The photos are limited, but they show mild softening along the jawline and a small amount of fullness under the chin rather than severe sagging. At 37, the best option depends on whether the issue is skin laxity, early jowling, fat under the chin, chin projection, or jawline definition. If the skin quality is good, non-surgical options such as carefully placed filler to the chin/jawline, neuromodulator to the neck bands, or energy-based skin tightening may make the area less noticeable. If there is true loose skin or early jowling, a mini-lift, lower facelift, or neck lift gives a more reliable change, but that may be more than you need. An in-person exam is needed to assess skin elasticity, bite/chin position, fat distribution, and whether a surgical or non-surgical plan fits your goals.
