For enhancing marionette lines, which muscles are typically treated?

The treatment of marionette lines focuses on the muscles directly associated with the expression of the lower part of the face, particularly those that contribute to the formation of these lines around the mouth. The zygomaticus major and minor muscles are primarily responsible for elevating the corners of the mouth and play a significant role in facial expressions that can lead to the appearance of marionette lines when their function is weakened or affected by aging. The risorius muscle, which pulls the mouth's corners horizontally, also contributes to facial dynamics that influence the appearance of these lines.

By targeting these specific muscles, estheticians can help improve the overall aesthetic appearance by restoring a more youthful contour and reducing the depth of marionette lines. Treatments such as neuromodulators or other aesthetic interventions can enhance the function of these muscles, resulting in a better-defined facial structure and smoothing out the lines.

The other options are not typically associated with treating marionette lines. The masseter and temporalis muscles are involved in mastication and do not directly influence the area around the mouth. The buccinator muscle aids in the movement of food and does not primarily affect the appearance of marionette lines. The corrugator and frontalis muscles are related to
