Is Ultherapy safe?

Safety is the first question many people ask before treatment. If you are in Mamaroneck, Larchmont or nearby, start with what the Cleveland Clinic reports about its clearance.
The direct answer
The Cleveland Clinic's Ultherapy page says the FDA "cleared the procedure after it demonstrated its safety in clinical studies."
Two points matter there: the agency cleared the procedure, and the clearance followed clinical studies that demonstrated its safety.

Published research gives more detail on ultrasound and similar treatments. One paper reviews energy-based devices for facial skin conditions in skin of color, and a retrospective study of patient satisfaction follows people treated with micro-focused ultrasound with visualization. A systematic review combining microfocused ultrasound with visualization and calcium hydroxylapatite looks at the two treatments together. All three are listed in PubMed Central (NIH).
What you can do now
Ask the clinic who performs the treatment and how they handle questions afterwards. Tell them about your skin type and any other treatments you have had, such as Radiesse or Sculptra.
What to leave alone
Do not decide on your own that a symptom after treatment is normal. Do not book a second session to fix something you are unsure about without speaking to the clinic first.
If something after treatment worries you, call the clinic that treated you.
The question that comes next
People often ask how Ultherapy fits with injectables such as Botox or dermal fillers. Bring both lists of treatments to your consultation.
