Say Goodbye to Stomach Fat with Just an Injection – The Kybella Treatment The Kybella treatment is made up of one powerful injection. As of the moment, it is the only injectable treatment approved by FDA to be used to reduce the fat under the chin, to eliminate what is more commonly known as the “double chin”. However, dermatologists and aestheticians worldwide are slowly recognizing Kybella injections for other uses, not just to eliminate the fat under the chin, but also other parts of the body. Say goodbye to flabby arms, thigh saddlebags, love handles and more.
