Needle-free injectors use CO2 or compressed air to propel a microjet of liquid six times smaller than a 30-gauge needle through the skin. Instead of feeling the piercing pain of the needle, the patient only feels a slight pressure as the propelled liquid passes through the skin. These are the only low pressure needle-free devices in the world. Through the aid of this revolutionary technology, Needleless supports and aids doctors and skincare professionals in taking the next step in their pursuit of performing the most effective and exclusive procedures ranging from aesthetics to medical administration.
