Which muscle is commonly injected with botox to treat marionette lines?

The zygomatic major and minor muscles are the correct muscles to target when administering Botox to treat marionette lines. These lines form around the mouth and can give an appearance of sadness or frowning. The zygomatic major muscle is responsible for pulling the corners of the mouth upward, while the zygomatic minor assists in elevating the upper lip, contributing to facial expressions.

When Botox is injected into the zygomatic major and minor, it temporarily relaxes these muscles, reducing the movement that contributes to the indentation and sagging in the area, thereby smoothing out the marionette lines. This treatment enhances facial aesthetics by minimizing the appearance of these lines without significantly impairing other facial movements.

Other options, such as the masseter, orbicularis oculi, and frontalis muscles, serve different functions related to chewing, eye closure, and raising the eyebrows, respectively. While they can also be treated with Botox for other cosmetic purposes, they do not directly address the issue of marionette lines.
