Rolling scars sits at the center of this dementia and brain health question.
Rolling scars are depressions in the skin caused by fibrous bands of scar tissue beneath the surface that create a rolling, undulating appearance—typically measuring 4-5 millimeters wide—and they can be temporarily smoothed if you stretch the skin. They develop most commonly as a result of severe inflammatory acne, particularly cystic acne, where the skin’s healing process becomes disrupted and the body produces insufficient collagen to fill the damaged area. If you’ve experienced moderate to severe acne and notice wave-like dips across your skin that give it a rippled texture, you’re likely dealing with rolling scars.
This article explains what causes these scars to form, why they’re different from other types of acne scars, and walks through the treatment options available—from minimally invasive procedures to newer combination therapies that are showing promise in recent research. Rolling scars represent one of the most common forms of atrophic scarring, affecting 15-25% of all patients with atrophic acne scars. What makes them distinct is their appearance: rather than appearing as sharp, pinpoint marks like icepick scars, they create a gentle but noticeable depression with sloped sides, making the entire affected area look uneven and aged. The good news is that treatments have evolved significantly, with several evidence-based options ranging from subcision (a surgical technique that releases the fibrous bands) to newer approaches combining regenerative medicine techniques.

What Causes Rolling Scars and Why Acne Leads to Scarring
Rolling scars form when the body’s wound-healing response goes awry after severe acne inflammation. When deep cystic acne lesions develop, they damage the collagen and elastin fibers in the deeper layers of skin. During the healing process, the body attempts to repair this damage by producing new collagen, but in cases of rolling scars, the collagen production is unregulated and insufficient—the fibrous bands that form beneath the skin tether the surface downward, creating that characteristic rolling or rippled appearance.
The severity and extent of scarring depends heavily on the acne’s intensity and how long it went untreated. Approximately 95% of patients with acne disease may develop some degree of scarring, though severity varies considerably. Someone who had mild comedonal acne and treated it promptly might experience no lasting scars, while someone who dealt with cystic acne for years before seeking treatment may develop extensive rolling scars. The delay in treatment is particularly critical: the longer inflammatory acne persists, the more damage accumulates in the dermal layers, and the harder the body’s healing process has to work to compensate.
Understanding Rolling Scars Versus Other Types of Acne Scarring
Rolling scars are just one category of atrophic (depressed) acne scars. The other main types are icepick scars, which are narrow, deep, and pinpoint-like, and boxcar scars, which are wider with more defined edges and vertical walls. A single person with severe acne history might actually have a combination of all three types. Rolling scars tend to look the most “subtle” at first glance—they blend into the skin with their gentle slopes—but because they affect larger surface areas, they can actually make the skin appear more globally uneven and aged than the more dramatic but smaller icepick or boxcar marks.
However, if you have rolling scars, this distinction matters for treatment selection. Subcision, for example, works particularly well for rolling scars because it specifically targets the fibrous bands anchoring the scar. Procedures designed for icepick scars might not be as effective for rolling scars. Additionally, rolling scars can sometimes improve slightly with time—not disappear entirely, but become less noticeable—whereas icepick scars typically remain stable or worsen. This natural improvement happens as the body gradually reorganizes collagen and as skin loses some elasticity with age (though this isn’t really an advantage, since it’s coincidental).
The Role of Collagen Disruption in Rolling Scar Formation
At the microscopic level, rolling scars exist because of how collagen fibers arrange themselves after the injury heals. In normal skin healing, collagen fibers organize in a relatively random, three-dimensional mesh that provides flexibility and resilience. In rolling scar formation, collagen fibers become organized in a way that creates tension and shortening of the skin. Think of it like a fabric that’s been pulled and sewn in a way that permanently puckers—the fabric itself is intact, but it no longer lies flat.
The specific trigger for this abnormal collagen organization remains an active area of dermatological research. What we know is that excessive inflammation during the acne lesion’s lifetime sets the stage for problematic healing. If the cystic acne is particularly deep or if multiple lesions cluster together, the damage extends through multiple dermal layers, and the body’s repair mechanisms become overwhelmed. The distinction is important: mild acne doesn’t typically produce enough depth of damage to cause rolling scars, which is why people with persistent but superficial acne often don’t scar significantly.
Subcision as a Primary Treatment for Rolling Scars
Subcision is one of the most effective treatments specifically for rolling scars because it directly addresses the underlying cause—the fibrous bands anchoring the skin downward. During subcision, a dermatologist uses a special needle inserted beneath the scarred skin to deliberately sever these fibrous bands. Once released, the skin can rise back to a more normal level, and the body’s natural healing response is triggered, which prompts new collagen formation in the area.
The procedure is minimally invasive but requires skill and precision. A single subcision session typically improves rolling scars by 25-50%, though some sources report even better results when combined with other treatments. The downside is that you’ll have bruising and swelling for 1-2 weeks, and you might need multiple sessions spaced several weeks apart to achieve optimal results. Additionally, subcision alone doesn’t always produce dramatic improvement if the scar is very severe or if there’s significant skin laxity (loose or sagging skin), which is why combination approaches are becoming more popular.
Microneedling and Laser Therapy for Collagen Remodeling
Microneedling, also called collagen induction therapy, works through a completely different mechanism than subcision. Fine needles create controlled micro-injuries across the scarred skin, triggering the body’s natural wound-healing cascade and prompting new, healthy collagen production. For rolling scars, microneedling can gradually smooth the appearance by thickening the dermis (the deeper skin layer) and reducing the relative depth of the depression. Laser therapy—both ablative (removing the top layer of skin) and non-ablative (heating deeper layers without surface damage)—similarly aims to trigger collagen remodeling and skin resurfacing.
Fractional lasers are particularly useful because they treat only a fraction of the skin at a time, reducing downtime and allowing for multiple sessions. Chemical peels using medium-depth solutions like salicylic acid or Jessner’s solution also promote collagen remodeling. However, all three of these options (microneedling, laser, chemical peels) work more gradually than subcision and are less specifically targeted at the fibrous bands causing rolling scars. They tend to be better suited to superficial rolling scars or as complementary treatments combined with subcision.
Novel Combination Therapy with Regenerative Medicine
Recent developments in 2025 have introduced an exciting advancement: autologous fibroblast transplantation combined with platelet-rich plasma (PRP) injections. In this approach, fibroblasts (the cells responsible for producing collagen) are harvested from the patient’s own skin, cultivated in a lab, and then reintroduced into the scarred areas alongside PRP, which contains growth factors that enhance healing. Early results are significantly better than traditional single-modality treatments, with patients showing thicker and denser skin, larger reductions in scar volume, and finer pore size.
This approach is still relatively new and is not yet available at all dermatology practices, but it represents a shift toward regenerative medicine in scar treatment. The advantage is that it’s autologous (using the patient’s own cells), so there’s no risk of rejection, and it directly addresses the root problem—lack of healthy collagen—rather than just creating trauma to trigger the body’s natural response. The limitation is cost: regenerative treatments are typically more expensive than traditional options, and insurance coverage varies.
Prevention and Long-Term Management of Acne Scarring
The most effective approach to rolling scars is prevention, which means treating acne aggressively and early, before severe inflammation can damage the dermal layers. Anyone with moderate or severe acne should see a dermatologist rather than attempting home remedies or waiting for the acne to resolve on its own. Early intervention with prescription retinoids, oral antibiotics, hormonal therapies, or even isotretinoin (Accutane) for severe cases can prevent the inflammation that leads to scarring in the first place.
Once rolling scars have formed, they’re permanent without treatment, though they may appear less noticeable as skin naturally changes with age. The future of scar treatment is likely to increasingly involve regenerative approaches like the fibroblast transplantation techniques mentioned above, combined with traditional methods like subcision and microneedling. As these therapies become more refined and more widely available, the cosmetic outcomes for rolling scar patients will continue to improve.
Conclusion
Rolling scars are a common and challenging consequence of severe acne, caused by disrupted collagen production and fibrous bands of scar tissue beneath the skin’s surface. They affect 15-25% of patients with atrophic acne scars and are characterized by their distinctive rolling, undulating appearance. The good news is that multiple evidence-based treatments exist, from the highly targeted approach of subcision to the collagen-remodeling effects of microneedling and laser therapy, and emerging regenerative therapies are now showing even more promising results.
If you’re dealing with rolling scars, the best first step is consultation with a dermatologist who can assess the severity of your scarring and recommend a treatment plan tailored to your specific situation. In many cases, a combination of treatments yields better results than a single approach. And crucially, if you’re currently struggling with moderate to severe acne, protecting your skin from developing these scars in the first place through prompt, aggressive treatment is far easier than correcting them after the fact.
Frequently Asked Questions
Can rolling scars go away on their own?
No, rolling scars do not disappear without treatment. They may appear slightly less noticeable over time as skin naturally changes with age and loses elasticity, but this is not improvement in the scar itself—it’s just a shift in how the scar appears relative to surrounding skin. Treatment is required for actual improvement.
How many treatment sessions are typically needed?
This varies by treatment type and scar severity. Subcision often requires 2-4 sessions spaced 6-8 weeks apart. Microneedling and laser therapy typically need 4-6 sessions at 4-6 week intervals. Newer regenerative treatments may require only 1-2 sessions, though long-term outcomes are still being studied.
Can I use makeup or skincare to camouflage rolling scars while considering treatment?
Yes. Silicone-based primers and full-coverage foundations can temporarily smooth the appearance by filling in the depressions. Color-correcting concealers can also help neutralize any redness if the scars are recent. However, these are temporary cosmetic solutions and don’t address the underlying scar tissue.
Is combination therapy always necessary, or can a single treatment work?
Single treatments can be effective, particularly subcision for rolling scars specifically. However, combination approaches—such as subcision followed by microneedling or laser therapy—often produce better overall results, especially for extensive scarring. Your dermatologist can recommend the best approach for your individual situation.
Are there any side effects or risks with rolling scar treatments?
All treatments carry some risk. Subcision can cause bruising, infection, and in rare cases, nerve damage. Microneedling and lasers can cause temporary redness, swelling, and rarely, post-inflammatory hyperpigmentation. Regenerative treatments are newer, so long-term complication data is still being gathered, but early reports show good safety profiles.
