What is azelaic acid gel, and how does it work (mechanism of action)?
- Azelaic acid is a topical (applied to the skin) medication used for treating
acne. Its exact mechanism of action is unknown. Azelaic acid may work as an
antibacterial agent that blocks protein synthesis and therefore growth of
Propionibacterium acnes and other bacteria on the surface of the skin that are
associated with the development of acne. It may also inhibit follicular
keratinization, which prevents development of acne lesions. The FDA approved
azelaic acid in September 1995. - References: FDA prescribing information
