Description

COSRX The Niacinamide 15 Serum is a compact 20 mL facial serum with 15% niacinamide. Compare both its bottle size and formula when deciding between niacinamide treatments.

Formula details

  • Size: 20 mL
  • Niacinamide: 15%
  • Supporting ingredients listed include zinc PCA, panthenol and sodium hyaluronate
  • Leave-on facial serum

Before you choose

The smaller bottle can have a different cost per mL from a 30 mL or 40 mL serum. Concentration and bottle volume measure different things; neither alone predicts your experience with the finished formula.

Follow the current label directions and introduce gradually. Review other treatments in your routine before adding another concentrated serum.

Compare serum sizes and value or explore niacinamide formulas.
