The photos show some submental fullness under the chin and softening along the jawline/neck angle. At age 31, a full facelift is not usually the first option unless there is true skin laxity from major weight loss, genetics, or prior procedures. What feels like the face is melting can come from several different things: excess fat under the chin, a small or recessed chin, early skin laxity, platysma muscle bands, or volume changes in the midface. The best treatment depends on which of those is dominant on an in-person exam. If the main issue is fat under the chin with good skin tone, submental liposuction or other neck-contouring options may help. If the chin is recessed, chin augmentation or filler can improve the jawline balance. If there is real loose skin or muscle banding, a limited lower face/neck lift may be discussed, but that is a bigger step and not automatically the right answer at your age. Skin-tightening treatments can help mild laxity, but they do not replace surgery when there is significant loose skin. A consultation with a board-certified facial plastic or plastic surgeon can sort out whether this is a fat, skin, muscle, or chin-proportion issue before choosing a procedure.
