Treatment for Acne Scarring
Acne scarring refers to permanent changes in skin texture and appearance caused by inflammatory acne. When severe acne damages the deeper layers of the skin, the body’s wound-healing response may produce too little collagen, creating depressed or atrophic scars, or too much collagen, creating raised or hypertrophic scars. Atrophic scars, including ice pick, boxcar, and rolling scars, account for the majority of acne scars. Treatment may involve laser resurfacing, microneedling, subcision, dermal fillers, chemical peels, or a combination of methods for optimal results. Combination treatment is the norm because each atrophic scar type presents a different structural problem: rolling scars are tethered from below and need to be released, boxcar scars have defined edges that need resurfacing, and ice pick scars are too narrow and deep for either approach and are usually excised one at a time. Because many faces have more than one scar type, we build the plan around your particular mix.
At a Glance
- A meta-analysis of 37 studies found the pooled prevalence of acne scars among acne patients is approximately 47%[5]
- Atrophic (depressed) scars account for approximately 80-90% of acne scars, with ice pick, boxcar, and rolling subtypes[4]
- Risk factors for acne scarring include acne severity, delayed treatment, family history, and male gender[5]
- Modern acne scar treatment typically uses a multi-modal approach combining several techniques for different scar types[3]
Signs & symptoms
- Depressed or pitted areas in the skin (atrophic scars)
- Small, deep, narrow depressions resembling puncture marks (ice pick scars)
- Broad, rectangular depressions with well-defined edges (boxcar scars)
- Shallow, wide depressions giving skin a wavy or undulating appearance (rolling scars)
- Raised, firm areas of excess scar tissue (hypertrophic scars)
- Uneven skin texture or roughness in areas of prior acne
- Discoloration or pigmentation changes at scar sites
What causes Acne Scarring
- Severe inflammatory acne (cystic or nodular acne)
- Disruption of the dermis during the acne healing process
- Insufficient collagen production during wound repair (atrophic scars)
- Excessive collagen production during wound repair (hypertrophic or keloid scars)
- Picking, squeezing, or manipulating acne lesions
- Delayed or inadequate treatment of inflammatory acne
Risk factors
- Severe or cystic acne
- Family history of acne scarring
- Delayed treatment of inflammatory acne
- Male gender
- Repeated or relapsing acne episodes
- Picking or squeezing acne lesions
- Darker skin tones (higher risk of post-inflammatory changes)
- Smoking
How it's assessed
- Visual examination of the affected skin
- Classification of scar types (ice pick, boxcar, rolling, hypertrophic)
- Assessment of scar depth and severity
- Evaluation of active acne that may need treatment first
- Review of prior acne history and treatments
- Assessment of skin type and tone for treatment planning

Recovery & outlook
- Most acne scars can be significantly improved with appropriate treatment
- Combination treatments typically produce better outcomes than single modalities
- Multiple treatment sessions are often needed over several months
- Complete elimination of deep scars may not be possible, but substantial improvement is typical
- Treating active acne first is essential to prevent new scarring
- Results depend on scar type, depth, skin type, and treatment approach
Frequently Asked Questions
- Acne scarring is a permanent change in skin texture caused when inflammatory acne damages the deeper layer of skin. If healing produces too little collagen, depressed scars form; if it produces too much, raised scars can develop. The most common scars are the atrophic types: ice pick, boxcar, and rolling scars.
- Ice pick scars look like small, deep, narrow pits. Boxcar scars are broader depressions with well-defined edges, while rolling scars create a shallow, wavy, or uneven surface. Hypertrophic scars appear as raised, firm areas of scar tissue. Many people have several scar types at once, particularly on the cheeks, temples, and forehead.
- Acne scars form when inflammatory acne damages the dermis, the deeper layer of skin. During healing, too little collagen creates depressed scars and too much collagen creates raised scars. Severe acne, delayed treatment, and picking or squeezing acne lesions can increase the risk of scarring.
- See a dermatologist if acne scars affect your confidence or quality of life, if active acne is not responding to over-the-counter treatments, or if you want to explore professional treatment options. A clinical evaluation can identify the scar types present and guide a personalized treatment plan.
- Treatment is typically tailored to the scar types present and combines several methods. Options include laser resurfacing, microneedling, subcision for tethered scars, dermal fillers for volume loss, and chemical peels for texture improvement. Multiple sessions over several months are typically needed for optimal results.
- Most acne scars can be significantly improved, although complete removal of deep scars may not always be possible. Modern multimodal treatment can substantially reduce their appearance over a series of sessions. Results depend on the scar type and depth, skin type, and treatment approach.
- The most effective way to prevent acne scars is to treat inflammatory acne early and effectively. Avoid picking, squeezing, or otherwise manipulating acne lesions, since this increases the risk of scarring. Sunscreen on healing acne helps prevent post-inflammatory hyperpigmentation. If over-the-counter treatments are not controlling the acne, seek professional care promptly.
- Acne scarring describes several different shapes of damage. A rolling scar is normal-thickness skin pulled downward by fibrous strands beneath it, so it responds to subcision that cuts those tethers and to methods that add volume underneath. A boxcar scar is a crater with defined shoulders, and resurfacing lowers the surrounding skin toward its base. An ice pick scar is a narrow tract that runs deep into the dermis. A laser strong enough to reach its bottom would damage everything around it, so ice pick scars are excised or treated with a focused acid technique. At Aesthetx, we write the plan by naming the particular scars present and matching a method to each.
- Active inflammation should be controlled first. Resurfacing skin that is still breaking out risks new scars in the healing tissue. Pigment left by recent lesions often fades on its own over six to twelve months, so treating too early can mean spending money on marks that were going to resolve anyway. Distinguishing residual discoloration from true textural scarring is done by touch as much as sight: a flat mark is pigment, while a contour change is a scar. This requires a dermatologic assessment. We offer dermatology and surgical scar revision within the same practice, so we can care for either finding here.
