Frequently asked questions
Can I use Niacinamide and Zinc PCA together?
Yes, and they work even better together. A classic oil-control duo: niacinamide calms redness and tightens the look of pores while zinc helps regulate sebum. Many serums combine them.
Which goes first, Niacinamide or Zinc PCA?
Apply Niacinamide first, then Zinc PCA. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Niacinamide in the morning or at night?
Niacinamide: works morning or night. Use morning, night or both, after water-based serums. 4–5% is enough for most people. Very high percentages can cause flushing on sensitive skin.
Should I use Zinc PCA in the morning or at night?
Zinc PCA: works morning or night. Use once or twice daily. It works best as part of a niacinamide or oil-control serum.
