A-Control 10% Azelaic Acid Serum - 30ml

Nine Less A-Control 10% Azelaic Acid Serum is a Korean blemish and redness-care serum made for acne-prone, oily, combination, congested or uneven-looking skin. The formula contains 10% Azelaic Acid to help improve the appearance of blemishes, post-acne marks, redness and uneven tone, while Niacinamide supports brighter-looking skin and helps refine the appearance of enlarged pores.

After cleansing and toner, apply 2–3 drops evenly over the face and neck, avoiding the immediate eye area. Gently pat until absorbed, then follow with moisturizer. It may also be mixed with a moisturizer or another compatible hydrating serum.

If you are new to Azelaic Acid or have sensitive skin, begin once daily or every other day and gradually increase according to your skin's comfort. Nine Less states that the serum can be used in both morning and evening routines.

Apply sunscreen during the daytime. Avoid using on broken or severely irritated skin. If combining with strong exfoliating acids, retinoids or other intensive actives, introduce products gradually to reduce the chance of irritation. Discontinue or reduce frequency if persistent irritation occurs.
