Adult acne usually comes down to a mix of hormone fluctuation, genetics, and how an individual’s skin reacts to oil and inflammation — the same basic mechanics as teenage acne, just running on a different set of triggers.

Acne forms in and around hair follicles when oil, dead skin cells and bacteria combine to block a pore, producing blackheads, whiteheads, or inflamed red bumps.

Acne forms when a hair follicle gets blocked by a mix of excess oil (sebum) and dead skin cells, then a bacteria that normally lives on everyone’s skin multiplies inside that blockage and the body’s immune system reacts, causing redness, swelling, and sometimes a visible bump. That’s the short version. But almost every part of … Read more
