Submental fullness may stem from inherited fat distribution, weight gain, or age-related skin laxity. Even individuals at a healthy weight can experience a double chin due to genetics or changes in collagen and fat with age. This creates a heavier, less sculpted appearance of the lower face and neck.

First-line care options include Kybella injections to target and permanently dissolve submental fat cells, pairing of Sculptra or Ariessence Pure PDGF+ to improve firmness, or CoolSculpting to noninvasively reduce fat under the chin.

Adults with moderate submental fat who want a more contoured jawline and profile without surgery.
