Ulthera and People with Muscle Athrophy?

Ulthera shouldn't cause any muscle atrophy, since the focused ultrasound produces such a discrete injury at 0.5 mm and 0.9 mm in size.  The muscle layers are not targeted, so I find very little risk of this.  I hope this helps!

Ulthera works by stimulating fibroblasts produce collagen. There is no evidence that Ulthera will stimulate new muscle growth.
