The Ordinary Niacinamide 10% + Zinc PCA 1% is a skin treatment serum for blemishes and balancing sebum.
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 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 pure-form Vitamin C (L-Ascorbic Acid).
Note: While Niacinamide and Zinc PCA reduce the look of blemishes and balance visible sebum activity, neither is a treatment for acne. For persistent acne-related conditions, it is recommended to use Benzoyl Peroxide and/or Retinoic Acid. Deciem do not recommend the use of Salicylic Acid.
The Ordinary Niacinamide + Zinc formulation can be used alongside acne treatments if desired for added visible skin benefits.
Directions: Apply Niacinamide serum to entire face morning and evening before heavier creams.
