if your concern is your stretch mark, glutathione is not an naswer to that my dear, this product is for skin lightening...
stretch mark can no longer be eliminated once it is there, the best thing you can do is to make it less visible, try using palmers cocoa butter lotion. and one thing too, you have to be patient in treating them because they dont just go away or fade easily. retin-a actually i think is a very good product already when it comes to strecth marks, try the palmers cocoa butter lotion, it has always beena great help too
