What Is Azelaic Acid?

Azalaic acid is a dicarboxylic acid that has profound skin-soothing and brightening effects, helping to unclog the pores and revitalize the surface of the skin - evening skin tone, fading discoloration and smoothing the skin. It is naturally occurring (and can be obtained from grains such as barley, wheat and rye) but is often lab-produced for skincare.
