Dalton Azelaic Acid Serum 10% is a high-concentration formula designed for skin prone to blemishes, acne, and redness. With 10% azelaic acid and antioxidant-rich green algae, this serum offers antibacterial properties that soothe redness caused by inflammation, making it perfect for couperose and rosacea-prone skin. It regulates sebum production, gently exfoliates, and unclogs pores, helping to treat, reduce, and prevent blackheads and other blemishes. The serum also provides antioxidant benefits, protecting the skin from oxidative stress and inflammation. While generally well tolerated, some may experience mild irritation, which usually subsides after a few weeks of use. Avoid combining with strong retinol, vitamin C, niacinamide, or chemical peels during the same time of day.
