Lines around the chin, often referred to as "marionette lines" or "pre-jowl sulcus," can be addressed through various treatments. For someone in their 20s with facial fat contributing to these lines, masseter Botox (Botulinum toxin) and buccal fat removal are potential options, but they target different areas and concerns. Treatment Options Masseter Botox (Botulinum toxin) Target Area: Masseter muscle. Effect: Reduces muscle mass and can slightly improve facial contours by decreasing the prominence of the masseter muscle, which might indirectly affect the appearance of the lower face. Duration: Temporary, lasting several months. Usefulness for Chin Lines: Limited direct impact on lines around the chin but can help with overall facial balance. Buccal Fat Removal Target Area: Buccal fat pads. Effect: Reduces cheek fullness, which can make the face appear slimmer and potentially improve the definition of the jawline and chin area. Duration: Permanent. Usefulness for Chin Lines: May help improve facial contours but does not directly address lines around the chin. Other Options Dermal Fillers: Can be used to fill in the pre-jowl sulcus or marionette lines directly, providing immediate results. Facial Contouring Procedures: Such as chin augmentation or facial liposuction, which can more directly address the shape and definition of the chin and jawline. It is crucial to consult with a qualified healthcare professional or plastic surgeon to determine the most appropriate treatment based on individual anatomy and aesthetic goals.
