Use the Anua Azelaic Acid 10 Hyaluron Redness Soothing Serum in your morning or evening routine.
After cleansing and toning, apply 1–2 drops evenly across your face, and then gently pat to help it absorb.
Follow with moisturizer.
If you're new to azelaic acid, start slow using the serum 1–2 times a week to let your skin adjust. Once it feels comfortable, you can apply it twice daily and increase to 3–5 drops.
