This gadget from CoolSense is an ingenious device. Kept in the freezer, then placed on the skin for a few seconds it reduces skin sensation by cooling the skin, enabling us to inject the skin without pain. It basically replaces the need to use local anaesthetic injections prior to prolotherapy and it works remarkably well. After use we clean the head with cavicide which thoroughly disinfects the unit.
