RAP device being investigated as a way to improve appearance of cellulite



Soliton’s Rapid Acoustic Pulse (RAP) device, which was cleared for tattoo removal in 2019, is being investigated as an option to improve the appearance of cellulite.

“The procedure is relatively painless, without anesthesia and can easily be delegated with physician oversight,” Mathew M. Avram, MD, JD, said during the virtual annual Masters of Aesthetics Symposium. “Side effects have been minimal and transient to date. There is no down time.”

According to Dr. Avram, director of laser, cosmetics, and dermatologic surgery at Massachusetts General Hospital, Boston, the RAP device emits rapid acoustic pulses (shock waves) that are transmitted through the skin to rupture or “shear” the fibrotic septa. This causes the release of septa, which results in a smoothening of skin dimples.

“Basically, what you have is a repetition rate and very short rise time that provide microscopic mechanical disruption to the targeted cellular level structures and vacuoles,” Dr. Avram explained. “There’s a high leak pressure and fast repetition rate that exploits the viscoelastic nature of the tissue. You get compressed pulses from electronic filtering and the reflector shape eliminates cavitation, heat, and pain.”

The procedure takes 20-30 minutes to perform and it generates minimal heat and pain, “which is an advantage of the treatment,” he said. “It is completely noninvasive, with no incision whatsoever. No anesthetic is required. There can be physician oversight of delivery, so it is delegable, and there is no recovery time. More study is needed, and we need to stay tuned.”

Dr. Avram disclosed that he has received consulting fees from Allergan, Merz, Sciton, and Soliton. He also reported having ownership and/or shareholder interest in Cytrellis.
