Kybella

A synthetic version of a bile acid is injected into the fat under your chin to permanently destroy those fat cells. FDA-approved, permanent fat reduction -- but each session causes significant swelling and bruising for 1-2 weeks, and nerve injury affecting the smile was documented in 4.3% of Phase 3 trial patients (though all resolved). Requires 2-6 sessions. It works, but the recovery is real and significant.

Deoxycholic acid targets adipocyte cell membranes, not melanin. Fat cell destruction and the subsequent inflammatory response are not affected by skin tone or Fitzpatrick type. Efficacy and risk profile are equivalent across all skin tones.
