What glutathione IV actually does for skin
Glutathione is the most heavily promoted active in beauty-IV protocols, and the one most likely to be over-claimed. The biology is real but specific. The clinical question is what is supported and what is marketing.
Glutathione (GSH) is a tripeptide built from glutamate, cysteine, and glycine. It is one of the principal intracellular antioxidants in human tissue and a substrate in detoxification pathways in the liver and skin.
What glutathione does in skin
Inhibits tyrosinase, the enzyme that converts tyrosine into melanin. Reducing tyrosinase activity reduces eumelanin synthesis and shifts the melanin balance toward lighter pheomelanin. This is the mechanism behind the tone-clarification effects observed in glutathione protocols.
Recycles oxidized vitamin C and vitamin E in tissue. This expands the functional antioxidant capacity of skin under UV and inflammatory stress.
Supports detoxification of reactive metabolites in the skin and liver. The clinical relevance varies by individual metabolic load.
What is and isn't supported
Supported by the literature: reduction in UV-induced erythema markers, more even tone across 4–8 weeks of dosing, modest reduction in hyperpigmentation in some populations. Effects are dose-dependent and recur with repeated administration.
Not supported as a clinical claim: skin whitening as a cosmetic goal. The FDA has issued warnings against marketing IV glutathione for skin lightening. Beauty Elite at INFUZE is structured around tone clarity and antioxidant support, not depigmentation.
Why the 4-week protocol
The visible skin layer renews on a ~28-day cycle. Effects on tone clarity become apparent as cells affected by the antioxidant support cycle through to the surface. A single session is invisible; the 4-week protocol covers one full renewal. Monthly maintenance preserves the effect.
Liver markers (ALT, AST, GGT) are baselined before the protocol and reviewed every 12 weeks on extended use. Glutathione is generally well tolerated, but ongoing dosing warrants documentation.
Common questions
- Is Beauty Elite safe long-term?
- The 4-week induction followed by monthly maintenance is well tolerated. We monitor liver markers every 12 weeks for clients on extended protocols.
- Will my skin lighten?
- Beauty Elite can produce more even tone by reducing accumulated oxidative damage, but is not formulated or marketed for depigmentation. The clinical goal is tone clarity against your starting baseline.
- How fast will I see results?
- Most clients notice tone improvement by week 2 of the 4-week protocol. Texture and clarity changes build across weeks 4–8.
