Frequently asked questions
Can I use Polyglutamic Acid and Retinol together?
Yes, and they work even better together. Polyglutamic Acid cushions Retinol: 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 Retinol?
Apply Polyglutamic Acid first, then Retinol. 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 Retinol in the morning or at night?
Retinol: best at night. Start 2–3 nights a week on dry skin, a pea-sized amount for the whole face, then build up. Always wear sunscreen the next morning.
Is Polyglutamic Acid with Retinol safe during pregnancy?
Retinol is generally avoided during pregnancy and breastfeeding. Ask your doctor about safer alternatives such as azelaic acid or bakuchiol.
