Microneedling has become one of the most heavily marketed acne scar treatments online. Social media often presents it as a simple solution for acne scars, enlarged pores, and uneven skin texture. However, many patients spend thousands of dollars on repeated microneedling sessions only to see minimal improvement in deeper acne scars.
The reason is simple: most significant acne scars are not just surface-level texture problems.
At the Scar Healing Institute, we frequently see patients who have undergone years of microneedling with little improvement in rolling or tethered acne scars because the underlying structural issue was never addressed.
Why Many Acne Scars and Keloid Scars Do Not Respond Well to Microneedling
Many depressed acne scars are physically tethered beneath the skin by fibrotic scar bands. Acne scars form when inflammation damages the pore, the surrounding tissue, and nearby sebaceous glands. The severity of inflammation often determines how deep the scar becomes. About 80% of people between the ages of 11 and 30 experience acne, and one in five develops scarring.
Atrophic acne scars are the most common type of depressed acne scar, while hypertrophic or keloid scars are raised because excessive collagen is produced during healing, and include:
- Rolling scars
- Boxcar scars
- Ice pick scars
In rolling scars especially, fibrotic bands pull the skin downward, creating shadows, indentations, and uneven texture.
Microneedling does not release these tethered scar attachments.
Instead, microneedling creates controlled superficial micro-injuries that stimulate collagen production. While this may improve mild texture irregularities or pore appearance, it often produces disappointing results for moderate-to-severe atrophic acne scars.
Patients commonly notice:
- Mild smoothing of the skin
- Temporary swelling that briefly makes scars appear improved
- Minimal lifting of deeper scars
- Persistent depressions despite multiple treatments
This is particularly common with rolling acne scars and tethered boxcar scars.
What Microneedling Actually Improves
Microneedling may help improve:
- Mild skin texture irregularities
- Enlarged pores
- Fine lines and certain wrinkles
- Superficial acne scars
- Overall skin quality
However, marketing often exaggerates its ability to treat severe acne scarring.
Patients with moderate or severe acne scars frequently undergo 6–10 microneedling sessions without meaningful correction because, in that treatment process, collagen stimulation alone cannot overcome deep scar tethering.
Why Subcision Often Produces More Noticeable Improvement
Subcision is a minor surgical procedure, also known as subcutaneous incisional surgery, designed to treat depressed scars by releasing the fibrotic bands tethering the skin downward.
During subcision, a specialized hypodermic needle or cannula is inserted through a small puncture in the skin surface beneath the skin to break the fibrotic strands tethering the scar to the underlying tissue. Once the tethering is released, the skin can elevate more naturally, and collagen remodeling can occur beneath the scar. This technique is typically performed in an outpatient setting and is generally well tolerated.
Subcision may be performed at different tissue depths depending on scar severity:
- Superficial-layer subcision
- Mid-layer subcision
- Deep-layer subcision
For deeper tethered scars, more advanced instruments may be used to target dense fibrotic scar tissue more effectively. It also carries a low risk of post-inflammatory hyperpigmentation, making it safe for all skin types.
The Hazany Liberator
Since the development of the Taylor Liberator, subcision techniques and instrumentation within dermatology have continued to evolve. One of the latest advancements is the Hazany Liberator, a proprietary, patented device exclusively available at the Scar Healing Institute.
In our experience, this advanced instrument has demonstrated improved outcomes for atrophic rolling and boxcar acne scars as a cosmetic scar-revision tool while offering a shorter recovery time compared to traditional subcision tools. The procedure is performed in-office under local anesthesia and is generally well-tolerated with minimal downtime. Common short-term side effects include bruising, swelling, tenderness, and minor soreness at the treatment site. Serious complications are uncommon but can include infection, hematomas, and scar recurrence.
How Subcision Improves Acne Scars and Scar Tissue
Once scar attachments are released:
- The skin can elevate more naturally
- Scar depth may visibly improve
- Collagen remodeling occurs beneath the scar as new collagen fibers form under the treated area
- Long-term structural improvement becomes possible
This is why subcision is often considered one of the most effective treatments for rolling acne scars. Improvement comes from both releasing the tethering and stimulating new collagen formation during wound healing, which can help the skin heal more smoothly and create a smoother-looking surface.
The Problem With “Collagen Stimulation” Marketing
Many acne scar treatments are marketed around the idea of “boosting collagen.” While collagen stimulation is important, collagen alone does not fix mechanically tethered scars.
A scar that is physically anchored downward often requires the release of the deeper fibrotic attachments. In contrast, surface treatments such as chemical peels can smooth texture but do not undo that deeper anchoring.
This is why some patients undergo years of:
- Microneedling
- RF microneedling
- PRP microneedling
- Fractional laser resurfacing
…yet continue to see persistent depressions in the same areas. Surface-focused treatments may improve texture, but they often fail to release deeper structural tethering, so patients may not reach desired results when that deeper tethering is left untreated.
Why RF Microneedling Is Not the Same as Subcision
Radiofrequency (RF) microneedling is often marketed as a more advanced alternative to traditional microneedling for acne scars and other skin conditions. While RF microneedling can create deeper thermal injury and stimulate collagen more aggressively, it still may not adequately release deep scar tethering.
For many patients with rolling acne scars, RF microneedling alone still falls short because the scar’s structural attachments remain intact.
RF microneedling and subcision are separate procedures with different goals, and a qualified healthcare provider should choose the appropriate technique based on scar type and severity:
- RF microneedling focuses primarily on collagen stimulation
- Subcision focuses on releasing tethered scar tissue
Many patients ultimately benefit from combining both treatments as part of a comprehensive acne scar revision plan.
Can Microneedling Delay Effective Acne Scar Treatment?
In some cases, yes.
Many patients repeatedly pursue minimally invasive treatments because they are marketed as having low downtime and being universally effective. Unfortunately, this can delay more appropriate structural acne scar treatments such as:
- Subcision
- CROSS
- Laser resurfacing
- Biostimulatory fillers such as Sculptra
- Combination acne scar revision procedures
By the time patients seek advanced scar revision, they may have already spent years pursuing treatments that were poorly matched to their scar type.
Is Microneedling Ever Worth It? Considering Side Effects
Microneedling is not useless. It can still be a helpful treatment for:
- Mild textural irregularities
- Maintenance treatments
- Minimal acne scarring
- Texture refinement after structural scar correction
However, patients with moderate-to-severe rolling acne scars should understand that microneedling alone is often insufficient.
Why Combination Acne Scar Treatment Often Works Best
Acne scarring is complex, and most patients have multiple scar types at the same time.
An effective acne scar treatment plan often combines:
- Subcision for rolling and tethered scars
- CROSS for ice pick scars
- Laser resurfacing for texture and pigment
- Biostimulators such as Sculptra for volume loss
- Microneedling as a secondary texture-refining treatment
It may also help selected scars from chickenpox or previous surgery, as well as certain wrinkles or cellulite, and the scar’s location on the body can affect treatment planning.
The key is addressing the underlying scar architecture rather than relying only on surface collagen stimulation.
FAQ: Subcision vs. Microneedling
Why do my acne scars still look the same after microneedling?
Many acne scars are tethered beneath the skin by fibrotic scar tissue. Microneedling does not release these attachments, so some depressions remain obvious even after repeated sessions because the tethered areas are still attached beneath the skin.
Is subcision better than microneedling for rolling scars?
In most cases, yes. Subcision directly targets the tethering responsible for rolling acne scars, making it one of the most effective treatments for this scar type.
Can microneedling permanently remove acne scars?
Microneedling may modestly improve superficial acne scars, but it rarely fully corrects deeper atrophic acne scars on its own. Not all acne marks are permanent, and some may continue to improve as the skin continues to heal over time.
Why is microneedling so heavily marketed?
Microneedling is widely available, relatively easy to perform, and associated with minimal downtime, making it highly marketable. However, marketing does not always reflect the most effective treatment for severe acne scarring.
Does RF microneedling replace subcision?
Usually not. RF microneedling may improve texture and collagen production closer to the epidermis, but it often does not adequately release deep scar tethering. It may help some superficial texture concerns, but subcision is still needed when deeper scar bands remain tethered in the dermis.
Can subcision and microneedling be combined?
Yes. Many acne scar specialists combine subcision with microneedling, laser resurfacing, fillers, or other treatments, depending on scar type and severity. A dermatologist may combine these differently based on the scar pattern and overall severity.
Final Thoughts
Microneedling is often overpromised as a solution for acne scars. It is not designed for raised hypertrophic scarring, including hypertrophic and keloid scars, which may show redness and feel itchy or painful and usually need different management. While it may improve mild textural irregularities, it frequently fails to significantly improve deeper rolling or tethered acne scars because it does not address the underlying structural problem.
For patients with moderate or severe atrophic acne scarring, subcision is often one of the most important treatments because it targets the scar tethering beneath the surface rather than relying only on superficial collagen stimulation. Some patients also ask about related cosmetic concerns such as burn scars or other visible scars that makeup can only partially conceal.
The most effective acne scar treatment plans are individualized and often combine multiple procedures to address scar depth, texture, tethering, and volume loss comprehensively. Acne scars often develop in areas with active sebaceous glands, while other scar types may need silicone therapy, corticosteroid injections, or excision rather than subcision, and vitamin products are not primary treatment for structural scars.
