Subsurface profile Problem Model turns white

Eleszar1

I came across a problem today,   i have a character and the problem is that the subsurface profile makes my model turn white when i look upon the model straight forward but when i look with my camera down to its feet the model turns back to its natural collor,   this happens when in the material option of the character is the subsurface profile on,  but not when its default lit,   what could cause this?
