Neck lift or liposuction? (Photo)

Based on the photos, I believe neck liposuction might not be the most beneficial option for you. This procedure typically targets fat tissue located below the skin and above the muscle, and you appear to have a naturally thin layer of fat under your neck skin.
A neck lift is usually performed to address signs of aging, such as marionette lines, sagging cheeks, platysmal bands, or a “turkey neck” appearance. However, these signs are not evident in your photos.
What I observe is a well-defined jawline at the front, but this sharp contour doesn’t extend towards your earlobes. To enhance your profile, I suggest considering jawline fillers to elongate your jawline and create a more pronounced gonial angle. This might help improve the appearance of your neck’s cervicomental angle without the need for surgery.
I recommend starting with jawline fillers before exploring surgical options.
