Frequently asked questions
Can I use Azelaic Acid and Retinal together?
Yes, it is safe. There is no known chemical conflict between Azelaic Acid and Retinal, 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 Retinal?
Apply Azelaic Acid first, then Retinal. 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 Retinal in the morning or at night?
Retinal: best at night. Start at 0.05% two or three nights a week and build up slowly. Buffer with moisturiser if you are sensitive, and wear SPF daily.
Is Azelaic Acid with Retinal safe during pregnancy?
Retinal is generally avoided during pregnancy and breastfeeding. Ask your doctor about safer alternatives such as azelaic acid or bakuchiol.
