Azelaic Acid

Azelaic acid cream is used to treat the pimples and swelling caused by acne. Azelaic acid is in a class of medications called dicarboxylic acids. It works to treat rosacea by decreasing the swelling and redness of the skin. 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.
