"Clinical data show a dramatic infection-fi ghting effect within one day of restoring the balance of bacteria on the skin," says Dr. Gallo. "How long those bacteria will last probably depends on the individual patient, and we're still learning about that." (The data was published in Sci- ence Translational Medicine, February 2017). CoNS-based topicals are not yet commercially available, but Dr. Gallo believes they may reach the market within a year. "First, we're going for disease treatment," he says. "But there are obvious applications for normal skin with limitations from aging and photodamage that can be im- mediately translated."
