Under the working assumption of a glutathione + vitamin C composition, studies report antioxidant effects through reactive-oxygen-species scavenging and inhibition of tyrosinase activity, which can lead to observed skin-pigmentation lightening. Observed in research settings.
Mechanistic statements are component-specific and rest on the UNVERIFIED working assumption of composition. A synergistic pharmacological rationale for the specific Glow Blend formulation has NOT been formally validated in peer-reviewed literature. Researchers who require a defined ratio should obtain glutathione and vitamin C separately.
