Lipolytic agents for submental fat reduction: Review.

Abstract

The review delves into the realm of reducing submental fat, presenting a comprehensive analysis of various lipolytic agents used in plastic surgery and dermatology. The introduction establishes the context by defining the key indicators of a youthful neck and emphasizing the significant influence of fat in the aging process, particularly in the submental area. The usage of aminophylline involves subcutaneous injections, facilitating fat breakdown by increasing cyclic adenosine monophosphate and inhibiting adenosine receptors. Hypotonic pharmacologic lipo-dissolution induces fat dissolution via injected compounds under pressure, while lipolytic lymphatic drainage employs hyaluronidase to reduce tissue viscosity, aiding fat circulation. Glycerophosphorylcholine containing choline alfoscerate claims to activate fat metabolism, whereas the utilization of phosphatidylcholine combined with deoxycholate lacks cosmetic approval due to safety concerns. Deoxycholic acid has FDA approval for submental fat reduction, yet its mechanisms remain incompletely understood. Understanding the complex anatomy and mechanisms of lipolytic agents is essential for safe and effective submental fat reduction, despite evolving practices and off-label utilization. Clinical guidelines and references support this discussion, offering insights for safer applications.
