Cyrolipolysis + Subcision for Cellulite
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to evaluate the effectiveness of two treatments for cellulite on the outer thighs. One treatment uses cryolipolysis, which cools fat to break it down. The other combines cryolipolysis with surgical subcision, a procedure that cuts the fibrous bands under the skin. Women with noticeable cellulite on their outer thighs, visible when standing or lying down, may be suitable candidates for this study. Participants will assist researchers in determining which treatment more effectively reduces cellulite. As an unphased trial, this study offers participants the chance to contribute to innovative research that could lead to new cellulite treatments.
Will I have to stop taking my current medications?
If you are currently taking antiplatelet or anticoagulant medications, you will need to stop as they are not allowed in this trial. For other medications, the protocol does not specify, so it's best to discuss with the trial team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that cryolipolysis, a treatment that reduces fat by freezing it, is generally safe. Studies indicate a low rate of side effects, with only about 2% of treatment sessions resulting in mild and treatable negative effects. Most people who have tried cryolipolysis report high satisfaction with the results, and it is safe for all skin types.
Less specific safety information exists about combining cryolipolysis with subcision, a minor procedure that cuts fibrous bands under the skin. However, cryolipolysis alone is well-tolerated, and subcision has been safely used in other treatments. This suggests the combination might also be safe, though combining treatments could introduce new risks. It is important to consult healthcare providers to understand the potential benefits and risks before deciding to join a trial.12345Why are researchers excited about this trial's treatments?
Researchers are excited about combining cryolipolysis and subcision for cellulite because this approach targets the problem in two innovative ways. Cryolipolysis is a non-invasive treatment that freezes fat cells, helping to smooth out the skin's surface. Subcision, on the other hand, involves using a needle to break up the fibrous bands beneath the skin that contribute to the dimpled appearance. Unlike standard treatments like topical creams or laser therapy, this dual approach addresses both fat reduction and the structural causes of cellulite, potentially offering more comprehensive and longer-lasting results.
What evidence suggests that this trial's treatments could be effective for cellulite?
Research has shown that cryolipolysis, a treatment that freezes fat cells to reduce fat, yields promising results. One study found that patients experienced an average fat reduction of 28.5% in treated areas. Cryolipolysis can also improve skin texture and reduce the appearance of cellulite. In this trial, some participants will receive cryolipolysis alone, while others will receive a combination of cryolipolysis and subcision, a simple procedure that breaks up bands under the skin. Although specific data on combining both treatments isn't detailed here, the combination is believed to target cellulite more effectively by enhancing both fat reduction and skin texture.14678

Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants receive either cryolipolysis or a combination of cryolipolysis and surgical subcision on the outer thighs
Follow-up
Participants are monitored for changes in cellulite severity using a live rating by a blinded dermatologist
What Are the Treatments Tested in This Trial?
Interventions
- Cryolipolysis
- Subcision
Trial Overview
The study is testing if cryolipolysis alone or combined with surgical subcision is more effective for treating cellulite. Each participant's one thigh gets cryolipolysis and the other thigh also gets subcision. A dermatologist will rate cellulite severity before treatment and after three months without knowing which thigh received which treatment.
