Weight loss can make the face look tired because it may reduce facial volume and reveal loose skin or mild descent in the cheeks, jawline, and neck. The best treatment depends on whether the main issue is volume loss, skin laxity, or true tissue descent, and that can only be judged accurately with an in-person exam. If the face is mainly deflated, options such as fat grafting or carefully placed filler may help restore support and soften a tired look. If there is significant jowling, cheek descent, or neck laxity, a facelift or neck lift may give a more meaningful and durable lift than nonsurgical treatments. Skin treatments can improve texture, but they do not lift loose tissue very much. A consultation with a board-certified plastic surgeon who can examine your skin quality, facial volume, and neck/jawline laxity would help you choose between volume restoration, nonsurgical tightening, and surgical lifting.
