Frequently asked questions
Can I use PHA and Polyglutamic Acid together?
Yes, it is safe. There is no known chemical conflict between PHA and Polyglutamic Acid, and neither makes the other less effective. They share a goal (hydration), so together they reinforce each other.
Which goes first, PHA or Polyglutamic Acid?
Apply PHA first, then Polyglutamic Acid. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use PHA in the morning or at night?
PHA: works morning or night. You can use it daily. It is a good first acid, or a way to keep exfoliating on retinoid "rest" nights if your skin tolerates it.
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.
