Napa, Calif. – Not only does combining fillers and microfocused ultrasound (MFUS) not weaken fillers, attendees learned at the fall Cosmetic Bootcamp (CBC), but the combination also may enhance results.
Heating hyaluronic acid (HA) to 65°C does not change it, said Paradise Valley, Arizona-based dermatologist Susan Van Dyke, M.D. Fillers are routinely sterilized at much higher temperatures, she noted. “There are now studies that show that it does not impact the effectiveness of HA.”
A 2007 study showed that laser, radiofrequency and intense pulsed light treatments performed immediately after HA injections did not impact the injections’ effectiveness. A preclinical trial showed similar results, and that the combination enhanced collagen deposition. “That’s very exciting, and that study was published 13 years ago. We’ve known that something about this combination is synergistic.”
