Alternative Cosmetic and Medical Applications of Injectable Deoxycholic Acid: A Systematic Review.

ABSTRACT

BACKGROUND: Beyond submental fat reduction, injectable deoxycholic acid (DCA) has gained popularity in recent years for various minimally invasive lipolysis applications. OBJECTIVE: To summarize and evaluate the evidence of off-label uses of injectable DCA. METHODS: MEDLINE, Embase, CINAHL, Web of Science, and CENTRAL were searched. The outcomes measured included applications of DCA, treatment regimen, and its efficacy. An overall success rate for each condition was calculated based on the improvement defined in the included studies. RESULTS: Eleven studies evaluated the cosmetic use of DCA for excess adipose tissue on various anatomical locations. The outcomes were evaluated at time points ranging from 1 to 21 months post-treatment, with overall success rates over 85%. Eight case reports and series reported the success of using DCA treating lipomas, xanthelasmas, paradoxical adipose hyperplasia, fibrofatty residue of infantile hemangioma, piezogenic pedal papules, and HIV-associated lipohypertrophy. Although the preliminary efficacies were high, the overall recommendations for off-label uses are weak because of the lack of high-level studies. CONCLUSION: The review emphasizes the diversity of injectable DCA as a minimally invasive technique for lipolysis. Further high-level studies demonstrating consistent treatment regimens and methods of evaluation are warranted to make more definitive recommendations regarding off-label DCA use.
