The mentalis muscle is primarily responsible for the movement of the lower lip and the chin area. One of its key functions is to wrinkle the chin, which occurs when the muscle contracts. This action can be observed when a person is expressing emotions such as doubt or displeasure. By creating folds in the skin of the chin, the mentalis contributes to the overall facial expressions, making it a significant muscle in the dynamics of facial movements. Understanding the function of the mentalis muscle is important for estheticians as it helps them grasp how facial expressions can impact a client's appearance and treatment approach.
