BodyTite vs Renuvion: How They Work, FDA Status and Safety Evidence
BodyTite uses bipolar radiofrequency during liposuction; Renuvion uses helium plasma. How they compare on mechanism, FDA clearance, FDA warnings, study results and complications. No prices or winner.
BodyTite and Renuvion are both used under the skin, usually alongside liposuction, to try to tighten loose skin. The short answer: BodyTite heats tissue with bipolar radiofrequency (RF), while Renuvion uses helium plasma plus RF. Evidence for both comes mostly from surgeon-reported case series, and Renuvion has a notable FDA safety history that's worth understanding before you choose.

Side-by-side
| Feature | BodyTite (InMode) | Renuvion (Apyx Medical) |
|---|---|---|
| Energy | Bipolar RF through an internal probe and external electrode (Theodorou et al., Aesthetic Plast Surg, 2012) | Helium plasma with RF energy (FDA) |
| Typical use | During liposuction of the abdomen, arms, thighs and other areas | Under the skin, often after liposuction |
| FDA status for aesthetic tightening | Varies by indication; ask your surgeon which clearance covers your procedure | One handpiece cleared in July 2022 for loose skin of the neck and under the chin (FDA 510(k) K220970) |
| FDA warnings | None specific found | March 2022 safety communication (see below) (FDA) |
How BodyTite works
BodyTite is a radiofrequency-assisted liposuction (RFAL) device. RF energy melts fat, controls bleeding and heats tissue to cause contraction. In an early series of 97 patients treated under local anesthesia, the rate of major complications was 6.25% (Theodorou et al., Aesthetic Plast Surg, 2012).

How Renuvion works
Renuvion delivers helium plasma with RF energy under the skin, coagulating tissue. The FDA describes the device as cleared for cutting, coagulation and ablation of soft tissue during surgery (FDA).
Renuvion's FDA history
- March 2022: the FDA warned against using Renuvion/J-Plasma for skin resurfacing or skin contraction, alone or with liposuction, after reports of serious and potentially life-threatening events, including second- and third-degree burns, infection, scars, nerve damage, significant bleeding and gas collecting under the skin, in body cavities and in blood vessels (FDA).
- July 2022: the FDA cleared the Renuvion APR handpiece for subcutaneous procedures to improve loose skin in the neck and under the chin (FDA 510(k) K220970). That clearance doesn't cover other body areas or use with liposuction.
What the studies show
| Study | Findings |
|---|---|
| Kluska et al., 2024, single-center retrospective review (229 Renuvion, 236 BodyTite patients) | Fewer adverse events with Renuvion (45 events in 34 patients) than BodyTite (93 events in 62 patients), including fewer burns, hematomas, raised scars and seromas (Kluska et al., Plast Reconstr Surg Glob Open, 2024) |
| Swanson, 2025, systematic review of 25 Renuvion publications | No standardized measured photos comparing Renuvion with traditional methods; most studies manufacturer-funded; FDA reports included 15 life-threatening events and 3 deaths; helium-related lung and chest complications in case reports; concluded no evidence of tightening beyond liposuction alone (Swanson, Ann Plast Surg, 2025) |
The two papers reach very different conclusions, which shows how limited and contested the evidence is.
Questions to ask your surgeon
- What is the device cleared for, and is my use on-label?
- How many of these procedures have you done, and what complications have you seen?
- What results can you show with standardized photos?
- Would surgery, such as a tummy tuck or arm lift, give a better result for my amount of loose skin?
What neither replaces
Significant loose skin, such as after major weight loss, usually needs surgical removal. Energy devices are aimed at mild to moderate laxity.
Recovery
Both are done with liposuction in most cases, so recovery resembles liposuction: swelling, bruising and compression garments. Report blistering, spreading redness, shortness of breath or chest pain immediately.
Frequently asked questions
Is Renuvion FDA-approved? One handpiece is cleared for loose skin in the neck and under the chin. The FDA warned against other aesthetic uses in 2022.
Is BodyTite safer than Renuvion? Studies conflict, so we can't say. Your surgeon's experience matters a lot.
Can these replace a tummy tuck? Not for significant loose skin.
