What Causes Acne

Pressure From Helmets, Backpacks, Tight Clothing

If there is pressure against the skin, as is the case when wearing hats, and helmets, or when a backpack is pressing down against shoulders, then the potential for irritation and acne breakouts are real.

Either friction, as is true when someone is wearing tight clothing, or pressure as in the aforementioned hat or helmet, can go a long way towards affecting the pores and causing acne to flare up.

Environmental irritants

If a person works in a garage or in a factory, certain chemicals present in such environments can actually cause acne flare-ups, if not lead to its appearance.

Oils, for instance, when brought in contact with skin over a long period can clog up pores, or at least irritate the skin. Pollution can have much the same effect upon the skin, clogging pores and creating infections

Heavy Scrubbing of Skin

Picking or squeezing blackheads and/or whiteheads can cause the infection to move deeper into the skin and which will lead to scarring.

Diet

While no foods actually have been linked to the cause of acne, it is proven that certain foods can be responsible for acne flare-ups.
