Frequently asked questions
Can I use Hyaluronic Acid and PHA together?
Yes, it is safe. There is no known chemical conflict between Hyaluronic Acid and PHA, and neither makes the other less effective. They share a goal (hydration), so together they reinforce each other.
Which goes first, Hyaluronic Acid or PHA?
Apply PHA first, then Hyaluronic Acid. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Hyaluronic Acid in the morning or at night?
Hyaluronic Acid: works morning or night. Apply on slightly damp skin and seal with a moisturiser. In very dry air, skipping the seal can leave skin tighter.
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.
