When (and how) to use Resveratrol 3% + Ferulic Acid 3% by The Ordinary

Apply alone or after water-based serums, before oils or heavier creams. Alternatively, mix with other treatments to enhance their antioxidant capacity significantly. This treatment is highly concentrated and can be diluted with most oils per application to reduce strength. A small amount of Resveratrol 3% and Ferulic Acid 3% and The Ordinary Vitamin C Suspension 23% + HA Spheres 2% or Vitamin C Suspension 30% in Silicone can be diluted in any one of our oils at each application to form an outstanding antioxidant network of Vitamin C, Ferulic Acid and Resveratrol in lipids. It is recommended to keep this mixture at low strength. If irritation occurs, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised.
