Thank you for your question and for sharing your photograph. The profile view reveals two distinct contributing factors to the contour you are concerned about. The first is laxity in the skin beneath the chin, and the second is a secondary contour created by volume deep to the platysma muscle. It is worth noting that this deeper volume is largely hereditary in nature, rather than being driven by lifestyle or the aging process. A deep contouring neck lift is well suited to address both of these elements comprehensively. In terms of the deeper structures, the procedure can reduce volume contributed by deep-seated fatty tissue, the digastric muscles, and the lower portion of the submandibular glands. At the same time, it addresses the skin laxity along the jawline and beneath the chin, producing a smoother, more defined, and better-proportioned neck profile.
