Frequently asked questions
Can I use Polyglutamic Acid and Vitamin C together?
Yes, and they work even better together. Polyglutamic Acid cushions Vitamin C: it hydrates and supports the barrier while the active does its work. That means less irritation and better results.
Which goes first, Polyglutamic Acid or Vitamin C?
Apply Vitamin C first, then Polyglutamic Acid. The general rule is thinnest to thickest texture, and lowest pH first.
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.
Should I use Vitamin C in the morning or at night?
Vitamin C: best in the morning. Apply in the morning on clean skin before moisturiser and sunscreen. Store it away from light and heat, and throw it out once it turns dark orange.
