You're not the only one who's still battling breakouts.
About 50 million Americans are diagnosed with acne every year, according to acne specialist Dr. Joshua Zeichner. However, there's no cure for the skin condition because scientists and doctors haven't determined the exact cause of it-- yet.
Doctors know acne is caused, in part, by P. acnes bacteria, which we have our entire life. The bacteria is good for us in some ways, but scientists are creating a vaccine that can block the negative acne-causing effects of P. acnes without killing the bacteria itself.
Doctors will soon begin testing the vaccine on patients during clinical trials.
