Azelaic acid is a naturally occurring acid found in grains such as barley, wheat, and rye. The ingredient has antimicrobial and anti-inflammatory properties, which make it effective in the treatment of skin conditions like acne and rosacea.
Azelaic acid helps clear your pores of bacteria that may be causing irritation or breakouts. It also reduces inflammation, so acne becomes less visible, less red and less irritated. The gentle exfoliation encourages cell turnover, which helps your skin heal more quickly and minimizes scarring.
