Dr. Z: Another Imperative Innovation

Following his success with body sculpting, Dr. Z’s attention shifting to another common cosmetic surgery procedure in need of a touch-up: liposuction.

He spent countless hours reading up on the evolution of the procedure and evaluating different techniques. In the end, he felt that the liposuction methods at the time just weren’t taking advantage of the innovations that were out there. So, in true Dr. Z fashion, he invented his own: TickleLipo.

Dr. Z Innovates Ticklelipo

Dr. Tim Zelko’s TickleLipo treatment revolutionized the industry by reducing the size of incisions and by only having to utilize local anesthesia.

Through these advancements, Dr. Z is able to improve results and recovery times for his patients with this minimally invasive procedure.
