Frequently asked questions
Can I use PHA and Squalane together?
Yes, it is safe. There is no known chemical conflict between PHA and Squalane, and neither makes the other less effective. They share a goal (hydration), so together they reinforce each other.
Which goes first, PHA or Squalane?
Apply PHA first, then Squalane. 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 Squalane in the morning or at night?
Squalane: works morning or night. Press 2–3 drops in as the last step at night, or mix a drop into your moisturiser.
