My sister used to take Amway's vitamin E, but later I saw that she also took Yangshengtang's vitamin E instead of Amway's, which probably felt similar, but Yangshengtang's should be cheaper, so she took Yangshengtang's.
But it is unrealistic to eat vitamin e to remove spots.
My parents and I both ate Amway, and I think it is still effective, but I took vitamin BCE at the earliest time, and my skin got better almost two months later.
This effect can't be seen for a short time, but it will take a long time to know.
