Ever Heard of Skin Whitening Injection?

I was asked by a friend to share with her this thing called Skin Whitening Injection. She told me it cost RM300 for 10 bottles and it actually come in a set of 20 bottles. So, my friend decided to share half with me. She was told by a friend of her that this injection can be done at her friend's home where there will be someone else doing the treatment. I was a bit worry we got cheated because this injection normally will be done only by qualified dermatologists or professionals and what the heck her friend (non-qualified beauticians) is offering the service at home? Is such a big risk to do this treatment because they will straight inject the liquid into our body, better think twice before doing this treatment. So here are some of the goods and bad about skin whitening injection.
The ingredient of skin whitening injection are Vitamin C, Transamin and glutathione (GSH) which act as antioxidant for treating cancer and AIDS. Some side effects of skin whitening injection is nausea, vomiting, abdominal cramps, diarrhea and could lead to liver failure if overused. And without the right medical guidance, simple injections can possibly lead to allergic reactions which can sometimes be fatal.
My advice to all, better one consults his/her doctor before taking any glutathione supplement. For those of you who are planning to go under the needle, what is most important is to make sure that the people that you are turning to for these treatment are legitimate and licensed to practice the procedure.
