Safety, Tolerability & Regulatory Status Safety Profile GHK-Cu demonstrates an excellent safety profile for cosmetic use: Naturally occurring in humans (plasma, saliva, urine) Non-sensitizing in standard patch testing at cosmetic concentrations Long history of topical application in anti-aging and wound care products Minimal reported adverse reactions at appropriate doses Usage Levels and Tolerability Regulatory Status EU : Permitted as a cosmetic ingredient with standard safety assessments US/Asia-Pacific : Allowed under respective cosmetic regulations Formulators must : Perform product-specific safety evaluations, including SDS review, toxicological profiles, and margin of safety calculations Addressing Copper Uglies Literature occasionally references theoretical over-stimulation of MMPs leading to collagen breakdown (sometimes called copper uglies)
The ability of glutathione to modulate oxidative stress makes it a valuable therapeutic agent for conditions characterized by elevated ROS, such as cold sores and canker sores
[7] Most cysteine residues are covalently bonded to other cysteine residues to form disulfide bonds, which play an important role in the folding and stability of some proteins, usually proteins secreted to the extracellular medium
Reduced and oxidized glutathione can be converted into each other in the human body
