Why you need it:
The Ordinary 100% L-Ascorbic Acid Powder is a very fine, pure Vitamin C powder to mix with moisturiser or serum. Vitamin C is an effective antioxidant that brightens the skin tone and reduces the appearance of signs of aging. This formula 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).
It should not be apply at the same time as The Ordinary EUK 134 0.1% or The Ordinary Niacinamide 10% + Zinc 1%. (Ideally use 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).
