Frequently asked questions
Can I use Ferulic Acid and Lactic Acid together?
Yes, it is safe. There is no known chemical conflict between Ferulic Acid and Lactic Acid, and neither makes the other less effective.
Which goes first, Ferulic Acid or Lactic Acid?
Apply Ferulic Acid first, then Lactic Acid. 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 Lactic Acid in the morning or at night?
Lactic Acid: best at night. Use 2–3 nights a week. It is good for beginners to exfoliation. Follow with a moisturiser, and wear SPF the next day.
