In the mouse experiment of this cohort study, the investigators found that knocking out Keap1 resulted in the expression of Nrf2 target genes (such as GSH and NQO1), which supplemented the consumption of GSH in the oxidative stress response (Mohs et al., 2021)

Because liposomal delivery gets more glutathione into your cells per milligram, effective doses are lower, typically 250-500 mg per day, compared to the 5001,000 mg often required with standard oral tablets

Dermatologists usually start with controlled doses and adjust based on skin response
