Micro-focused Ultrasound Safe for Darker Skin Types


A study by JAMA Facial Plastic Surgery designated micro-focused ultrasound (MFU) a safe treatment to tighten and lift skin on the face and neck of darker skin types.

Testing MFU’s Safety for Improvement

MFU with ultrasound visualization is a system developed to treat lax, aging skin. Previous trials have proven the system to be a safe and efficient non-invasive esthetic treatment.

A non-randomized trail in 52 patients—35 black and 51 being women—was performed to demonstrate the safety of MFU for improving laxity of the skin in adults with darker skin types, specifically Fitzpatrick skin types III to VI.

The trial was performed by Monte O. Harris, M.D., Center for Aesthetic Modernism, Chevy Chase, M.D.; and Hema A. Sundaram, M.D., Dermatology, Cosmetic & Laser Surgery in Rockville, Maryland and Fairfax, Virginia.

Outcome in Adverse Events

After 90 days without complications, the authors reported the treatment resulted in:


The study concluded patients with Fitzpatrick skin types III to VI can safely utilize MFU when performed by trained physicians.

"The proven safety of microfocused ultrasound in patients with Fitzpatrick skin types III to VI adds another instrument to the armamentarium of nonablative facial rejuvenation for surgeons who treat patients with all skin types,” said Oneida Arosarena, M.D., Temple University, Philadelphia. “Further studies are needed to determine the efficacy of this therapy in patients of color."
