Azelaic acid gel is used to clear the bumps, lesions, and swelling caused by rosacea (a skin disease that causes redness, flushing, and pimples on the face). Azelaic acid cream is used to treat acne. Azelaic acid is in a class of medications called dicarboxylic acids. It works to treat acne by killing the bacteria that infect pores and by decreasing production of keratin, a natural substance that can lead to the development of acne. The way azelaic acid works to treat rosacea is not known.
Azelaic acid comes as a gel and a cream to apply to the skin. It is usually applied twice a day, in the morning and the evening.
