Free Spray is a great way to create a numbed effect on areas that are about to be pierced or tattooed. It works by delivering an ice cold blast, numbing sensation. It is especially suitable for cartridge piercing which can sometimes be more painful. It is suitable for use anywhere on the body except for internal areas such as the nasal passage, genitals and inside the mouth. All that you need to do is spray on the area a few seconds before the piercing or tattoo commences and the areas should feel instant cool and numb. Freeze spray is a solvent that evaporates at room temperature and works by spraying onto the skin and drawing out all the heat. It essentially freezes the tissue. It can be uncomfortable when first applied but should provide a cooling effect immediately after.
