standard treatment option for acne scars, appealing to many for its non-surgical nature and ability to deliver noticeable improvements. Patients interested in this treatment should consult with a qualified provider to ensure an individualized approach that meets their specific needs and expectations.

Plasma (PRP)

Platelet-Rich Plasma (PRP) therapy, commonly known as Plasma therapy, is an innovative treatment that harnesses the power of the body's platelets to rejuvenate the skin and improve the appearance of acne scars.

PRP is derived from the patient's blood, separated to concentrate the platelets, which are rich in growth factors. When injected into the scarred areas, these growth factors stimulate collagen production and cellular regeneration, helping to reduce the appearance of scars.

PRP therapy offers a natural, personalized approach to acne scar treatment. It can be used alone or in combination with other treatments like microneedling or laser therapy, enhancing their effects. It has been shown to improve skin texture, tone, and overall appearance.

Blood is drawn from the patient and processed to isolate the platelet-rich plasma. This concentrated plasma is then injected into the scarred areas, either alone or following other treatments like microneedling. The procedure typically takes about an hour.

There may be some minor discomfort and bruising at the injection sites, but these generally resolve quickly. Results begin to show in a few weeks and continue to improve over several months. Repeat treatments may be recommended for deeper scars.

Plasma (PRP) therapy provides a promising option for those seeking a more natural and personalized treatment for acne scars. Its versatility and compatibility with other treatments make it an attractive choice for many patients. As with any procedure, consultation with a qualified professional is crucial for proper assessment and tailored treatment planning.

Chemical Peel

Chemical peels are a well-established method for treating various skin concerns, including acne scars. Utilizing different acid solutions, chemical peels remove the top layers of damaged skin, promoting new skin growth and reducing the appearance of scars.

Chemical peels use specific acid solutions applied to the skin to dissolve the outermost layers of dead and damaged skin cells. The depth of the peel and the type of acid used are tailored to the individual's skin type, scarring severity, and desired results.

Chemical peels can effectively reduce the appearance of acne scars, improve skin texture, and enhance overall skin radiance. They are available in various strengths, from superficial peels requiring minimal downtime to deeper peels offering more dramatic results.

After thoroughly cleansing the skin, the practitioner applies the chemical solution, allowing it to penetrate to the desired depth. The solution is then neutralized and removed. Depending on the peel's strength, the procedure may take anywhere from 15 minutes to an hour.

Recovery varies with the peel's strength, with superficial peels requiring little to no downtime and deeper peels requiring a more extended recovery period. Results become visible as the skin heals and rejuvenates, with ongoing improvements seen over several weeks.

Chemical peels represent a versatile and effective treatment for acne scars, catering to a wide range of skin types and scar conditions. Careful assessment and collaboration with a skilled provider are essential to select the appropriate peel type and strength, ensuring the best possible results tailored to individual needs and preferences.
