Azelaic acid

A naturally occurring acid found in grains such as barley, wheat, and rye, known for its antimicrobial and anti-inflammatory properties. It is effective in treating skin conditions like acne and rosacea by killing bacteria that infect pores and reducing the production of keratin, which can lead to acne development. Azelaic acid is primarily used by individuals with acne-prone or rosacea-affected skin seeking a treatment to improve their skin condition.
