Understanding Rolling Acne Scars vs. Box Scars
Rolling Acne Scars: The Wave-Like Depressions
Rolling acne scars develop when fibrous bands of tissue form beneath the skin’s surface, creating characteristic wave-like or rolling depressions across the affected area. Key characteristics include:
- Wave-like appearance with soft edges
- Result from tissue tethering beneath skin
Box Scars: The Sharp-Edged Depressions
Box scars present as round or oval-shaped depressions with steep, well-defined vertical edges. These scars create a distinctive appearance with several defining features:
- Round depressions with sharp borders
- Commonly found on cheeks and jawline

Why Multiple Scar Types Often Coexist
It’s important to understand that many individuals develop a combination of different scar types, especially when acne has reached moderate to severe levels.
After significant breakouts, you may notice rolling scars alongside box scars, ice pick scars, or areas of post-inflammatory hyperpigmentation. This mixed scarring pattern requires a comprehensive treatment approach that addresses each scar type appropriately.
Professional Treatment Options for Acne Scars
Most Effective Treatments for Rolling and Box Scars
- Subcision – Breaks up fibrous bands
- Fractional CO2 Laser – Deep resurfacing treatment
- Dermal Fillers – Add volume beneath scars

Subcision: The Foundation Treatment
Subcision represents one of the most effective treatments for rolling acne scars and certain types of box scars.
This minor surgical procedure involves inserting a specialized needle beneath the skin to break up the fibrous bands that cause the tethering effect in rolling scars.
During subcision, the practitioner carefully maneuvers the needle to release the scar tissue while avoiding damage to surrounding healthy tissue.
This process allows the depressed areas to rise closer to the level of surrounding skin. The procedure can be enhanced with the addition of collagen stimulators or combined with other treatments for optimal results.
Recovery from subcision typically requires several days, with some bruising and swelling expected.
Treatment sessions should be spaced at least three to four weeks apart to allow proper healing between procedures.

Fractional CO2 Laser Therapy
Fractional CO2 lasers offer powerful resurfacing capabilities for treating deeper acne scars. This technology removes microscopic columns of skin tissue in a fractionated pattern, promoting healing and collagen regeneration in the treated areas.
The advantage of fractional CO2 lasers lies in their ability to penetrate deeper than many other laser types while generating controlled heat that stimulates robust collagen synthesis. This makes them particularly effective for treating box scars and deeper rolling scars.
However, fractional CO2 laser treatment carries a higher risk of side effects, including post-inflammatory hyperpigmentation, particularly in individuals with darker skin tones. A thorough evaluation by an experienced practitioner is essential before proceeding with this treatment option.

Dermal Filler Treatments
Dermal fillers provide an immediate improvement in the appearance of certain acne scars by adding volume beneath the depressed areas.
This treatment works particularly well for rolling scars and shallow box scars, where the primary issue is volume loss rather than severe textural irregularities.
Common filler materials used for acne scar treatment include hyaluronic acid-based products, calcium hydroxylapatite, and specialized acne scar fillers.
The results are visible immediately after treatment, though the effects are temporary, typically lasting nine months to one year.
The success of filler treatment depends heavily on proper injection technique and thorough understanding of facial anatomy.
Complications such as lump formation can occur if the procedure is not performed by an experienced injector.

Chemical Peeling Procedures
Chemical peels work by removing damaged outer layers of skin, promoting the growth of new, healthier skin underneath. Different depths of chemical peels address various types of acne scarring.
Superficial peels using alpha-hydroxy acids or beta-hydroxy acids can improve mild textural irregularities and post-inflammatory hyperpigmentation.
Medium-depth peels incorporating trichloroacetic acid can address more significant scarring, while deep peels using phenol are reserved for severe cases.
TCA CROSS (Trichloroacetic Acid Chemical Reconstruction of Skin Scars) represents a specialized chemical peeling technique specifically designed for treating individual acne scars.
This procedure involves applying high-concentration trichloroacetic acid directly to specific scars, causing controlled damage that stimulates collagen production and new skin growth.

Microneedling and Radiofrequency Microneedling
Microneedling treatments use fine needles to create controlled micro-injuries in the skin, triggering the body’s natural healing response and promoting collagen production. This treatment can be effective for mild to moderate atrophic acne scars.
Radiofrequency microneedling combines traditional microneedling with radiofrequency energy delivery, providing enhanced results through deeper tissue heating.
This combination therapy can address rolling scars, box scars, and ice pick scars more effectively than microneedling alone.
The treatment can be uncomfortable, often requiring topical anesthesia or other pain management methods. Multiple sessions are typically necessary to achieve optimal results.

Surgical Interventions
For severe or isolated acne scars, surgical treatments may provide the best outcomes. These procedures are typically reserved for cases where less invasive treatments have proven insufficient.
Punch excision involves surgically removing individual scars and closing the resulting wound with sutures. This technique works well for deep, well-defined box scars and ice pick scars.
Punch grafting removes the scarred tissue and replaces it with a skin graft, typically harvested from behind the ear. This approach can be effective for larger or deeper scars.
Surgical subcision, while related to the needle subcision described earlier, involves making larger incisions to release extensive scar tissue. This procedure may be combined with other treatments for comprehensive scar revision.
Treatment Combinations and Protocols
The Multi-Modal Approach
Effective acne scar treatment often requires combining multiple therapies to address different aspects of scarring.
A typical treatment plan might begin with subcision to release tethered tissue, followed by fractional laser therapy to improve overall skin texture, and conclude with filler treatments to address remaining volume deficits.
Treatment Scheduling and Recovery
Proper spacing between treatments is crucial for optimal results and safety. Most practitioners recommend intervals of at least four weeks between intensive procedures, though some treatments can be performed more frequently.
The total treatment timeline may extend over several months or even years, depending on the severity of scarring and the selected treatment approach.
At-Home Treatment Options
Topical Treatments for Mild Scarring
- Retinoids – Promote collagen production
- Chemical exfoliants – Improve skin texture
Factors Affecting Treatment Success
Key Success Factors
- Skin type – Affects treatment selection
- Practitioner experience – Critical for best results
Practitioner Experience
The skill and experience of the treating practitioner significantly impact treatment safety and effectiveness. Procedures like subcision, laser therapy, and chemical peels require specialized training and experience for optimal results.
Managing Expectations and Realistic Outcomes
Understanding Treatment Goals
Complete elimination of acne scars is rarely achievable, and realistic expectations focus on significant improvement rather than perfection. Most patients can expect 50-80% improvement in scar appearance with appropriate treatment.
Timeline for Results
Results from acne scar treatments develop gradually over months. Initial improvements may be visible within weeks, but final results often take six months or longer to fully manifest as collagen remodeling continues.
Special Considerations and Contraindications
Isotretinoin Interactions
Patients taking isotretinoin (Accutane) should avoid certain treatments, particularly fractional laser therapy, as this medication can impair healing and increase scarring risk. A waiting period of at least six months after discontinuing isotretinoin is typically recommended before proceeding with intensive scar treatments.
Skin Type Considerations
Different skin types respond differently to various treatments. Darker skin tones may be at higher risk for hyperpigmentation with certain procedures, requiring modified treatment approaches and careful post-treatment care.
Active Acne Management
Active acne should be well-controlled before beginning scar treatment procedures. Ongoing inflammatory acne can interfere with healing and potentially create new scarring.
Cost Considerations and Treatment Planning
Treatment Investment
Acne scar treatments represent a significant financial investment, with costs varying widely based on treatment type, geographic location, and practitioner expertise. Most insurance plans do not cover cosmetic scar treatments.
Treatment Prioritization
When budget constraints exist, prioritizing treatments based on scar severity and treatment effectiveness can help maximize results. Starting with the most proven treatments for your specific scar types provides the best value.
Prevention and Maintenance
Preventing Future Scarring
- Never pick acne lesions – Most important prevention step
- Use daily sunscreen – Protects from UV damage
Post-Treatment Maintenance
- Sun protection – Use SPF 30+ daily
- Follow-up appointments – Monitor progress
When to Seek Professional Consultation
Evaluation Timeline
Anyone considering acne scar treatment should consult with a board-certified dermatologist or plastic surgeon experienced in scar revision. Early consultation can help develop an appropriate treatment plan and set realistic expectations.
Red Flag Symptoms
Seek immediate medical attention if treated areas show signs of infection, including increased warmth, pus formation, or red streaking. Unusual pain or changes in scar appearance should also prompt professional evaluation.
Frequently Asked Questions
How long does it take to see results from acne scar treatments?
