Thank you for your question. At 37, a neck that is beginning to look thinner, more gaunt, or “bony” does not necessarily need a neck lift. In fact, when the concern is loss of softness and volume rather than excess lax skin or fullness, removing additional tissue could potentially accentuate the problem. The youthful neck is influenced by several layers: skin quality and thickness, subcutaneous fat, the platysma and deeper neck structures, and the underlying skeletal anatomy. Genetics, natural aging, and changes in weight or body composition can all affect how prominently these structures are visible. Based on the photograph alone, the changes seem very mild. I would recommend seeking a consultation with a plastic surgeon who specializes in face and neck rejuvenation to better understand your concerns and try to determine exactly which layer is creating the appearance that bothers you. Depending on the findings, treatment might focus on improving skin quality and collagen using minimally-invasive techniques, carefully restoring soft-tissue volume when appropriate, or simply observation (no intervention at all) if the anatomy is normal and the changes are subtle. I would be particularly cautious about aggressive liposuction or surgical neck contouring in someone whose primary complaint is already that the neck appears too thin or gaunt. An in-person examination would allow assessment of your skin, soft-tissue volume, platysma, deeper neck anatomy, and facial proportions. At your age, the goal should be a conservative, individualized approach that sets you up for long-term success, and restores a healthy, natural appearance without over-treating the neck.
