Types of Acne Scars: A Complete Guide to Identification, Causes & Treatment

Acne scars develop when inflamed breakouts damage the skin's collagen during healing. The main types of acne scars include ice pick, boxcar, rolling, hypertrophic, and keloid scars. Identifying the scar type is essential because each responds differently to skincare and professional treatments, making accurate diagnosis the first step toward effective improvement.

Acne doesn't always end when a breakout heals. The types of acne scars left behind can affect your skin's texture and confidence long after acne is gone. Understanding how these scars form and how they're treated helps you make informed skincare decisions. Along with expert treatments, maintaining a healthy skincare routine with Justhuman's science-backed skincare can support stronger, healthier-looking skin throughout your recovery journey. If your skin also tends to be oily, choosing suitable oily skin care products can help keep breakouts and future scarring in check.

What Are Acne Scars?

Acne scars are permanent changes in the skin that occur when inflamed acne lesions damage the deeper layers of the skin. As the skin repairs itself, collagen production may become uneven, resulting in either depressed or raised scars.

It's important to distinguish acne scars from post-acne marks. While acne marks are temporary discoloration that gradually fades, acne scars involve structural changes to the skin and usually require targeted treatment. Understanding the causes of pigmentation can also help you tell discoloration apart from true textural scarring.

Why Do Acne Scars Form?

Your skin naturally produces collagen to repair damaged tissue. However, severe inflammation caused by acne can disrupt this healing process. This disruption is also part of why learning how to reduce pigmentation on face often goes hand in hand with managing acne-related skin changes.

Several factors increase the likelihood of scarring:

• Deep inflammatory acne

• Picking or squeezing pimples

• Delayed acne treatment

• Genetics

• Prolonged skin inflammation

• Excess or insufficient collagen production

When too little collagen is produced, the skin develops indented scars. Too much collagen creates raised scars.

The Main Types of Acne Scars

Dermatologists broadly classify types of acne scars into two categories:

• Atrophic (depressed) scars

• Hypertrophic (raised) scars

Each type has unique characteristics and treatment approaches.

1. Ice Pick Scars

Ice pick scars are narrow, deep scars that extend into the skin, resembling tiny puncture marks made by a sharp object.

Characteristics

• Small openings

• Deep, V-shaped appearance

• Common on cheeks

• Difficult to treat without professional procedures

These scars usually develop after severe cystic acne damages collagen deep beneath the skin.

2. Boxcar Scars

Boxcar scars appear as broad, shallow depressions with clearly defined edges. Alongside professional treatment, applying a suitable pigmentation cream for face can help even out surrounding discoloration.

They commonly develop on the:

• Cheeks

• Temples

• Jawline

Unlike ice pick scars, boxcar scars are wider and less deep. Treatments such as microneedling, laser resurfacing, and chemical peels may help improve their appearance.

3. Rolling Scars

Rolling scars create a wave-like or uneven texture across the skin.

They occur when fibrous bands beneath the skin pull the surface downward, producing soft depressions with sloping edges.

Rolling scars often become more noticeable under certain lighting conditions because of the uneven skin surface. Using a targeted skin pigmentation cream can help minimise the appearance of any accompanying discoloration.

4. Hypertrophic Scars

Hypertrophic scars develop when the skin produces excessive collagen during healing.

These scars are:

• Raised

• Firm

• Confined to the original acne lesion

They most commonly occur on the chest, shoulders, back, and jawline.

5. Keloid Scars

Keloid scars are raised scars that continue growing beyond the boundaries of the original acne lesion.

They tend to be:

• Thick

• Smooth

• Elevated

• Larger than the original wound

Some individuals have a genetic tendency to develop keloids, making early acne management especially important.

Acne Scar Types at a Glance

How to Identify Your Acne Scar Type

Correctly identifying the types of acne scars helps determine the most appropriate treatment.

Ask yourself:

• Are the scars deep or shallow?

• Are they raised or depressed?

• Do they have sharp or sloping edges?

• Are they limited to the acne spot or extending beyond it?

While self-observation is useful, a dermatologist can provide an accurate diagnosis and recommend a personalised treatment plan.

How Are Different Types of Acne Scars Treated?

There isn't a single treatment that works for every scar type. The best results often come from combining multiple therapies based on the scar's depth and severity.

Common professional treatments include:

• Microneedling

• Fractional laser resurfacing

• Chemical peels

• TCA CROSS

• Subcision

• Dermal fillers

• Steroid injections for raised scars

Because the types of acne scars vary significantly, treatment plans are usually customised rather than one-size-fits-all.

Can Skincare Help?

Although skincare products cannot completely remove deep scars, they can improve the skin's overall appearance and support healing.

Ingredients commonly recommended include:

• Retinoids

• Niacinamide

• Vitamin C

• AHAs

• BHAs

• Ceramides

• Daily broad-spectrum sunscreen

These ingredients help maintain healthy skin, improve texture, and minimise post-acne pigmentation while complementing professional procedures. For nighttime care, a dedicated night cream for pigmentation can further support this process while you sleep.

Can You Prevent Acne Scars?

Preventing acne scars starts with managing active acne early.

Follow these habits:

• Treat acne promptly.

• Avoid popping or picking pimples.

• Cleanse your skin gently.

• Use non-comedogenic skincare.

• Wear sunscreen every day.

• Stay consistent with your skincare routine.

Early intervention significantly reduces the risk of developing permanent types of acne scars.

Common Myths About Acne Scars

Many misconceptions surround acne scarring. Understanding the facts helps set realistic expectations.

Myth: Acne scars disappear on their own.

Fact: True scars rarely fade completely without treatment.

Myth: Home remedies can erase deep scars.

Fact: Natural remedies may soothe the skin but cannot rebuild lost collagen. For visible discoloration, however, a good pigmentation removal cream can still make a noticeable difference over time.

Myth: Only severe acne causes scars.

Fact: Even moderate acne can leave scars if inflammation is prolonged or lesions are picked.

Myth: All acne scars look the same.

Fact: Different types of acne scars require different treatment approaches.

When Should You See a Dermatologist?

Professional guidance is recommended if:

• You have deep or widespread scars.

• Acne continues despite treatment.

• Your scars affect your confidence.

• You're unsure which scar type you have.

• You want a personalised treatment plan.

Early evaluation can improve treatment outcomes and prevent additional scarring.
