Zeno is the world's first FDA-cleared acne device for home use. It is a small, cell phone-sized device that is rechargeable. The tip delivers a precisely controlled, low-level dose of heat to an individual acne blemish. This heat causes destruction of the bacteria within the lesion, which results in the reduction of inflammation and resolution. This improvement of the acne pimple can usually be seen within 24 - 48 hours after treatment. This device is appropriate for mild to moderate acne. It is not a cure, but is excellent for the treatment of individual pimples.Zeno is backed by a 30-day satisfaction guarantee. Zeno is available for $200.00 plus tax. Replacement heads available for $35.00
