What Can I Do to Firm Up my Jaw Line Without a Face Lift?

A physical examination by an experienced board certified plastic surgeon is the best way to determine the most suitable treatment, however you may want to look into injectable fillers, like Juvederm. Fillers can recontour your jawline with a simple injection treatment. Results last for several months to over a year, depending on your physiology. Another option is laser skin tightening, which can stimulate the production of collagen and elastin to firm up the skin along your jawline. This may require several sessions to achieve your goals, but it is worth a try if the treatment is suitable for you.

By firming up I assume you mean a stronger more visible jawline. Unless you a lot of loose skin a facelift alone will not do this. In some cases liposuction just under the jawline can create a slight concavity that makes the jawline more prominent. This obviously does not work in every patient. The only other options are jaw surgery, jaw implants and to some degree injectable fillers.
