Frequently asked questions
Can I use Benzoyl Peroxide and Polyglutamic Acid together?
Yes, and they work even better together. Polyglutamic Acid cushions Benzoyl Peroxide: it hydrates and supports the barrier while the active does its work. That means less irritation and better results.
Which goes first, Benzoyl Peroxide or Polyglutamic Acid?
Apply Benzoyl Peroxide first, then Polyglutamic Acid. 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 Polyglutamic Acid in the morning or at night?
Polyglutamic Acid: works morning or night. Apply after toner and before moisturiser, morning or night.
Is Benzoyl Peroxide with Polyglutamic Acid safe during pregnancy?
Neither is a known risk in normal cosmetic amounts, but guidance varies for Benzoyl Peroxide. Check with your doctor.
