Frequently asked questions
Can I use Glutathione and Glycolic Acid together?
Yes, it is safe. There is no known chemical conflict between Glutathione and Glycolic Acid, and neither makes the other less effective. They share a goal (pigmentation and dullness), so together they reinforce each other.
Which goes first, Glutathione or Glycolic Acid?
Apply Glycolic 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.
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.
Is Glutathione with Glycolic Acid safe during pregnancy?
Neither is a known risk in normal cosmetic amounts, but guidance varies for Glutathione. Check with your doctor.
