Zeno and Zeno's Hot spot are two different devices from the Zeno Corporation for skin treatment. Zeno happens to be a device that has a head attached to it through which it produces heat. The heat is set beforehand, and the battery is used to run the device. There is a DIP controller chip that is fitted to the device; this helps to control and modulate the temperature so that it can be suitable for all kinds of skin.

It is usually used to fight the outbreak occasionally, and it uses the patented clear point technology of the company. The only usage of the Zeno hot spot is effective enough to treat and eliminate infection on the skin. The amazing thing about it is that it gives a result within 24 hours.
