Frequently asked questions
Can I use Retinol and Zinc PCA together?
Yes, it is safe. There is no known chemical conflict between Retinol and Zinc PCA, and neither makes the other less effective. They share a goal (acne), so together they reinforce each other.
Which goes first, Retinol or Zinc PCA?
Apply Zinc PCA first, then Retinol. The general rule is thinnest to thickest texture, and lowest pH first.
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.
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.
Is Retinol with Zinc PCA safe during pregnancy?
Retinol is generally avoided during pregnancy and breastfeeding. Ask your doctor about safer alternatives such as azelaic acid or bakuchiol.
