Azelaic acid is a topical medication that is used to treat a variety of skin conditions, including hormonal acne. Hormonal acne is caused by an overproduction of androgens, which leads to an increase in sebum production and inflammation of the skin. Azelaic acid helps to reduce the severity of hormonal acne by targeting these underlying factors.
Firstly, azelaic acid works as an antibacterial agent by inhibiting the growth of Propionibacterium acnes, a bacteria commonly associated with acne. By reducing the number of bacteria on the skin, azelaic acid helps to decrease inflammation and prevent the formation of new acne lesions.
Secondly, azelaic acid has anti-inflammatory properties that can help to reduce the redness and swelling associated with acne. Inflammation is a key factor in the development of acne, and by reducing inflammation, azelaic acid can help to improve the appearance of the skin.
