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