Transform your complexion with The Ordinary 100% L-Ascorbic Acid Powder, a very fine antioxidant powder that helps to brighten the appearance of skin while addressing signs of ageing.The fine 325 mesh powder formula ensures skin receives the most direct exposure of Vitamin C, a powerful ingredient that visibly targets uneven skin tone, dullness and ageing. Formulated to be mixed with other treatments (except those containing Niacinamide or EUK 134), the L-Ascorbic Acid powder will promote a radiant, more uniform and healthy-looking complexion. A tingling (but non-irritating) sensation is expected during the first 1-2 weeks of use.
