Common Types of Acne Scars

Common types of acne scar


Acne, a prevalent skin condition, impacts millions of people across the globe, and its effects extend beyond the physical realm, often leaving emotional scars as well.

Beyond the discomfort and self-consciousness caused by the presence of pimples, it’s the enduring aftermath of acne in the form of scars that can truly affect one’s confidence and self-esteem.

These acne scars persist long after the blemishes themselves have cleared, serving as a constant reminder of the battle against acne.

To better comprehend the complexities of acne scars and their various manifestations, it’s crucial to distinguish between the common types of acne scars. This understanding serves as the first step on the path to finding the most suitable treatment and ultimately achieving the clearer, smoother skin you desire.

Acne and the Scars Left Behind

Acne occurs when hair follicles become clogged with oil and dead skin cells, leading to the formation of pimples, whiteheads, or blackheads. In some cases, the inflammation associated with acne can damage the skin’s collagen, resulting in the formation of scars. These scars can take various forms, each with its unique characteristics.

Rolling Scars

1. Rolling Scars

Rolling scars, a specific type of acne scar, exhibit distinctive characteristics that set them apart from other scar types. These scars are characterized by their shallow depth and a unique wave-like appearance on the skin’s surface. Unlike some other scar types that may have more defined edges or depressions, rolling scars often have a gradual transition between the scar tissue and the surrounding skin.

The development of rolling scars is typically associated with damage to the deeper layers of the skin, particularly the dermis. This damage can be a consequence of severe acne breakouts or inflammatory conditions that affect the skin.

In such cases, the loss of collagen, a crucial structural protein in the skin, plays a significant role. As collagen provides support to the skin, its reduction in the deeper layers causes a noticeable change in skin texture and contour.

This loss of structural support beneath the skin’s surface results in the rolling or undulating appearance characteristic of these scars. The skin seems to have small, gentle slopes and valleys, creating an uneven and textured look. 

Ice Pick

2. Ice Pick Scars

Ice pick scars represent a distinct category among acne scars, characterized by their narrow, deep, and pitted appearance. These scars often resemble tiny, well-defined holes or punctures on the skin’s surface, creating a texture that is notably different from the surrounding healthy skin.

The formation of ice pick scars is primarily attributed to the loss of tissue beneath the skin’s surface. This tissue loss occurs as a consequence of severe inflammation or damage caused by acne. When the skin undergoes this damage, it can result in the formation of these deep and narrow scars.

What sets ice pick scars apart from other scar types is their depth; they extend deep into the skin’s layers, making them particularly challenging to address with conventional over-the-counter skincare products.

Due to their profound and localized nature, these scars often require specialised treatments administered by dermatological professionals. These treatments aim to stimulate collagen production, fill in the scar’s depressed areas, and promote overall skin rejuvenation, ultimately helping to improve the appearance of ice pick scars and restore smoother, more even skin.


3. Boxcar Scars

Boxcar scars represent a specific category of acne scars, and their name aptly describes their appearance. These scars manifest on the skin as depressions with well-defined edges that closely resemble the shape of a boxcar or a rectangular box. While they may not be as deep or narrow as “ice pick” scars, they are wider and more distinct, making them easily recognizable. These scars are characterized by their flat bottoms and sharply defined vertical walls, creating a texture that differs significantly from the surrounding healthy skin.

The formation of boxcar scars is intricately linked to the aftermath of inflammatory acne. When the skin experiences inflammatory acne lesions or severe pimples, the body’s natural healing process can sometimes result in the production of insufficient collagen.

Collagen is essential for maintaining skin’s structure and elasticity. When its production is inadequate, it leads to an imbalance in tissue repair, ultimately resulting in these depressions with distinct edges.


Keloid Hyperthropic Scars

4. Keloid & Hyperthropic Scars

Keloid scars and hypertrophic scars are unique and often challenging forms of scarring that can result from the skin’s natural healing process, particularly in individuals who are predisposed to these conditions. These scars are distinct from other scar types due to their raised appearance and the excessive production of collagen in response to skin damage.

Keloid scars, in particular, present as raised and elevated growths that extend well beyond the boundaries of the original acne blemish or injury. They can become significantly larger than the initial wound, creating a noticeable and sometimes uncomfortable prominence on the skin’s surface. Keloids are characterized by their tendency to grow beyond the original injury site and can even be larger than the surrounding healthy tissue.

On the other hand, hypertrophic scars share the raised quality with keloids but typically remain confined within the limits of the initial injury or acne blemish. While they don’t extend as extensively as keloids, they can still appear as noticeable raised areas on the skin.


Back Acne Scars

5. Back Acne Scars

Back acne scars, often referred to as “bacne” scars, can be just as challenging to treat as facial scars. Unlike facial acne scars, which are more commonly discussed, back acne scars are equally troublesome but often overlooked. The skin on the back is naturally thicker than that on the face, which presents unique challenges when it comes to scar removal and treatment.

One of the significant differences lies in the thickness of the skin. Back skin is generally thicker and contains larger sebaceous glands compared to facial skin. These larger glands produce more oil, making the back prone to acne breakouts. When these breakouts occur, they can lead to inflammation, pus-filled pimples, and ultimately, scarring.

Back acne scars can manifest in various types, including depressed scars like boxcar or ice pick scars, or raised scars like keloids or hypertrophic scars. The thicker skin on the back influences the type and appearance of these scars, making their treatment and removal more complex.

Post Inflammatory Hyperpigmentation<br />

6. Post-inflammatory hyperpigmentation (PIH)

Post-inflammatory hyperpigmentation (PIH) is a distinct skin concern that, while not classified as a scar, frequently occurs as a consequence of acne breakouts. This condition is characterized by the development of dark or discoloured spots in the areas where previous acne blemishes once resided. While these spots are not permanent, they can persist for extended periods, often months or even years, creating a visible and sometimes persistent reminder of past acne episodes.

PIH primarily affects the skin’s pigmentation, resulting in the formation of these darker spots. The process involves an overproduction of melanin, the pigment responsible for skin colouration. When the skin experiences inflammation or injury, as is the case with acne, melanin production can become irregular and concentrated in certain areas, leading to the formation of these spots.

One notable aspect of PIH is its higher prevalence in individuals with darker skin tones. People with more melanin in their skin are more susceptible to developing these dark spots following acne breakouts. While PIH is not a permanent condition, addressing it can be a gradual process. 

Factors Influencing Scar Formation

The development and severity of acne scars are influenced by a range of factors, and understanding these factors is crucial for effective prevention and management. Here are the key factors that play a role in the likelihood and severity of acne scars:

1.Genetics: Genetic predisposition can significantly impact an individual’s tendency to develop severe acne and, consequently, scarring. If there is a family history of acne scarring, there may be an increased risk for subsequent generations.

2.Acne Severity: The severity of acne itself is a major determinant of scarring risk. In general, the more severe and persistent the acne, the greater the likelihood of scarring. This includes conditions like cystic acne, which can lead to more pronounced scars.

3.Skin Type: Skin type plays a role in acne development and scarring. People with oilier skin tend to be more prone to acne breakouts, as excess sebum production can clog pores and lead to inflammation. This increased susceptibility to acne can, in turn, elevate the risk of scarring.

4.Picking and Squeezing: Engaging in the habit of picking, squeezing, or manipulating acne lesions is a common mistake that can worsen inflammation and increase the risk of scarring. Squeezing pimples can push bacteria and debris deeper into the skin, potentially leading to more significant damage.

5.Delayed Treatment: Promptly addressing acne and seeking professional treatment is crucial in minimizing the risk of scarring. Delaying treatment allows acne to worsen, potentially leading to more extensive inflammation and tissue damage. Early intervention with appropriate skincare and medical treatments can significantly reduce scarring risk.
