Use in serums, creams, lotions, and sheet masks for brighter, healthier-looking skin. Not to be confused with glutathione supplements, this powder is for external use in cosmetics only.

Q1: Can I use L-Glutathione every day in skincare?

Yes, it's suitable for daily use when formulated correctly and used in low concentrations.

Q2: Does this whiten skin permanently?

It helps in brightening and evening out the skin tone over time but does not bleach or cause permanent lightening.

Q3: Is it safe for sensitive skin?

It's best to patch test first. For very sensitive skin, use with soothing agents like aloe or panthenol.
