The science behind your acne breakouts


Today’s Video of the Day comes from the American Chemical Society’s Reactions series and takes a look at the science behind acne.

The three main factors involved in acne are bacteria, oil, and skin. More specifically, P. acnes is the bacteria typically responsible for your breakouts, while sebum is the oil that controls the amount of water that gets in and out of your skin.

When the body produces too much sebum, it causes a blockage in your hair follicles. As a result, oil and dead skin cells begin to accumulate, which feeds the growth of P. acnes. The buildup of sebum, dead skin cells, and P. acnes triggers an immune system response that sends blood to the the follicle, which turns the area red.

Next, white blood cells are dispersed to destroy the bacteria. But after they die, they add to the growing mess of bacteria and oil, leaving a red exterior with a circular whitehead in the middle.
