Groundbreaking research may pave the way for an acne vaccine.

Scientists at the San Diego School of Medicine said the vaccine focuses on the bacterial enzyme that causes acne without affecting beneficial skin bacteria.

More than 70% of people develop acne at some point in their lifetime – most often during their teenage years.

There are several factors that cause acne, including genetics and the environment.

One of the researchers tells the NBC affiliate in San Diego the vaccine might be available in five to 10 years.
