The TIRTIR Azelaic Acid 12% Serum is a concentrated treatment for blemishes, redness, and excess sebum. 12% azelaic acid supports a clearer, more even-looking complexion. Zinc PCA helps regulate excess sebum, while panthenol and betaine soothe stressed skin and provide moisture. Ceramide NP and hydrogenated lecithin support the skin barrier. Hyaluronic acid, sorbitol, and plant sugars round out the formula with hydration so that the skin remains supple despite the high concentration of active ingredients.
