This formula combines very high concentrations of two of the most powerful and important antioxidants in skincare: Resveratrol and Ferulic Acid. Resveratrol is a natural phenol found in several plants and our pure source is 100% derived from Japanese Knotweed. Ferulic Acid is a high-potency phytochemical antioxidant found naturally in walls of plant cells. Skincare formulations generally incorporate Resveratrol at 1% or less and Ferulic Acid at 0.5% or less. This formula contains each at 3%, an exceptionally high concentration. Note: Water can impair the stability of any antioxidant. This formula does not contain any water, silicones, oils or alcohol. Direction: 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. Do not use on sensitive, peeling or compromised skin. If irritation occurs, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Keep out of reach of children. Do not refrigerate.
