Frequently asked questions
Can I use Ferulic Acid and Tretinoin together?
Yes, it is safe. There is no known chemical conflict between Ferulic Acid and Tretinoin, and neither makes the other less effective. They share a goal (aging), so together they reinforce each other.
Which goes first, Ferulic Acid or Tretinoin?
Apply Ferulic Acid first, then Tretinoin. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Ferulic Acid in the morning or at night?
Ferulic Acid: best in the morning. Use in the morning under sunscreen, ideally in a combined C + E + Ferulic serum.
Should I use Tretinoin in the morning or at night?
Tretinoin: best at night. Use only as prescribed: a pea-sized amount on completely dry skin at night, starting 2–3 nights a week. Expect dryness and a possible purge for 4–8 weeks. Daily SPF is essential.
Is Ferulic Acid with Tretinoin safe during pregnancy?
Tretinoin is generally avoided during pregnancy and breastfeeding. Ask your doctor about safer alternatives such as azelaic acid or bakuchiol.
