KYBELLA® (deoxycholic acid) injection is the first and only FDA-approved injectable treatment that contours and improves the appearance of submental fullness, sometimes referred to as “double chin”. The active ingredient in KYBELLA is deoxycholic acid, a naturally-occurring molecule in the body that aids in the breakdown and absorption of dietary fat. When injected into the fat beneath your chin, KYBELLA causes the destruction of fat cells. Once destroyed, those cells cannot store or accumulate fat. The procedure includes two treatments, typically 6-8 weeks apart, with very little downtime.
