What Are the Most Common Types of Acne Scars?

Acne is more than just a temporary skin issue—it can leave behind long-lasting scars that affect both appearance and self-confidence. For many individuals, the struggle doesn't end when the acne clears. Acne scars, particularly if untreated, can become permanent marks that are challenging to conceal or reverse without professional care. These scars form when the skin's natural healing process is disrupted, usually due to inflammation, excess oil production, or trauma to the affected area.

Why Do Acne Scars Develop?

The Role of Inflammation and Healing

Scarring is the result of deep inflammation within the dermis, which damages the tissue. When a pore becomes clogged with excess oil, dead skin, or bacteria, the follicle wall can break. If the rupture is deep, it affects surrounding skin tissue, prompting the body to produce collagen to repair the damage. An imbalance in collagen—either too much or too little—can lead to different scar types.

Picking and Popping: A Major Cause

Manually popping pimples or picking at acne significantly increases the risk of scars. It delays healing, introduces bacteria, and worsens inflammation, making the post-acne aftermath more visible and persistent.

Atrophic Acne Scars: The Most Common Category

Atrophic scars are the most prevalent type and are characterized by a loss of skin tissue, giving the skin a sunken or pitted appearance. These scars typically result from severe acne or prolonged inflammation.

Ice Pick Scars

Ice pick scars are deep, narrow, and extend into the dermis. They resemble tiny puncture wounds or holes in the skin and are most commonly found on the cheeks. These scars are among the most difficult to treat due to their depth, often requiring a combination of advanced resurfacing and collagen-stimulating treatments for visible improvement.

Boxcar scars

Boxcar scars are broad, rectangular depressions with sharply defined edges. They are typically found on the lower cheeks and jawline, where the skin is thicker. These scars develop when an inflammatory breakout destroys collagen, leaving behind a crater-like depression.

Rolling Scars

Rolling scars have a wave-like, undulating appearance caused by fibrous bands of tissue forming between the skin and subcutaneous tissue. These bands pull the epidermis inward, creating a rolling texture. Unlike boxcar or ice pick scars, rolling scars have a softer, more sloped edge, but their appearance can become more pronounced with age due to collagen loss.

Hypertrophic and Keloid Scars

Not all acne scars result from a loss of tissue. Hypertrophic and keloid scars are raised scars caused by an overproduction of collagen during the healing process.

Hypertrophic Scars

Hypertrophic scars stay within the boundary of the original wound and tend to be red or pink and firm to the touch. They may gradually flatten over time but often remain raised without treatment. These scars are more common on the chest, shoulders, and back.

Keloid Scars

Keloids extend beyond the original acne site and can continue to grow. These thick, rubbery scars may be darker than the surrounding skin and often cause itching or discomfort. They’re more common in individuals with darker skin tones and require careful management to prevent recurrence.

Post-Inflammatory Hyperpigmentation (PIH) and Erythema

While not technically scars, post-inflammatory hyperpigmentation and erythema are common aftermaths of acne that mimic scarring.

Hyperpigmentation

Post-inflammatory hyperpigmentation occurs when acne heals and leaves behind flat, dark spots. These marks are more prominent in individuals with medium to dark skin tones. Though not true scars, they can linger for months and often respond well to brightening agents and gentle exfoliation techniques.

Erythema

Post-inflammatory erythema is characterized by red or pink spots that remain after active acne has resolved. It is more common in individuals with fair skin. These marks are caused by damaged capillaries and can take time to fade unless targeted by vascular-specific treatments.

Factors Influencing Scar Type and Severity

Genetics and Skin Type

A person’s genetic makeup plays a crucial role in how their skin reacts to inflammation. Some individuals are more prone to scarring due to their skin’s healing tendencies, while others may escape with minimal marks. Additionally, skin tone influences whether one experiences more hyperpigmentation or textural scarring.

Acne Severity and Duration

The severity of acne and how long it remains untreated directly correlates with scarring risk. Deep, cystic acne is more likely to leave behind atrophic or raised scars compared to mild acne. Prompt and appropriate intervention can help prevent permanent damage.

Age and Skin Elasticity

As skin ages, its ability to repair and produce collagen decreases. This reduced elasticity makes scars more pronounced and harder to treat. Younger skin generally heals faster and more efficiently, reducing long-term visible damage.

Professional Treatment Options for Acne Scars

Acne scar management involves a personalized plan tailored to the scar type and skin condition. Treatments often combine modalities for maximum effectiveness.

Microneedling and RF Microneedling

These procedures create controlled micro-injuries to the skin, stimulating collagen and elastin production. They are particularly effective for rolling and boxcar scars.

Laser Resurfacing

Laser therapies work by removing the damaged outer skin layers and stimulating the growth of new, smoother skin. Fractional lasers are especially effective for atrophic scars.

Chemical Peels

Chemical peels exfoliate the top layers of skin and can help reduce discoloration and minor scarring. Deeper peels may target more entrenched textural concerns with downtime.

Subcision

This technique involves breaking up the fibrous bands underneath rolling scars, allowing the skin to rise and create a smoother surface.

Final Thoughts

Identifying your acne scar type allows you to make more informed decisions about your skincare journey. While the scars may feel permanent, modern techniques offer transformative outcomes for nearly all types of acne-related damage. Addressing acne scars is not just about aesthetics—it’s about reclaiming your confidence and comfort in your skin.
