How to use

After cleansing, apply a few drops at the serum step and massage in from the center of the face outward. Use morning or evening; if used in the morning, follow with SPF 30 or higher.

Pros
  • 15% niacinamide with zinc PCA for oil and pore appearance
  • Light, fast-absorbing texture with no residue, per the brand
  • Can be used morning or evening
Cons
  • Trials mostly used 2-5% niacinamide, so 15% is not proven to work better and may sting or flush some skin
  • The zinc evidence is thinner than the niacinamide evidence
  • Percentage results on the page are the brand's own and not independently verified
