what does azelaic acid do

Azelaic acid is a skin-friendly dicarboxylic acid that has antimicrobial and anti-inflammatory properties. It is a topical product that can be used to treat a variety of skin conditions, including acne, rosacea, melasma, and psoriasis vulgaris. Azelaic acid kills bacteria on the skin that cause acne by decreasing the activity of bacteria called Propionibacterium. It also has antibacterial properties that help to unclog pores, reduce inflammation, and treat acne. Azelaic acid is milder than other acne-fighting ingredients like salicylic acid and adapalene, making it more suitable for those with sensitive skin, acne, and rosacea. Additionally, it is a tyrosinase inhibitor that helps to even out skin tone and prevent and treat hyperpigmentation due to conditions like melasma. Azelaic acid is safe and gentle, with minimal side effects, and can be used in children and people who are pregnant or breastfeeding. Common side effects of azelaic acid can include burning or stinging, itchiness, dryness, peeling skin, and redness, but these usually go away after 2 to 4 weeks of treatment. It is important to talk to a doctor or dermatologist before using azelaic acid, especially if you have sensitive skin or are using other skincare products.
