Two trendy, noninvasive cosmetic surgery treatments now available in Hawaii promise no cutting, no scarring, no side effects and no downtime.

One — Ultherapy — relies on the same ultrasound imaging technology used to examine pregnant women or treat kidney stones to reduce the appearance of saggy cheeks, jowls, jawlines and necks. The other — Coolsculpting — is touted as a less traumatic option to liposuction to remove unwanted bulges.

“The baby boomers are driving this market. They don’t want to let aging come without a fight,” said Dr. Todd Mirzai of Hawaii Plastic Surgery Associates, who began offering Ultherapy early this year.

Both treatments have been approved by the Food and Drug Administration.
