Our shavers and trimmers are meant to be used on dry skin and hair and should also be free of oil. Baby powder MUST be used to achieve best results. The powder will absorb skin and hair oils that you did not even know were there as well as acting as a lubricant. The powder will also improve the quality of the shave you get.
