How to Use: After cleansing and toning, apply a few drops of serum and pat gently. Due to the high concentration of azelaic acid, slight residue or filming may occur. For better absorption, apply a thin layer at a time and allow the formula to absorb completely before applying another layer. For external use only. Always patch test. Discontinue use if you feel any discomfort. Follow additional instructions on packaging. Individual results may vary.
