There are two phases of correction after Ultherapy. The first is collagen contracture, which literally is occurring as we perform the procedure. As a result, many patients will appreciate a subtle, but distinct, improvement in their appearance within a few days following the treatment. Ultimately the more impressive correction is from collagen stimulation. Your body responds to the pinpoint thermal injuries placed in the deep tissue by creating new collagen fibers. Collagen fiber formation can take several months, so the final results from Ultherapy may take up to 6 months.
