There is a slight difference between both. The major difference would be the size. Face epilators are usually smaller in size. The head of the epilators is also small. Since the hair present on the face is too small, it becomes difficult for the body epilators to remove them off. A face epilator which has a small head and tweezer is capable of removing them as well. All the process to be followed to reduce the pain and irritation remains the same apart from the design and size.
