Las Vegas – At the fall edition of The Cosmetic Bootcamp (CBC), Susan Van Dyke, M.D., discussed similarities and differences between various radiofrequency (RF)-based treatments for fat and cellulite. She is a Paradise Valley, Arizona-based dermatologist.
RF treatments attempt to deliver heat energy into fat to melt it, using contact or noncontact devices, she said. “But I believe the way that RF works is more in the dermis and in skin tightening. There’s fat and there’s laxity in the skin quality. Radiofrequency is very helpful with both conditions.” Monopolar RF penetrates more deeply than bipolar and tripolar RF, she added.
Microneedling procedures such as ThermiTight deliver heat through an array of tiny needles. Rather than true fat reduction, said Dr. Van Dyke, these treatments provide mainly tightening and reduction in the appearance of cellulite to make patients’ skin look younger.
Treatments that combine fat reduction with cellulite improvement involve modalities such as low-level light and massage, she said. Because these treatments do not kill fat cells, she said, results are temporary. “They can be a good adjunct to some of the more permanent or long-lasting procedures.”
