###Human: Is it safe to use IV Glutathione to get lighter skin? ###Assistant: Hello. Injectable Glutathione is not FDA approved. Still, it is used by many people to reduce the skin tone by two to three shades. It is a once-a-week injection for four weeks, then once in two weeks for four weeks. If there is no response after three to four sessions then further treatment should not be taken. I personally would not advise taking IV Glutathione as the results are not permanent. Skin color changes back to the normal tone after three to six months of stopping treatment. For more information consult a cosmetologist online -->
