First, congratulations on the weight loss. A robust HA filler injected appropriately to the upper outer cheek region would help to provide cheek projection and volume and create a more oval, heart-shaped face. Likewise, a robust HA filler injected appropriately in the region of the posterior angle of the mandible would help to straighten and define the jawline, lessening the jowl formation there and even to some extent improving the upper neck region immediately below below. A less robust, more cohesive HA filler fanned through the region immediately around the mouth would help to lessen the crepeyness and parallel laugh lines that are visible in the profile photo. And finally, an even lighter HA skin booster could be injected in the next region to diminish the cords and crepeyness there. Be wary of the claims you will no doubt encounter for the purported benefits of relatively expensive fraxel lasers, RF or ultrasound devices. Unfortunately, the hard science to date to support these claims lags woefully behind the advertising and media hype that promotes them. Make sure to consult with a board certified cosmetic dermatologist and ask to see his/her personal before and after photos before agreeing to proceed. Best of luck.
