Changes in facial expression after Botox treatment must be evaluated based on muscle movements.

Botox works by affecting signal transmission between nerves and muscles.

Therefore, the movement of facial muscles may vary depending on the treatment area and dosage.

Rather than just checking the depth of wrinkles, you should also examine the muscles used when making facial expressions.

It is recommended to evaluate areas that influence each other, such as the forehead and the space between the eyebrows, together.

Uniform procedures that do not take individual muscle movements into account can lower satisfaction.

You must consider both maintaining a natural facial expression and the goal of improvement together.
