Is glutathione effective for fatigue recovery and skin whitening?

Since it's spring, with large daily temperature variations and frequent temperature changes, I often feel tired.

I am trying glutathione because it is said to have good antioxidant effects.

This is a granular type, and it's sweet and sour, quite tasty.

Some people take glutathione that you put in your mouth, but I haven't tried that.

Is the topical glutathione more effective?

I'm curious about how effective it is for those who take it~

They say that consistently taking glutathione is also effective for skin whitening.

It would be nice if there was an effect to address the dark and dull skin tone.

I'm curious if there are any people who have experienced effects.
