Hi everyone, I really want to lighten my skin tone to at least 3 shades lighter, and I was thinking about using glutathione pills to do that, now I've reading the forums, and dr. james and active white is brought up very frequently, so I wanted to try them out, but I've looked them up on the web and the cheapest I've found those brands was for 36 dollars a bottle, now to me that's really expensive, so I started looking at sum vitamin sites online and I found sum glutathione pills for a lot cheaper, but the only thing was it wasn't any name brand or anything, so my question is, isn't glutathione glutathione, I mean doesn't it all have the same ingredients and effects as all glutathione pills no matter what brand you get ?
