Frequently asked questions
Can I use Polyglutamic Acid and Salicylic Acid together?
Yes, and they work even better together. Polyglutamic Acid cushions Salicylic Acid: it hydrates and supports the barrier while the active does its work. That means less irritation and better results.
Which goes first, Polyglutamic Acid or Salicylic Acid?
Apply Salicylic Acid first, then Polyglutamic Acid. The general rule is thinnest to thickest texture, and lowest pH first.
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.
Should I use Salicylic Acid in the morning or at night?
Salicylic Acid: works morning or night. Use as a cleanser daily or a leave-on 2% serum 3–4 times a week. It can dry out skin, so moisturise well.
Is Polyglutamic Acid with Salicylic Acid safe during pregnancy?
Neither is a known risk in normal cosmetic amounts, but guidance varies for Salicylic Acid. Check with your doctor.
