What it is

Azelaic acid is a dicarboxylic acid with antibacterial, anti-inflammatory, and tyrosinase-inhibiting properties. It is used for inflammatory acne, post-acne marks, and persistent redness, especially in rosacea-prone skin. K-beauty over-the-counter products typically dose it at 5–10%; higher percentages are prescription in many markets.
