There’s a new acne vaccine in development. But even that, as promising as it is, may fall prey to many of the same pitfalls as current treatments.

The vaccine, which if put into use would be the first of its kind, is designed to reduce the body’s inflammatory response to the toxins secreted by bacteria in the skin. So far the vaccine has only been tested in mice and human-tissue samples, but “the potential impact of our findings is huge for the hundreds of millions of individuals suffering from acne,” said Chun-Ming Huang, one of the lead researchers working on the vaccine, in a press release.
