I've been looking into ultherapy & have a question about frequency. Ultherapy is ultrasound energy that focuses deep beneath the skin and stimulates collagen production via the body's own regenerative response to the treatment. Hypothetically, although the ultherapy effects continue through 2-3 months after the fact, what would stop someone from having ultherapy once a week for instance? Negligible results/Cost inaffectiveness? Redness/soreness goes quick so wouldn't it be okay to go again soon?
