Frequently asked questions
Can I use Mandelic Acid and Zinc PCA together?
Yes, it is safe. There is no known chemical conflict between Mandelic Acid and Zinc PCA, and neither makes the other less effective. They share a goal (acne), so together they reinforce each other.
Which goes first, Mandelic Acid or Zinc PCA?
Apply Mandelic Acid first, then Zinc PCA. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Mandelic Acid in the morning or at night?
Mandelic Acid: best at night. Use 3–4 nights a week. It is mild enough that many people can use it more often than other acids.
Should I use Zinc PCA in the morning or at night?
Zinc PCA: works morning or night. Use once or twice daily. It works best as part of a niacinamide or oil-control serum.
