Frequently asked questions
Can I use Glutathione and Polyglutamic Acid together?
Yes, it is safe. There is no known chemical conflict between Glutathione and Polyglutamic Acid, and neither makes the other less effective.
Which goes first, Glutathione or Polyglutamic Acid?
Apply Polyglutamic Acid first, then Glutathione. The general rule is thinnest to thickest texture, and lowest pH first.
Should I use Glutathione in the morning or at night?
Glutathione: works morning or night. Use daily as part of a brightening routine, always with sunscreen. Glutathione injections and drips for skin whitening are not approved for that use and carry real risks.
