Based on your photos, I believe that you will benefit from either fillers by an experienced injector or by a facelift. The photos that you submitted make it difficult to assess your cheeks since you are smiling, but I would recommend neurotoxins (muscle relaxants, such as botox, dysport or xeomin) to the forehead, between the eyes, and the crow's feet. I would further recommend fillers under the eyes, cheeks, smile lines, and lips. It's difficult to give you a chiseled jawline because of the significant laxity of the cheeks that blend into the neck. That would be the main limitation of fillers for your face. A facelift, coupled with fat grafting to the cheeks, smile lines, and lips, performed with an upper and lower eyelid lifts will give you the best possible result as it will address all the issues including loss of fat, laxity of jowls, and improving the jaw contour. As you know, surgery is more expensive, risky, painful, and requires downtime, but it can give you a long lasting result. Fillers are less expensive, less risky, less painful, and requires minimal downtime, but will give you a result that will last 1-2 years on the average. I recommend that you consult with a board-certified plastic surgeon who is skilled at both fillers and facelifts and let them advise you in person. Ultimately, you have to make the decision. The good news about having fillers in the near future is that if you don't like it, you can always have a facelift in the future.
