lizethdez, I have no idea who Arian grande is but you could use a chin and perhaps a medial platysmaplasty. Do not do closed liposuction; not a good idea in the face or neck. See an experieinced specialsit with good photos and one the does "only faces". Search the Internet. Good luck!
A full set of photographs are required to make a determination about being a candidate for 2 surgical procedures. When patients have a weak and recessive chin profile, a chin implant can improve the projection of the chin which helps improve the jawline. Chin implants are manufactured in a large variety of sizes and shapes, are composed of Silastic, and are usually placed through a small incision underneath the chin. Liposuction of the fatty deposits in the neck can also help improve the jawline. Both a chin implant and liposuction of the neck are complementary procedures to each other to help with better jawline definition.
