How does Pretty Feet & Hands RSR work so well?

Pretty Feet & Hands Rough Skin Remover is a nonabrasive cosmetic containing water, oil, paraffin, a light fragrance and preservative. It is designed to apply a layer of wax and other solids to the skin as a smooth emulsion. Subsequent rubbing causes evaporation of moisture, thereby breaking the emulsion and precipitating the waxy solids on the skin. Continued rubbing to dryness causes a scrubbing and lifting action by the particles of paraffin due to their adhesiveness.
