Paraffin wax is a soft colorless wax that is solid at room temperature but softens when heated above 100 degrees F. It is used as a spa treatment to soften the skin on hands and feet. The warmth of the wax also increases blood flow and eases aches and pains.  The treatment involves dipping your hand or foot into a paraffin wax bath multiple times, covering it with a plastic bag or plastic wrap, then waiting 15 to 20 minutes to remove the wax.  The wax is a natural emollient that helps to soften and moisturize skin.
