How does the Zeno work?
Precisely controlled heat applied for a specific period of time causes the bacteria that cause skin lesions to self-destruct through a heat shock response. When the bacteria die, the pimple goes away. The proprietary Zeno technology triggers a heat shock response that destroys bacteria and allows the skin to return to a healthy, normal state.

How many treatments does it take?
2 to 3 2½-minute treatments spread over twenty-four hours are sufficient for most pimples. Often, only one treatment is needed.

When should Zeno be used?
Use Zeno at the first sign of a pimple. It works best when used on a pimple in the early stages of development. Also, the sooner pimples are cleared up, the less chance they have to leave scars.

How does Zeno compare with topical or oral treatments?
Zeno can clear up a pimple in just hours. Most other medications can take days or even weeks to work. What's more, other than slight, temporary skin redness, Zeno has none of the side effects described by most topical or oral medications.

Is Zeno safe and painless?
Patients included in our clinical trials experienced little reaction to the low-level heat. Other than some temporary skin redness following a treatment cycle, no other adverse side effects were reported. Should you experience any discomfort when using Zeno, discontinue use and consult your skin care professional.
