Can you use Polyglutamic Acid with Vitamin C?

Great combo

Yes, and they work even better together.

Polyglutamic Acid cushions Vitamin C: it hydrates and supports the barrier while the active does its work. That means less irritation and better results.

How to use them

Use them in the same routine in the morning. Apply Vitamin C first, then Polyglutamic Acid, moving from thinnest to thickest texture. Finish with sunscreen in the morning.
