My husband has Vitiligo and he was told his doctor that it is also caused by a vitamin E deficiency. I've never heard that before. Can anyone confirm or deny this?

I have never heard it is caused by vitamin e deficiency.
I do know that it is caused by an autoimmune reaction in your body. That is when the immune system is supposed to protect itself it turns against its own body and attacks.
No one knows what caused the immune system to act this way. It may be genetic.

Also, I have vitiligo and several other skin type diseases caused by the immune system. One is Lichen planus. I would love to get rid of these diseases.

You need to make sure that you moisturize your skin so that your chances for wrinkles are lower at a young age. As we get older you will definitely get wrinkles. The only thing that we can do is to try and slow down the process and minimize the damage.
