Azelaic Acid Serum from Korea
Azelaic acid occurs naturally in grains. In skincare, it's used for redness-prone, unsettled skin and for blemishes. Cosmetics usually contain up to 10%, while higher concentrations are available as medicines from the pharmacy.

How to use it
After your toner, apply the serum in a thin layer, in the evening at first, and later in the morning too. A slight tingling at the beginning is normal. Azelaic acid works well with Niacinamide. In the morning, follow with sun protection.
