Frequently asked questions
Can I use Azelaic Acid and Tea Tree Oil together?
Yes, it is safe. There is no known chemical conflict between Azelaic Acid and Tea Tree Oil, and neither makes the other less effective. They share a goal (acne), so together they reinforce each other.
Which goes first, Azelaic Acid or Tea Tree Oil?
Apply Tea Tree Oil first, then Azelaic Acid. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Azelaic Acid in the morning or at night?
Azelaic Acid: works morning or night. Apply once or twice daily. A mild tingle in the first week is normal.
Should I use Tea Tree Oil in the morning or at night?
Tea Tree Oil: works morning or night. Use a product with around 5% tea tree, or dilute it. Never apply the pure oil straight to the face. Patch test first.
Is Azelaic Acid with Tea Tree Oil safe during pregnancy?
Neither is a known risk in normal cosmetic amounts, but guidance varies for Tea Tree Oil. Check with your doctor.
