Frequently asked questions
Can I use Glycolic Acid and Polyglutamic Acid together?
Yes, and they work even better together. Polyglutamic Acid cushions Glycolic Acid: it hydrates and supports the barrier while the active does its work. That means less irritation and better results.
Which goes first, Glycolic Acid or Polyglutamic Acid?
Apply Glycolic Acid first, then Polyglutamic Acid. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Glycolic Acid in the morning or at night?
Glycolic Acid: best at night. Use 2–3 nights a week after cleansing. Skip it on nights you use retinoids. Sunscreen is non-negotiable because AHAs raise sun sensitivity.
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.
