Sculptra for jawline? (Photo)

Thank you for your photos. Sculptra could be used for your jawline but ideally I recommend it for larger areas where you desire a significant amount of added volume such as sunken cheeks. Unlike other injectable fillers, Sculptra is a volumizing filler that causes the body to produce new collagen. This means it takes longer to show results, but also that the results may last longer than other filler. I recommend getting an in-person consultation with a board-certified dermatologist.  

So I would need a lateral to say for sure but I think you have a strong chin. You can of course always make it stronger but for you, i think it is more likely that you are experiencing the early signs of mid and lower facial ageing. Rather than strengthening your chin, there may be something more surgical that you might want to consider like a neck lift. Hope that helps, Adam Goodwin
