Azelaic Topical Acid

A high-concentration serum featuring a 10% azelaic acid derivative, niacinamide, and vitamin C to target congestion and uneven tone. It uses Potassium Azeloyl Diglycinate, a water-soluble form of azelaic acid that’s easier to layer and less gritty than traditional suspensions. This is the one to reach for when you're dealing with stubborn congestion but aren't looking for a harsh peel—it’s steady, effective, and plays well with the rest of your routine.
