Can Rolling Acne Scars Be Removed?
A Specialist’s Honest Guide
You've tried the creams. You've done the microneedling sessions at a beauty salon. You've had the chemical peels. And yet the shadows are still there, those rolling, wave-like indentations that catch the light in the wrong way and make you feel like your skin will never look smooth again. There's a reason those treatments haven't worked and it's not you. It's the biology of rolling acne scars, and once you understand it, the path forward becomes much clearer.
At Eve Clinics, we treat acne scarring every week using a combination protocol, view our scar removal treatment page that addresses the underlying cause rather than just the surface. In this guide, we'll explain exactly what rolling acne scars are, why they behave differently to other scar types and what the evidence actually says about the best treatment options available in the UK in 2026.
What Are Rolling Acne Scars, and Why Are They Different?
Not all acne scars are the same. The three main types, rolling, boxcar and ice-pick, have different structures beneath the skin, which is why they respond differently to treatment. Rolling scars are arguably the most misunderstood and most undertreated of the three.
Rolling scars form when fibrous bands of scar tissue develop beneath the skin, anchoring the surface skin down to the deeper tissue layers. These bands physically tether the skin, pulling it inward and creating the characteristic undulating, wave-like depressions that shift and move when you stretch the skin sideways. This is the key distinguishing feature of a rolling scar, and it is also the key to understanding why most standard treatments fail.
Creams, serums and surface-level treatments cannot reach these fibrous bands. They sit below the dermis, often extending into the fat layer beneath. No amount of retinol, vitamin C or even standard microneedling will break them down. The tether remains and the shadow remains with it.
| Scar Type | Appearance | Cause | Why Surface Treatments Fail | Best Treatment |
|---|---|---|---|---|
| Rolling Scars | Broad, wave-like, shallow-to-medium depth. Surface moves when skin is stretched sideways. | Fibrous bands tethering skin to subcutaneous tissue beneath. | The band sits below the dermis, topicals and surface lasers cannot reach it. | Subcision to release the band + CO2 laser to remodel collagen above. |
| Boxcar Scars | Round or oval depressions with sharply defined, vertical edges. Shallow to deep. | Collagen destruction leaving a flat-bottomed pit with steep walls. | The defined walls need remodelling, not just stimulation. | CO2 laser resurfacing, plus punch excision for deeper variants. |
| Ice-Pick Scars | Narrow, deep, V-shaped channels extending into the dermis. Like a pin-hole. | Severe follicular inflammation creating a narrow tract of destruction. | Too narrow and too deep to be remodelled by laser or needling alone. | TCA CROSS chemical reconstruction, punch excision, followed by laser resurfacing. |
In clinical practice, the majority of acne scar patients present with a combination of rolling, boxcar and occasionally ice-pick scars. The treatment approach needs to address each type individually within the same protocol, which is why a thorough consultation and scar mapping is essential before any treatment begins.
Why Most Treatments Don't Work for Rolling Scars
This is the question we hear most from new patients: "I've already spent thousands on treatments that didn't do much, why would this be different?" It's a fair question and it deserves an honest answer.
The majority of treatments marketed for acne scarring, salon microneedling, medium-depth chemical peels, LED therapy, high-street laser facials, work at the level of the epidermis and upper dermis. They stimulate some collagen remodelling and improve skin texture and tone. For mild surface scarring, they can be genuinely helpful.
But rolling scars are not a surface problem. The fibrous bands that create them sit in the deep dermis and subcutaneous layer, well below where these treatments reach. Stimulating collagen above the tether without releasing the tether itself is a bit like redecorating a ceiling while the floor beneath is still pulling it down. You might see a slight improvement, but the fundamental problem remains.
The two interventions that actually address the underlying structure are subcision (which physically releases the fibrous band) and ablative CO2 laser resurfacing (which remodels the collagen architecture above). Used in combination, they address the problem from both directions simultaneously, and the evidence consistently shows that combination protocols produce significantly better outcomes than either treatment alone.
The Eve Clinics Approach: Subcision + CO2 Laser
Our combination protocol for rolling acne scars is built around two core interventions, sequenced and calibrated individually for each patient. We do not operate from a set menu of sessions, the protocol is designed around your specific scar type, depth, distribution, skin tone and history.
Step 1: Subcision: Releasing the Tether
Subcision is a minor surgical procedure performed under local anaesthetic. A fine needle or cannula is inserted beneath the skin at the base of each scar and moved in a sweeping fan motion to physically cut through the fibrous bands anchoring the scar to the tissue below. Once the band is released, the surface skin is free to rise, and the body's natural wound-healing response floods the area with new collagen to fill the space left behind.
Subcision alone can produce meaningful improvement in rolling scars, but the collagen produced in the healing response tends to be irregular and insufficient to fully correct deeper depressions. This is where CO2 laser becomes critical.
Step 2: CO2 Laser Resurfacing: Remodelling From Above
Following subcision, we use the DEKA SmartXide CO2 laser to treat the skin surface. The laser creates precise microscopic columns of controlled thermal injury, triggering a structured collagen remodelling cascade in the dermis. This new collagen fills, firms and smooths the scar depression from above while the subcision has released it from below. The combination is significantly more powerful than either treatment alone because it addresses the scar's structure at both levels simultaneously.
In patients with particularly deep rolling scars, we may also incorporate RF microneedling (Morpheus8) into the protocol as an intermediate step, adding radiofrequency-driven collagen stimulation in the mid-dermis to bridge the gap between subcision depth and laser surface depth.
How Many Sessions Will I Need?
This varies significantly between patients and is something we discuss in detail during your consultation. As a general guide:
- Mild rolling scarring: 1–2 sessions of subcision + CO2 laser, spaced 3–4 months apart
- Moderate rolling scarring: 2–3 sessions, spaced 3–4 months apart, potentially with RF microneedling intermediate sessions
- Severe or longstanding rolling scarring: 3–4 sessions over 12–18 months, with a sequenced multi-modality protocol
We always space sessions a minimum of 3 months apart to allow the collagen remodelling triggered by each treatment to mature fully before reassessing. Treating too frequently interrupts the healing process and reduces the cumulative benefit.
CO2 laser and subcision combination treatment achieves visible, meaningful improvement in rolling acne scars in the vast majority of patients. A realistic expectation is 50–80% improvement over a full course of treatment. We do not promise complete elimination, no ethical clinician should. What we do promise is a thorough assessment, an honest protocol and direct access to our clinical team at every stage.
Rolling Acne Scars vs. Other Scar Treatments: What the Evidence Says
| Treatment | Reaches Fibrous Band? | Collagen Remodelling | Best Evidence For | Downtime |
|---|---|---|---|---|
| Subcision + CO2 Laser | Yes, releases band + resurfaces | Deep + surface, dual layer | Rolling scars, mixed scarring | 7–12 days |
| CO2 Laser Alone | No, surface remodelling only | Strong, upper-to-mid dermis | Boxcar, surface texture, mixed mild | 7–10 days |
| RF Microneedling (Morpheus8) | No | Good, mid dermis via RF heat | Mild-moderate rolling, skin tightening | 3–5 days |
| Salon Microneedling | No | Moderate, upper dermis only | Mild surface texture, skin tone | 1–3 days |
| Chemical Peels | No | Moderate, epidermis/upper dermis | Pigmentation, mild surface texture | 5–7 days |
| Topical Retinoids | No | Mild, surface cell turnover only | Post-inflammatory pigmentation, maintenance | None |
What to Expect: Recovery After Subcision and CO2 Laser
Because our acne scar protocol combines two procedures, recovery is slightly longer than CO2 laser alone, though not dramatically so for most patients.
Immediately After Treatment
The subcision sites will feel bruised and tender and you will likely experience some swelling, particularly in the first 24–48 hours. The CO2 laser component means the skin will also be red and hot, similar to a significant sunburn. Both of these are normal and expected responses.
Days 1–3
Swelling and bruising from the subcision peaks in this window. The skin will begin to bronze as the surface healing process begins. Plan to be at home during this period. Apply your prescribed aftercare balm as directed and avoid touching or examining the skin too closely, the urge to assess progress at this stage is understandable, but the appearance at day 2 is no indication of the final result.
Days 4–7
Bruising fades. The surface skin will begin to peel as the laser-treated layer sheds. The swelling from subcision will have significantly reduced and you may begin to see early lifting of the scar depressions, though this is often partially masked by the residual surface healing. Most patients are comfortable with remote working from day 5 with camera off.
Days 7–10
Surface healing is complete for most patients. The fresh skin underneath is smooth and noticeably refined in texture. There will be a pink or rosy flush to the skin that mineral makeup can cover comfortably. Most patients are socially presentable by day 8–10 and comfortable returning to work in person.
Months 1–6
This is where the real results develop. The collagen remodelling triggered by the laser, combined with the new collagen generated by the body to fill the subcision space, matures progressively over three to six months. Most patients notice the most significant visible improvement between month two and month four. We schedule a review appointment at this stage to assess progress and plan any further sessions if needed.
Fresh post-treatment skin is significantly more vulnerable to UV-induced hyperpigmentation, particularly relevant for acne scar patients, many of whom already have some degree of post-inflammatory pigmentation alongside their scars. SPF 50 every morning, every day, for a minimum of three months post-treatment is not optional. It is the single most important thing you can do to protect your results.
Is This Treatment Right for My Skin Tone?
This is a question we take seriously. Darker skin tones (Fitzpatrick IV–VI) carry a higher risk of post-inflammatory hyperpigmentation (PIH) with ablative laser treatments, meaning the treatment itself can sometimes worsen pigmentation if not performed with care and expertise.
At Eve Clinics, we do not take a one-size-fits-all approach. For patients with Fitzpatrick IV–VI skin, we:
- Perform a thorough skin tone assessment at consultation, including Fitzpatrick typing and PIH risk evaluation
- Adjust the DEKA SmartXide laser settings, reducing density and energy to minimise thermal spread while maintaining clinical efficacy
- May recommend a pre-treatment conditioning protocol (typically a topical tyrosinase inhibitor for 4–6 weeks before treatment) to reduce PIH risk
- Start conservatively and build gradually across sessions, reviewing response at each stage
We will always be honest with you if we feel the risk profile for your skin tone makes ablative laser inadvisable. In some cases, RF microneedling alone or in combination with subcision is a safer and still highly effective alternative. The right answer for your skin is the one we discuss together at consultation, not a decision made before we've seen you.
Adult Acne Scarring: It's Never Too Late
A significant proportion of the patients we treat for rolling acne scars have carried them since their teens or twenties, sometimes for decades. A common concern is whether scars that have been present for many years are still treatable or whether the window for improvement has passed.
The answer is reassuring: mature acne scars respond well to combination treatment. The fibrous bands that cause rolling scars remain present and accessible regardless of how long the scar has been there. Subcision can release them effectively whether they formed five years ago or thirty. The collagen remodelling response triggered by CO2 laser is also not age-dependent in any clinically significant way, patients in their 40s and 50s respond just as well as patients in their 20s in our experience.
If anything, patients who have been living with their scars for years and finally decide to pursue treatment tend to be among the most motivated and satisfied, because they know better than anyone what a meaningful improvement looks like for their skin.
