Deoxycholic acid is widely used in the medical field, particularly in cosmetic and therapeutic procedures. It is an active ingredient in injectable treatments designed to reduce submental fat, commonly known as a double chin. When injected into the fat tissue, it disrupts the cell membrane, causing the fat cells to break down and be naturally eliminated by the body. This non-surgical approach is favored for its minimal downtime and effectiveness in contouring the jawline.

In addition to its cosmetic applications, deoxycholic acid plays a role in the pharmaceutical industry as a component of bile acid formulations used to treat certain digestive disorders. It aids in the emulsification and absorption of fats and fat-soluble vitamins in the intestines, making it beneficial for patients with bile deficiency or fat malabsorption issues.

Research is also exploring its potential in drug delivery systems, where it can enhance the solubility and bioavailability of poorly water-soluble drugs. Its ability to interact with cell membranes makes it a promising candidate for improving the efficacy of various therapeutic agents.

Furthermore, deoxycholic acid is utilized in laboratory settings for the extraction of DNA and RNA from cells, owing to its property of dissolving cell membranes, which facilitates the isolation of genetic material.
