I know a few people that have acne which is not pleasant. A special chocolate that could help treat acne was reported last year, now it's the turn of a more gadget like solution, the Zeno.
Zeno is advertised as the new secret weapon in the war against pimples. It stimulates a heat-shock response in p. acnes, the bacteria causing at least 90% of all acne blemishes. Heat shock proteins, activated by bacterial cells under heat stress, cause the self-destruction of p. acnes within the lesion, reducing inflammation and allowing the skin to return to a healthy state.
