Frequently asked questions
Can I use PHA and Tranexamic Acid together?
Yes, it is safe. There is no known chemical conflict between PHA and Tranexamic Acid, and neither makes the other less effective.
Which goes first, PHA or Tranexamic Acid?
Apply PHA first, then Tranexamic 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 Tranexamic Acid in the morning or at night?
Tranexamic Acid: works morning or night. Use once or twice daily for at least 8–12 weeks. It works best alongside a daily broad-spectrum sunscreen.
Is PHA with Tranexamic Acid safe during pregnancy?
Neither is a known risk in normal cosmetic amounts, but guidance varies for Tranexamic Acid. Check with your doctor.
