Ultraviolet light is causing oxidative stress and that is damaging to the skin.
This also leads to the depletion of important cellular antioxidants, especially glutathione, which you may have guessed.
Glutathione is a very effective antioxidant.
Glutathione protects the liver, it’s involved in detoxification, and it also regulates the immune system.
The body is making this antioxidant, but the problem is that it is making less as we get older.
When we get into our forties, we start to make approximately 10% less each year.
The logical solution would be to take glutathione, but regular glutathione is not effective as a treatment, because it is oxidized (damaged in the stomach).
For that reason the researchers in this study used S-Acetyl Glutathione because that has been shown to effectively get into the cells.
The research showed that the S-Acetyl Glutathione increased the intra cellular glutathione level and protected against ultraviolet induced free radical damage and lipid peroxidation (Wright D, et al. 2013).
Most of the glutathione on the market is not getting into the cells where it is needed.
To ensure that you receive the benefits of glutathione use S-Acetyl Glutathione.

Glutathione is your primary defense against aging, but regular glutathione is oxidized (destroyed in the stomach) and provides little value. S-Acetyl Glutathione is easily absorbed and provides protection.
