Hi, I agree with you. I think that what you meant that if the engine in the car is not working, there is no point to fix the back mirror. If the problem is the skin you should see what is wrong with the skin, and not with the stomach. I tried many things for my vitiligo and still trying. About 3 weeks ago I started to use a herbal liquid called tevaskin. I see some results the skin started to become a bit more orange-brown. When the bottle will end I will think of buying another bottle or asking for the refund.
