The Ordinary 100% L-Ascorbic Acid Powder offers a very fine L-Ascorbic Acid powder that visibly targets the appearance of uneven skin tone, dullness, and signs of aging and is formulated to be mixed with other treatments (except those containing Niacinamide or EUK 134). The format of this formula is a suspension of very fine 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. If topical Vitamin C is used as part of skincare, it should be applied at alternate times with EUK 134 or Niacinamide (ideally Vitamin C in the PM and EUK 134/Niacinamide in the AM). Otherwise, EUK 134/Niacinamide can affect the integrity of pure-form Vitamin C (L-Ascorbic Acid). This formula is water-free, alcohol-free, oil-free, silicone-free, nut-free, gluten-free and vegan. The Ordinary is a cruelty-free brand; they do not test any of their products on animals. Directions: Mix a small amount with other treatments in the palm of your hand and apply to face in the AM or the PM. A tingling sensation can be expected after application. Do not mix with formulations containing Niacinamide or EUK 134. Ingredients: Ascorbic Acid.
