Although "reduced glutathione" has a powerful effect, it has a fatal disadvantage, that is, it is afraid of light, water, and high temperature, and its stability is poor. "Reduced glutathione" is dissolved in an aqueous solution and can only be stored for 2 hours at room temperature, and it can only be stored for 8 hours at 0 to 5°C.
Reduced glutathione is used as a medicine in medicine, whether it is injected subcutaneously or intravenously, it is in the form of freeze-dried powder. Whether the powder ampoule is transported or stored, it must be refrigerated or frozen. Dissolve it before use, and use it first to fully maintain its activity and effectiveness.
When some small partners are doing medical beauty injections, if the core component of the whitening needle is reduced glutathione, as long as it is not dissolved before the glutathione powder injection, it is a pre-prepared "whitening needle", glutathione Peptides have been oxidized and very little remains, and it is difficult to function.
Reduced glutathione added in cosmetics, as long as it is added to lotions, essences, lotions, and creams, it is difficult to maintain long-term activity and will quickly oxidize and decompose. When consumers use it, it has no value.
Most of the reduced glutathione in whitening pills and health foods has been stored in powder form, and the shelf life will be longer. However, whether reduced glutathione can be stored for a long time at room temperature, I have not found relevant literature. However, referring to the need to refrigerate or freeze glutathione, which is used to treat diseases, it is guessed that its activity must decay faster at room temperature. In addition, studies have shown that after oral glutathione enters the human body, the bioavailability is extremely low. The effect of oral glutathione on the human body is controversial.
In summary, "Glutathione" is an excellent ingredient with a wide range of applications. It has good effects in scavenging free radicals, anti-oxidation, whitening, and spot-lightening. However, the stability of "glutathione" is too poor, which limits its effectiveness. There are many cosmetics that add "glutathione", but most of them cannot play their original role.
