Dr. Thieu is very knowledgeable. She really took her time listening to me and my concerns. She explained the process and what to expect. I started to notice a difference in movement and the smoothing begin after about the 4th or 5th day after my procedure. I has now been 2 weeks and I am seeing the full effects. I do not know how or why I didn't do this earlier. I love my results! Smooth sailing ( my forehead literally) from now on.
