Frequently asked questions
Can I use Azelaic Acid and Mandelic Acid together?
Yes, it is safe. There is no known chemical conflict between Azelaic Acid and Mandelic Acid, and neither makes the other less effective. They share a goal (acne and pigmentation), so together they reinforce each other.
Which goes first, Azelaic Acid or Mandelic Acid?
Apply Mandelic Acid 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 Mandelic Acid in the morning or at night?
Mandelic Acid: best at night. Use 3–4 nights a week. It is mild enough that many people can use it more often than other acids.
