Dr. Matthew White is one of the developers of the Ulthera ultrasound technology now being used to erase wrinkles.
"We're actually able to focus on the smas layer," he explains. "The smas layer is the precise layer that as surgeons we usually pull tighter when we perform a surgical face lift."
It's the muscle layer under the skin.
"Once we image with ultrasound it tells us precisely where the energy is going to be deposited, so we treat the deeper smas layer, cause it to lift and tighten," Dr. White says. "Then in the same setting we actually go back and treat the deep skin dermis...so you get a two level treatment that really helps to lift and tighten the facial tissues."
It's also believed the ultrasound's low level heat triggers the wound healing process and stimulates collagen growth over time, firming up skin.
"The really neat thing about it is, that improvement continues to get better and better as time passes," says Dr. White.
The treatment takes about 90 minutes and cost varies, but should be around $1,500.
