The Ordinary 100% L-Ascorbic Acid Powder 20g

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.

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.
