Zeno acne treatment devices--called an Acne Clearing Device--are designed for the home treatment of mild to moderate inflammatory acne. Zeno hand-held devices use heat energy to zap the bacteria that cause acne and pimple breakouts. Zeno applies a precisely controlled heat dose directly to the pimple through a metal pad. One Zeno treatment lasts 2½ minutes. Two to three treatments are spread over 24 hours. Zeno is developed and marketed by Tyrell, Inc.
