Can I use Azelaic Acid and Urea together?
Yes, it is safe. There is no known chemical conflict between Azelaic Acid and Urea, and neither makes the other less effective.
Which goes first, Azelaic Acid or Urea?
Apply Azelaic Acid first, then Urea. 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.

Urea: works morning or night. Use 5–10% on the face or body daily. Higher strengths can sting on broken or freshly exfoliated skin.
