Frequently asked questions
Can I use Peptides and Polyglutamic Acid together?
Yes, it is safe. There is no known chemical conflict between Peptides and Polyglutamic Acid, and neither makes the other less effective. They share a goal (barrier and hydration), so together they reinforce each other.
Which goes first, Peptides or Polyglutamic Acid?
Apply Polyglutamic Acid first, then Peptides. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Peptides in the morning or at night?
Peptides: works morning or night. Use morning and night after water-based serums. Low-pH acids applied at the same time can break some peptides down.
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.
