LC-MS for Metabolite Determination According to our targeted metabolomic experiment, potential metabolite markers were quantitated by comparing the areas of the peaks corresponding to the unlabelled compounds to the areas of the peaks for the external standards (method validation is shown in Supplementary Method II, Supplementary Tables S4, S5, and Supplementary Figure S2) (Liu et al., 2015)
A local injection-site reaction Intramuscular injections can leave the area sore, red, warm or slightly swollen for a day or two
Regulates Melanin for Even Skin Tone Glutathione inhibits the enzyme tyrosinase, shifting melanin production from dark pigment (eumelanin) to light pigment (pheomelanin), helping your skin appear brighter and more uniform over time
