Is 600 shots sufficient to improve overall facial elasticity, or should I receive 900 shots for guaranteed effectiveness?
The number of shots does not necessarily mean that more is better; it is important to decide based on the facial area, degree of sagging, and desired improvement range. If the goal is partial elasticity improvement, 600 shots are often sufficient, while if you are concerned about overall contour, you might consider 900 shots. The exact number of shots should be designed individually through a skin diagnosis for safety.
