The French made U225 is the most sophisticated mesotherapy injector currently available on the market. This mesogun is one of the most popular mesotherapy guns available. It is fully automatic, powered by pneumatic pressure generated by an air compressor. The U225 has two basic modes of function which allow continuous injection, intermittent injection a raffale and point-par-point. In the intermittent mode, the user can vary the injection frequency from 1 every 3 seconds to 300 per minute. This versatility can practically satisfy any technique. The rate of injection is also easily adjustable.
