Frequently asked questions
Can I use Sulfur and Zinc PCA together?
Yes, it is safe. There is no known chemical conflict between Sulfur and Zinc PCA, and neither makes the other less effective. They share a goal (acne and oil control), so together they reinforce each other.
Which goes first, Sulfur or Zinc PCA?
Apply Zinc PCA first, then Sulfur. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Sulfur in the morning or at night?
Sulfur: works morning or night. Use as a spot treatment, a clay mask or a short-contact wash. It can be drying, so moisturise afterwards.
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.
