How Cellulite Forms and Why Subcision Works
Cellulite develops when fibrous connective tissue bands, called fibrous septae, run from the dermis into the subcutaneous fat layer and tether the skin. As fat lobules expand or skin thins with age, these bands pull the surface downward and create the familiar dimpling. This structural mechanism differs from overall body fat volume, which explains why liposuction does not reduce cellulite and can actually make dimpling more noticeable.
Subcision directly targets this mechanical cause by cutting or releasing the fibrous bands. Injectable enzymatic treatments such as QWO and mechanical subcision devices such as Aveli and Cellfina share this goal. They sever the tethering band, allow the skin to rebound, and soften the visible dimple. Each method differs in how it releases the band, how precisely it targets tissue, and what recovery and safety profile it carries.
Subcision-based procedures break the fibrous bands beneath the skin, and a multicenter study of 55 patients demonstrated improvement in the appearance of cellulite in 98% of treated patients at 2 years.1 Because subcision treats the structural cause rather than the surface alone, it remains the most evidence-supported cellulite treatment category in 2026.
QWO’s Development, Use, and Mechanism
QWO received FDA approval in July 2020 as the first injectable treatment for moderate-to-severe cellulite in the buttocks of adult women. Its active ingredient, collagenase clostridium histolyticum-aaes (CCH-aaes), is an enzyme derived from the bacterium Clostridium histolyticum. The same enzyme class had earlier approval as Xiaflex for Dupuytren’s contracture and Peyronie’s disease, where it dissolves collagen-rich fibrous tissue.
The QWO protocol used three treatment sessions spaced 21 days apart. At each session, a provider injected CCH-aaes into individual cellulite dimples, with up to 12 injections per session and up to 24 dimples treated in total. The enzyme broke down collagen-rich fibrous septae that tethered the skin, with the goal of a sustained release of the dimple over the weeks after each injection cycle.
The mechanism aligned with current science and the FDA approval generated strong clinical interest. However, the way QWO disrupted collagen in real-world tissue also contributed to extensive bruising and pigment changes, and the adverse event profile that appeared in pivotal trials ultimately led to its withdrawal from the market.
Why QWO Was Pulled From the Market
Bruising emerged as a very common adverse event in QWO clinical trials. Many patients experienced extensive bruising that covered large areas of the buttocks and lasted for weeks, far longer than most expected. A subset of patients also developed prolonged hyperpigmentation, or darkening of the skin at injection sites, that in some cases persisted for months after treatment ended.
This pattern of post-inflammatory hyperpigmentation raised particular concern for patients with medium to deeper skin tones, who already face higher discoloration risk after inflammation. The bruising and discoloration profile did not appear as a rare outlier. It showed up consistently in pivotal trial data and became more obvious as real-world use expanded beyond tightly controlled study groups.
Endo International announced the discontinuation of QWO in December 2022, citing commercial factors along with safety concerns. Regardless of the wording, QWO is no longer manufactured, distributed, or available for patient use in the United States. Providers who once offered QWO now rely on mechanical subcision options, and no similar injectable collagenase for cellulite has FDA approval as of mid-2026.
Evidence-Based Cellulite Treatments Available in 2026
The American Academy of Dermatology highlights several evidence-supported options for cellulite reduction, each with its own mechanism, session schedule, and durability. Subcision-based procedures have the strongest evidence, followed by certain laser treatments and acoustic wave therapy. Topical products, including those with 0.3% retinol or caffeine, show only modest benefit compared with device-based and procedural treatments.
Beyond subcision, several non-invasive modalities offer varying degrees of temporary improvement. Acoustic wave therapy is FDA-approved to help reduce the appearance of cellulite and uses high-frequency, low-intensity sound waves delivered through a handheld device. In one study, people with moderate or severe cellulite who received acoustic wave therapy reported satisfaction with results, although multiple sessions are required and results do not last permanently.1 Radiofrequency treatments follow a similar multi-session pattern. These devices heat tissue beneath the skin and, when combined with laser, suction, and massage in FDA-cleared systems, can produce a minor reduction in appearance, but results are short-lived and require ongoing sessions.1
Injectable approaches outside of subcision have also been explored. Carboxytherapy, which injects carbon dioxide gas beneath the skin, produces modest and temporary reduction supported by limited pilot data. Mechanical massage devices such as Endermologie require multiple 45-minute sessions, and one study of 10 women who received 8 treatments found only a small, short-lived reduction.
Among all available modalities, subcision-based procedures, including Aveli, Cellfina, and vacuum-assisted precise tissue release, show the most durable published outcomes and the clearest mechanistic rationale for structural cellulite. The following comparison outlines how leading one-time and multi-session options differ in sessions, downtime, and safety.
Comparison of Leading One-Time and Multi-Session Options
| Treatment | Number of Sessions | Typical Downtime | Key Safety Notes |
|---|---|---|---|
| Aveli (mechanical subcision) | 1 | Bruising and soreness resolving within 1–2 weeks | Requires pinch-test confirmation of structural cellulite, performed under local anesthesia, no serious adverse events reported in published use |
| Cellfina (needle subcision) | 1 | Soreness resolving in 1–2 weeks, bruising resolving by 4 weeks | No serious side effects reported, not suitable for non-structural cellulite |
| Cellulaze (laser subcision) | 1 | Swelling and bruising, return to normal activity within days to weeks | Minimally invasive, targets fibrous cords and thickens thinned skin, results reported to last a year or longer1 |
| Acoustic Wave Therapy | Multiple (typically 6–10) | Minimal, no incisions or anesthesia required | FDA-approved, noninvasive, results temporary and require maintenance sessions |
| Radiofrequency (device-based) | Multiple | Minimal | Results short-lived, requires ongoing sessions, often combined with other modalities |
Aveli Treatment: What Happens and How It Feels
Aveli is a handheld subcision device cleared to treat cellulite dimples on the buttocks and thighs. The procedure takes place in the office under local anesthesia. The provider inserts a small probe beneath the skin, uses a hook mechanism to identify and engage each fibrous septal band that causes a specific dimple, then severs that band with a single controlled motion. A real-time visual confirmation feature lets the provider verify band release before removing the device, which reduces the chance of incomplete treatment.
The one-session protocol offers a clear convenience advantage. Instead of returning for multiple visits over weeks or months, patients address all targeted dimples in a single appointment. Most patients notice bruising and soreness in the treated area for one to two weeks, yet they usually return to normal daily activity within a few days. Strenuous lower-body exercise typically pauses for about two weeks.
Aveli suits patients with structurally confirmed cellulite, meaning dimples deepen on the pinch test and show fibrous band tethering rather than skin laxity or fat distribution alone. It does not treat generalized skin texture, stretch marks, or volume loss, which may need complementary treatments. Long-term outcome data for Aveli continues to grow, and the mechanistic basis it shares with Cellfina, which showed 98% patient improvement at 2 years in a multicenter study, supports reasonable expectations for durable improvement in well-selected candidates.
Mirror Plastic Surgery’s Top-to-Bottom Cellulite Evaluation
Mirror Plastic Surgery starts cellulite care with a comprehensive consultation that can last up to one hour. Instead of entering the visit with a preset plan, the clinical team performs a structured top-to-bottom assessment that reviews anatomy, skin quality, dimple pattern, and whether cellulite is structural or non-structural. This distinction guides treatment, because subcision is indicated only for true structural cellulite confirmed via pinch test, and using it for non-structural cases would likely disappoint patients.
Non-surgical procedures at Mirror Plastic Surgery are led by Ellie Pranckevicius, FNP-BC, an Aesthetic Nurse Practitioner with ICU experience at Tampa General Hospital, 600 hours of advanced aesthetics training, and a Master’s in Nursing from the University of South Florida. Her background in both clinical nursing and esthetics supports a philosophy focused on education, anatomical precision, and honest expectations, including advising patients when a procedure can safely wait.
Mirror Plastic Surgery follows a safety-first, function-second, aesthetics-third hierarchy. Before recommending Aveli or any cellulite treatment, the team confirms that the patient’s anatomy supports the procedure, that expected benefits justify the recovery, and that no contraindications exist. The practice limits itself to one to two procedures per day so each patient receives full attention before, during, and after treatment, which contrasts with high-volume clinics that compress consultation time.
Who Aveli Helps, Recovery Timeline, and Maintaining Results
The ideal Aveli candidate is an adult with discrete cellulite dimples on the buttocks or thighs that deepen when the skin is pinched, confirming fibrous band tethering as the main cause. Candidates should be in stable health, at or near their goal weight, and understand that Aveli targets individual dimples. It does not change overall skin laxity, body contour, or fat volume.
Patients with non-structural cellulite, which appears as generalized texture changes, thin skin, or coarse fat distribution without clear tethered dimples, usually benefit more from other modalities. Treatments such as Morpheus8 microneedling radiofrequency may better match this pattern. The pinch-test step during consultation at Mirror Plastic Surgery helps ensure that Aveli is offered only when the anatomy supports it.
After Aveli, patients can expect bruising and tenderness in the treated area for one to two weeks. Sitting comfort often improves within the first week. Strenuous lower-body activity should pause for about two weeks. Visible improvement usually begins within a few days as swelling decreases, with continued refinement over the next three months as tissue remodels.1 Stable body weight and consistent skin care help maintain results, because large weight shifts can change the appearance of nearby untreated tissue.
Frequently Asked Questions
Why QWO Still Appears Online in 2026
QWO received extensive media coverage after its FDA approval in 2020 and was heavily promoted on clinic websites, social media, and beauty outlets. Much of that content remains indexed and searchable in 2026, which can make QWO seem current. In reality, Endo International discontinued QWO in December 2022, and no U.S. provider can legally administer it because production and distribution have stopped. Patients who see QWO mentioned online should treat that information as outdated and speak with a current provider about today’s options.
Differences Between Aveli and Cellfina
Aveli and Cellfina are both one-session, in-office subcision procedures that release fibrous bands beneath the skin to reduce cellulite dimpling. Their main technical difference lies in how they cut bands and confirm release. Aveli uses a hook-based probe with real-time visual confirmation so the provider can see that a specific band has been fully severed before removing the instrument. Cellfina uses a standardized needle-based subcision technique with vacuum stabilization to isolate and cut individual bands. Both use local anesthesia, share similar recovery timelines, and treat only structurally confirmed cellulite. The choice between them depends on provider training, patient anatomy, and the exact dimple pattern, which a thorough consultation will clarify.
Addressing Both Cellulite and Volume Without Surgery
Structural cellulite dimples and volume loss represent different anatomical issues and need different treatments. Aveli and Cellfina release tethered dimples but do not add volume or reshape the overall buttock. Volume concerns, such as flat projection, hip dips, or asymmetry, respond better to biostimulatory injectable treatments like Radiesse or alloClae, which stimulate collagen and add structural support. Some patients benefit from a combined plan that uses subcision for dimples and biostimulatory fillers for volume and contour. Ellie Pranckevicius at Mirror Plastic Surgery specializes in non-surgical BBL services and performs a full anatomical assessment to decide whether one or both approaches fit each patient.
Most Successful Cellulite Treatment Based on Current Evidence
Current evidence most consistently supports subcision-based procedures for patients with structurally confirmed cellulite. The multicenter study mentioned earlier, which showed 98% improvement at 2 years, supports subcision as the most reliable option for structural dimples.1 Acoustic wave therapy has shown patient satisfaction in a study of people with moderate or severe cellulite, although it requires multiple sessions and results remain temporary. Laser treatments such as Cellulaze have demonstrated results that can last a year or longer. No single treatment works best for everyone. Outcomes depend on accurate diagnosis of cellulite type, correct matching of treatment to anatomy, and provider expertise. The American Academy of Dermatology advises patients to consult a board-certified provider before any cellulite treatment, because results depend heavily on the skill and experience of the person performing the procedure.
Moving Forward After QWO: Choosing Next Steps
QWO is no longer available in the United States, and patients who see it referenced online are viewing outdated information. As noted earlier, the December 2022 discontinuation reflected market concerns about bruising and prolonged skin discoloration that affected a meaningful number of treated patients.
In 2026, the strongest evidence for durable cellulite reduction supports one-time subcision procedures. Aveli offers a single-session, anatomically targeted option for structurally confirmed cellulite dimples, with a recovery profile and durability supported by the same structural rationale that underlies Cellfina’s published data. For patients who also have volume concerns, biostimulatory injectable treatments can complement subcision as part of a comprehensive gluteal plan.
Mirror Plastic Surgery’s concierge model, built on an hour-long top-to-bottom assessment, anatomical precision, and a safety-first philosophy, ensures that every recommendation reflects the patient’s individual anatomy rather than a preset protocol. Ellie Pranckevicius, FNP-BC, brings ICU-level clinical judgment and advanced aesthetic training to each consultation.
