Natural Growth Factors are either injected or microneedled with SkinPen for the treatment of scarring from injuries, stretch marks, and surgery. Growth Factors can dramatically reduce the scars from breast augmentation, tummy tuck, or knee replacement surgery. Typically, 3 to 4 treatments are needed for optimal results. Be sure to arrive 15 minutes early so we can numb you. Before your Scar treatment begins, we will draw your blood, so please be sure to stay hydrated before your appointment by drinking plenty of water.
