Frequently asked questions
Can I use Kojic Acid and Retinol together?
Yes, it is safe. There is no known chemical conflict between Kojic Acid and Retinol, and neither makes the other less effective. They share a goal (pigmentation), so together they reinforce each other.
Which goes first, Kojic Acid or Retinol?
Apply Kojic Acid first, then Retinol. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Kojic Acid in the morning or at night?
Kojic Acid: works morning or night. Patch test first. Use once daily at first, then build up.
Should I use Retinol in the morning or at night?
Retinol: best at night. Start 2–3 nights a week on dry skin, a pea-sized amount for the whole face, then build up. Always wear sunscreen the next morning.
Is Kojic Acid with Retinol safe during pregnancy?
Retinol is generally avoided during pregnancy and breastfeeding. Ask your doctor about safer alternatives such as azelaic acid or bakuchiol.
