Acne-Related Pockmarks: Causes and Ways to Manage Them

Important Notice: All treatments and skincare approaches mentioned have varying individual responses. No specific outcomes can be guaranteed. Professional consultation is recommended for personalized assessment.

Learn why pockmarks, a type of atrophic acne scar, form from collagen loss due to inflammation, and learn about professional and at-home treatments available for addressing skin texture concerns.

What Are Pockmarks

Pockmarks are deep, pitted scars that create a noticeable indentation or depression in the skin's surface. These marks are a lasting reminder of skin damage, most commonly resulting from severe acne. Unlike flat scars or simple discoloration, pockmarks are defined by their texture, giving the skin an uneven, "pitted" appearance. They form when the deeper layers of the skin are damaged and fail to regenerate properly during the healing process, leading to a permanent change in skin texture.

Understanding Atrophic Acne Scars

Pockmarks are a specific type of atrophic scar, which means they are indented and heal below the normal layer of skin tissue. This happens when there is a net loss of collagen at the site of an injury, such as an inflamed acne lesion. When a pimple, cyst, or nodule heals, the underlying support structure of the skin can be destroyed. If the body doesn't produce enough new collagen fibers to fill in the damaged area completely, a depressed scar forms, leaving behind the characteristic hollowed-out look of a pockmark.

Pockmarks vs Post-Inflammatory Hyperpigmentation (PIH)

It is crucial to distinguish between pockmarks and post-inflammatory hyperpigmentation (PIH), as they are often confused but require different management approaches. The key difference lies in skin texture versus skin color.

• Pockmarks are textural scars. They are physical indentations in the skin caused by a loss of collagen and damage to the dermal layer. You can feel a pockmark as a dip or pit on the skin's surface.

• Post-Inflammatory Hyperpigmentation (PIH) is a discoloration issue. It appears as flat red, brown, or dark spots on the skin where acne once was. PIH is caused by an overproduction of melanin during the skin's inflammatory response and does not involve any change in skin texture.

While both can occur after an acne breakout, treating a pockmark involves rebuilding collagen and resurfacing the skin, whereas managing PIH focuses on fading excess pigment.

The Three Main Types of Pockmarks

Pockmarks, a common type of atrophic or depressed scar, are not all the same. Identifying the specific type of scar is a crucial first step, as treatment approaches vary based on the specific scar type. They are generally categorized based on their depth, shape, and overall appearance.

Ice Pick Scars

Ice pick scars are deep, narrow pits that extend into the dermis. As their name suggests, they look as though the skin has been punctured with a tiny, sharp instrument. Typically less than 2 millimeters wide, their V-shaped appearance makes them considered relatively more difficult to treat by doctors due to their depth. These scars often result from an infected cyst or other deep blemish that has destroyed the skin tissue.

Boxcar Scars

Boxcar scars are broad, box-like depressions with sharply defined vertical edges. They can be shallow or deep and are usually round or oval in shape, similar in appearance to chickenpox scars. These atrophic scars form when an inflammatory breakout destroys collagen, leading to a loss of tissue support and leaving a sunken area on the skin. Their defined borders distinguish them from rolling scars.

Rolling Scars

Rolling scars create a wave-like or undulating texture on the skin's surface. These depressions are wide (often 4 to 5 millimeters) and have sloping, indistinct edges, unlike the sharp borders of boxcar scars. They are caused by may involve fibrous tissue formation under the skin that can affect surface texture. This tethering creates the characteristic "rolling" appearance.

Why Do Pockmarks Form After Acne

Pockmarks, a type of atrophic scar, are the result of the skin's healing process being disrupted after severe inflammation. When an acne lesion becomes deeply inflamed, it can damage the skin's underlying structure. As the skin attempts to repair itself, a loss of tissue may contribute to the formation of indented scars.

The Role of Inflammation in Collagen Destruction

The formation of a pockmark begins deep within the dermis, the skin's middle layer. Inflammatory acne, such as papules, pustules, nodules, and cysts, triggers an immune response, which may affect proteins such as collagen and elastin that contribute to the skin's structure. When the body tries to heal the wound left by the blemish, it sometimes fails to produce enough new collagen to fully replace the damaged tissue. This deficit in collagen results in a depression or pit on the skin's surface, creating the characteristic appearance of a pockmark.

Key Risk Factors for Developing Pockmarks

While genetics can play a role in your skin's tendency to scar, certain behaviors and conditions significantly increase the likelihood of developing pockmarks after an acne breakout.

Picking or Squeezing Blemishes

Manually picking, popping, or squeezing pimples is a primary contributor to scarring. This action intensifies inflammation, can push bacteria deeper into the dermis, and introduces new trauma to the skin. It disrupts the natural healing cycle and damages the delicate collagen fibers, which may affect the skin's ability to repair itself evenly.

Severe Inflammatory Acne Like Cysts and Nodules

Severe acne may increase the likelihood of scarring. Cysts and nodules are large, painful lesions that form deep within the skin. Their size and the significant inflammation they cause lead to more extensive destruction of skin tissue. This widespread damage makes it much more likely that the healing process will result in a permanent, indented scar.

Delaying Professional Acne Treatment

Allowing severe or persistent acne to continue without effective treatment prolongs the inflammatory state of the skin. The longer the inflammation lasts, the more damage it can do to the underlying collagen and elastin. Seeking timely advice from a doctor may help manage breakouts and inflammation, potentially reducing the chance of permanent scarring.

Professional Dermatological Options to Manage Pockmarks

While at-home skincare can improve skin texture, reducing the appearance of established pockmarks often requires professional intervention. A board-certified doctor can assess your specific scar types and recommend a personalized treatment plan. These in-clinic procedures are designed to address skin texture and appearance concerns. Treatment outcomes vary significantly among individuals.

Resurfacing Procedures for Skin Texture

Skin resurfacing treatments work by removing the damaged outer layers of the skin (epidermis) and heating the underlying layer (dermis). This process is designed to promote cellular renewal and new skin formation.

Laser Resurfacing

Laser treatments use focused light beams to improve skin texture. There are two primary categories:

• Ablative Lasers: These powerful lasers, such as CO2 and Erbium lasers, remove thin layers of skin with high precision. This approach can improve the appearance of shallow boxcar and rolling scars, though recovery time may be significant.

• Non-Ablative Lasers: These lasers, including fractional lasers like Fraxel, heat the tissue beneath the skin's surface to stimulate collagen production without removing the top layer. This generally involves less downtime, and multiple sessions may be required for noticeable improvement.

Chemical Peels

A chemical peel involves applying a chemical solution to the skin, which promotes exfoliation. Individual treatment responses vary significantly. For pockmarks, doctors use medium to deep peels with agents like Trichloroacetic Acid (TCA). A specialized technique called TCA CROSS (Chemical Reconstruction of Skin Scars) uses a high concentration of TCA applied directly into individual ice pick scars is used to promote collagen synthesis within the scar. Results may vary between individuals.

Dermabrasion and Microdermabrasion

These are mechanical exfoliation methods. Dermabrasion is an intensive procedure where a doctor uses a high-speed rotating tool to sand down the outer layers of skin, addresses overall skin texture concerns, with individual responses varying. It involves a longer recovery period. Microdermabrasion is a much gentler alternative that uses fine crystals or a diamond-tipped wand to polish the skin's surface. It can improve overall skin texture but has a minimal effect on deeper pockmarks.

Collagen Induction Therapies

These minimally invasive treatments create controlled micro-injuries in the skin. This triggers the body's natural wound-healing response, leading to the production of new collagen and elastin, which may support collagen production and improve the appearance of indented scars.

Microneedling

Also known as collagen induction therapy, microneedling uses a device with many fine, short needles to create tiny punctures in the skin. This process may remodel scar tissue and encourage the formation of new collagen. It is commonly used to address shallow rolling and boxcar scars over a series of treatments.

Radiofrequency Microneedling

This advanced procedure combines microneedling with radiofrequency (RF) energy. The needles deliver RF energy deep into the dermis, generating heat that may further stimulate collagen and elastin production compared to standard microneedling. This added heat may contribute to skin tightening and an improved appearance of atrophic scars.

Procedures Used for Deeper Scars

Deep, tethered, or narrow pockmarks often require more targeted procedures to correct the underlying structural issues causing the indentation.

Dermal Fillers

For some rolling and boxcar scars, a doctor can inject a dermal filler substance, such as hyaluronic acid, directly beneath the scar. This injection can help lift the depressed base of the scar, making it less noticeable compared to the surrounding skin. Effects vary among individuals and are temporary in nature, often lasting several months depending on the individual.

Subcision

Subcision is a minor surgical procedure commonly used for rolling scars, which are often anchored down by fibrous bands of tissue. A doctor inserts a special needle under the skin to cut and release these fibrous tethers. Releasing the scar allows the skin to lift and smooth out. Subcision is often combined with other treatments like fillers or microneedling to maximize collagen growth in the treated area.

Punch Excision

This technique is often regarded as a commonly used technique for deep ice pick scars and some narrow boxcar scars. A doctor uses a small, circular punch tool to surgically excise the individual scar. The small wound is then closed with a tiny suture, which may result in a small, flat line scar that is typically less noticeable and may fade with time.

At-Home Skincare to Improve the Appearance of Pockmarks

While professional dermatological treatments are commonly used to address pockmarks, while at-home skincare can play a supportive role in improving overall skin texture, a consistent at-home skincare routine can support these procedures and improve your skin's overall texture and tone. At-home care focuses on ingredients that encourage cell turnover, stimulate collagen, and protect the skin from further damage.

Topical Ingredients That May Help

Incorporating specific active ingredients into your daily regimen can help soften the appearance of shallow indented scars over time. Patience and consistency are key, as results from topical products are gradual.

Retinoids like Retinol and Tretinoin

Retinoids are derivatives of Vitamin A and are widely used in dermatology for skin rejuvenation They work by accelerating skin cell turnover and boosting collagen production. This mechanism supports cellular renewal processes as part of skincare routines. Over-the-counter options include retinol, while stronger versions like tretinoin require a prescription.

Exfoliating Acids like AHAs and BHAs

Chemical exfoliants help remove the top layer of dead skin cells, promoting a smoother and more even skin texture.

• Alpha Hydroxy Acids (AHAs): Ingredients like glycolic acid and lactic acid work on the skin's surface to improve texture and stimulate collagen. Regular use may help improve overall skin texture and make depressions appear less prominent.

• Beta Hydroxy Acids (BHAs): Salicylic acid is the most common BHA. It exfoliates both the skin's surface and the inside of pores, commonly used for managing active acne and may also support mild textural improvement.

Vitamin C for Brightening and Collagen Support

Vitamin C is an antioxidant that plays a role in collagen synthesis, which may help support the skin's underlying structure. Furthermore, it helps to brighten the complexion and fade post-inflammatory hyperpigmentation (PIH) that can surround pockmarks, which may reduce their overall visibility and contribute to a more even skin tone.

The Critical Role of Sunscreen in Scar Management

Sun protection is non-negotiable when managing any type of scar, including pockmarks. Ultraviolet (UV) radiation from the sun degrades existing collagen, which can counteract any progress made and potentially worsen the depth of atrophic scars. Sun exposure can also darken the skin within and around the scar, making it more noticeable.

Using a broad-spectrum sunscreen with an SPF of 30 or higher every day is essential. This step protects your skin from damage and is especially important when using retinoids or exfoliating acids, as these ingredients can increase your skin's sensitivity to the sun.

Ways to Reduce the Risk of Future Pockmarks

While many treatments can improve existing pockmarks, prevention remains the most effective strategy. By managing active acne and adopting healthy skin habits, you can significantly lower your risk of developing new atrophic scars.

Treat Active Acne Promptly

The longer severe, inflammatory acne persists, the greater the potential for permanent damage to the skin's underlying collagen structure. Addressing breakouts as soon as they appear is the first line of defense against future scarring.

• Address Mild Breakouts: For minor pimples, use over-the-counter spot treatments containing ingredients like salicylic acid or benzoyl peroxide to reduce inflammation quickly.

• Consult a Doctor for Severe Acne: For persistent or severe forms of acne, such as cysts and nodules, professional intervention is critical. A doctor can prescribe effective treatments to control inflammation before it has a chance to destroy skin tissue and cause scars.

Adopt a Hands-Off Policy for Your Face

Picking, squeezing, or attempting to "pop" pimples is one of the leading contributors to pockmark formation. This physical manipulation causes additional trauma to the skin, worsening inflammation and disrupting the natural healing process.

• Avoid Popping Blemishes: Squeezing a pimple can force bacteria and pus deeper into the dermis, intensifying the inflammatory response and increasing the likelihood of a depressed scar.

• Protect Healing Skin: Picking at a scab or healing blemish can remove new tissue and interfere with collagen regeneration, making a permanent indentation more likely. Instead, try using a hydrocolloid patch to cover the spot, which can help absorb fluid and prevent you from touching it.

Follow a Consistent and Gentle Skincare Routine

A supportive skincare routine helps maintain a healthy skin barrier, which can reduce the frequency of breakouts and promote better healing when they do occur. The key is to be gentle and avoid irritating the skin further.

• Cleanse Gently: Use a mild, pH-balanced cleanser to wash your face twice daily. Avoid harsh scrubs and abrasive tools that can cause micro-tears and aggravate inflammation.

• Keep Skin Hydrated: A well-hydrated skin barrier functions more effectively. Use a non-comedogenic moisturizer daily to lock in moisture without clogging pores.

• Prioritize Sun Protection: As mentioned previously, daily use of a broad-spectrum sunscreen is essential. UV radiation can break down collagen, impair the skin's healing ability, and make any discoloration from past acne more prominent.

When Consulting a Doctor May Be Helpful

While a consistent at-home skincare routine can support overall skin health, managing established pockmarks typically requires professional medical guidance. A board-certified doctor can provide an accurate diagnosis and create a treatment plan that is appropriate for your individual skin condition. It is highly recommended to seek a professional consultation in the following circumstances:

• You Have Severe or Persistent Acne: The most critical step in preventing future pockmarks is to control the underlying cause. If you have active cystic acne or nodular acne, a doctor can prescribe treatments that may help reduce inflammation and lower the risk of further scarring.

• Over-the-Counter Products Are Not Working: If you have used at-home treatments like retinols and exfoliating acids for several months without seeing a noticeable improvement in your skin's texture, it may indicate that professional evaluation could be helpful.

• Your Scars Are Deep or Widespread: Deep ice pick, boxcar, and rolling scars are structural changes within the dermis. Topical products are generally limited in addressing deeper structural changes. In such cases, a doctor may recommend procedures designed to improve skin texture.

• The Scars Affect Your Mental Well-being: The emotional and psychological impact of skin conditions is a valid reason to seek medical help. If your pockmarks are causing distress or affecting your self-confidence, a doctor can partner with you to find solutions.

• You Are Unsure About Your Condition: A professional can accurately identify the specific types of atrophic scars you have and distinguish them from other issues like post-inflammatory hyperpigmentation (PIH), helping you choose treatment options that are appropriate for your skin condition.

In summary, a doctor offers access to a range of medical options, from prescription medications to clinical procedures that may help improve the appearance of pockmarks.

Summary

Pockmarks are a form of atrophic, or indented, acne scar resulting from a loss of collagen during the skin's healing process. They are distinct from post-inflammatory hyperpigmentation (PIH), which involves discoloration rather than a change in skin texture. These scars typically present in three main forms: narrow ice pick scars, wide boxcar scars, and wavy rolling scars.

The primary cause of pockmarks is severe inflammatory acne, such as cysts and nodules, which destroys skin tissue. Key risk factors that increase the likelihood of scarring include picking or squeezing blemishes and delaying professional acne treatment. While these scars are permanent, their appearance may be improved with appropriate care.

A doctor can offer a range of treatment options tailored to the specific scar type. Professional options include resurfacing procedures like laser therapy and chemical peels, collagen-stimulating therapies like microneedling, and targeted methods for deeper scars such as dermal fillers and subcision. At-home care, including the use of retinoids, exfoliating acids, and vitamin C, can complement these treatments. Daily sunscreen use is an important part of supporting skin health and reducing the risk of further discoloration.

Ultimately, the best way to manage pockmarks is to prevent them. This involves treating active acne promptly, adopting a hands-off approach to blemishes, and following a consistent, gentle skincare routine. If you are struggling with severe acne or existing scars, consulting a board-certified doctor can be an important step in exploring options to support smoother-looking skin.
