The Ordinary Niacinamide 10% + Zinc 1% 30ml

High-strength vitamin and mineral blemish formula that visibly regulates sebum and minimizes pores. This product has no safety seal
Niacinamide (Vitamin B3) is indicated to reduce the appearance of skin blemishes and congestion. A high 10% concentration of this vitamin is supported in the formula by zinc salt of pyrrolidone carboxylic acid to balance visible aspects of sebum activity.
Contraindications: If topical Vitamin C (L-Ascorbic Acid and/or Ethylated L-Ascorbic Acid) is used as part of skincare, it should be applied at alternate times with this formula (ideally Vitamin C in the PM and this formula in the AM). Otherwise, Niacinamide can affect integrity of the Vitamin C.
Independent studies suggest Niacinamide is also an effective ingredient for brightening skin tone.
Apply to entire face morning and evening before heavier creams. If irritation occurs, cease use and consult a physician.
