Hi, I used tenovate GN cream for 8-10 years only for the purpose of brightening the face skin and it was working too. After I stopped using that I got reddish face and itching. I went and consulted doctor and used those medicines and my skin became normal now. I am using aloe derm cream now, if I apply that my skin n becomes very very dry. And my is skin is very black and I want to get little bright skin, my friend suggested me to use cosglo gel. Can I use it? Or it also has the side effects? And how long I should use it? Please reply.
