Chin filler volume and shape to escape a receding chin and complete a sharp profile.

When viewed from the side, I have a typical receding chin face shape with my lower jaw deeply set inward. Because my chin tip is short and blunt, my mouth appears much more protruding in comparison. Furthermore, even a slight weight gain causes the fat under my chin to overlap, creating a double chin appearance, which has always been a complex for me due to my unsophisticated impression. I cannot bring myself to undergo facial contouring surgery due to the recovery period and potential side effects, so I would like to create a sophisticated V-line profile by slightly shortening the length of my chin and adding volume through a Maypure chin filler procedure. I am curious to know approximately how many cc of filler is required to achieve a natural and sharp chin shape. I would also like to know if pain or discomfort in the jaw persists for a long time immediately after the procedure when chewing food or eating hard foods.
