Frequently asked questions
Can I use Niacinamide and Polyglutamic Acid together?
Yes, it is safe. There is no known chemical conflict between Niacinamide and Polyglutamic Acid, and neither makes the other less effective. They share a goal (barrier), so together they reinforce each other.
Which goes first, Niacinamide or Polyglutamic Acid?
Apply Polyglutamic Acid first, then Niacinamide. 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 Polyglutamic Acid in the morning or at night?
Polyglutamic Acid: works morning or night. Apply after toner and before moisturiser, morning or night.
