A small clinical trial reported that four weeks of oral glutathione supplementation led to a reduction in melanin index in certain sun-exposed areas, suggesting a measurable lightening effect in some individuals. Glutathione can influence skin tone in a few ways

It exerts anti-inflamatory effects by binding to melanocortin receptors (MC-Rs), inhibiting the release of inflamatory mediators, blocking the NF - B signaling pathway, and reducing the production of pro-inflamatory factors such as IL-1

Maintaining optimal levels of glutathione by supplementing the diet with whey protein is a useful nutritional approach to improving the outlook of CF patients

We do not prescribe GH-releasing peptides to patients whose IGF-1 is already in the high-normal range for their age, because stimulating further GH elevation in that context produces diminishing returns and increases the theoretical risk of side effects from GH excess
