Frequently asked questions
Can I use Benzoyl Peroxide and Vitamin C together?
No, keep them apart. Benzoyl peroxide oxidises vitamin C, making both less effective. Keep them in separate routines: vitamin C in the morning and benzoyl peroxide at night.
Which goes first, Benzoyl Peroxide or Vitamin C?
Apply Vitamin C first, then Benzoyl Peroxide. The general rule is thinnest to thickest texture, and lowest pH first. For this pair, though, it is better not to layer them in the same routine at all.
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 Vitamin C in the morning or at night?
Vitamin C: best in the morning. Apply in the morning on clean skin before moisturiser and sunscreen. Store it away from light and heat, and throw it out once it turns dark orange.
Is Benzoyl Peroxide with Vitamin C safe during pregnancy?
Neither is a known risk in normal cosmetic amounts, but guidance varies for Benzoyl Peroxide. Check with your doctor.
