Alternative Procedure to Tighten Jawline?

Thank you for the question.  Certainly one of the earlier signs of age is the loss of sharpness of the jawline contour.  I never think age should be the main component in deciding the treatment options.  It really is more about the clinical situation, patient’s desire on the final result, and the patient’s situation in regards to recovery time and financial comfort.  In our practice, we offer the list of options from least aggressive to most aggressive emphasizing that more aggressive usually is synonymous with more result and longevity.  The list is too long to go through here.  I certainly think that the first line of treatment to consider are various skin tightening machines such as Ultherapy and Thermage, knowing there is a limit to their effectiveness.  There are now more minimally than invasive technologies such as micro needling with RF, Precision lift using laser assisted liposuctionmg, and subdermal RF such as Facetite.  They all have pros and cons.  The next level up from this are surgical options such as limited lower facelift  to full facelift.  It is very important to discuss these options with an experienced board certified plastic surgeon.  I think it’s important that the practice have all these options available so a truly accurate recommendations and expectations can be discussed.

For early skin laxity then there are a number of skin-tightening lasers such as Thermage, SkinTyte and Ultraformer III that improve skin laxity with minimal or no down-time. These however need to be continued for ongoing improvement.The use of dermal fillers can also disguise the presence of early jowls by smoothing out the contour along the jawline.For more advanced skin laxity then surgery - lower facelift and necklift is the best option, giving you a long-lasting result

Surgery is not for everyone. In today's day and age, there are many surgical and nonsurgical options to address various concerns one has for their face as they age.
In general, surgery is one of the best ways to address jowls. However, skin tightening and all sorts of injectables can definitely help significantly especially for patients that are not interested in surgery. If you're ever interested in surgery, the procedure is much different than what you're probably reading about online. A short scar facelift that addresses the jowls & marionette lines can typically be done under local anesthesia in the office, usually in as little as 20 to 30 minutes. There are usually no drains, recovery is quick and most patients take no narcotics.
I would recommend that you see a board-certified plastic surgeon in your area that is a member of both ASPS & ASAPS and performs a lot of facelifts but also offers all the nonsurgical options such as injectables and laser treatments. Go over your concerns with them and make sure above all, you walk out of there with several options and never be pushed out with just one suggestion. Ultimately there are pros and cons to every procedure whether it's surgery or not surgery. It should always be your choice. I have had 80 year old patients be very happy without having had any surgical procedures.
I hope this helps and wish you all the best in your surgery and event. If it does, please take a moment to up vote this answer on the “respond” button on the top right.
