Hi, I'm currently taking 1250mg of glutathione and 2500mg of Vitamin C twice a day (so, 750mg of glut and 1250mg of vitamin C in the morning, and 500mg of glut and 1000mg of Vitamin C in the afternoon) for skin lightening because I have dark spots that I would like to get rid of. Is it better if I take the dosage all at once or am I doing it correctly by taking it twice a day?

I tried the glutathione pills and thought it didn't help to lighten my skin at all and maybe even got darker :S
How is it working for you?
