Sween Medical Grade Dry Lubricant Body Powder. Non caking body powder used in hospitals to dry skin and reduce friction. We recommend its use as a dry lubricant while pubic shaving. Sween powder virtually eliminates any sticking between the shaver's foil and the skin, allowing the foil to glide smoothly over the skin. Simply shake a SMALL amount on to the area to be shaved, spread with hand and shave.
