The format of this formula is a very fine, anhydrous, L-Ascorbic Acid powder and, as such, provides the most direct exposure of extremely high concentrations of Vitamin C topically. With such format, a very strong tingling but non-irritating sensation is expected during the first 1-2 weeks of use until the skin's tolerance to such high exposure is elevated.
Directions
Mix a small amount with other treatments in the palm of your hand and apply to face in the AM or the PM. Avoid contact with the eyes. A tingling sensation can be expected after application. Do not mix with formulations containing Niacinamide or EUK 134. 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.
