Frequently asked questions
Can I use Benzoyl Peroxide and Niacinamide together?
Yes, it is safe. There is no known chemical conflict between Benzoyl Peroxide and Niacinamide, and neither makes the other less effective. They share a goal (acne), so together they reinforce each other.
Which goes first, Benzoyl Peroxide or Niacinamide?
Apply Benzoyl Peroxide first, then Niacinamide. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Benzoyl Peroxide in the morning or at night?
Benzoyl Peroxide: works morning or night. 2.5% works about as well as 10% and irritates less. Use as a short-contact wash or a spot treatment, and keep it away from fabrics.
Should I use Niacinamide in the morning or at night?
Niacinamide: works morning or night. Use morning, night or both, after water-based serums. 4–5% is enough for most people. Very high percentages can cause flushing on sensitive skin.
Is Benzoyl Peroxide with Niacinamide safe during pregnancy?
Neither is a known risk in normal cosmetic amounts, but guidance varies for Benzoyl Peroxide. Check with your doctor.
