Age 18, & want a heart shaped face, what will slim my lower cheek? (Photos)

You are a good candidate for a genioplasty. Your chin considered short and slightly recessed. By bringing it forward and slightly down, we could create a more "v" shaped chin and jawline, while fixing the asymmetry at the same time. In doing so, this will also lengthen your jawline and add more definition. If needed, we can contour the chin and jawline after to get the perfect shape you are looking for. Our office can make simulated photos of expected outcomes. We are happy to set up a virtual or in-person consultation if you would like to discuss things further!
