Acne, pimples, spots or zits can occur on anyone’s skin, regardless of ethnicity, sex, or age.
Acne is a skin condition in which the pores of the skin get clogged up with excessive oil and occurs when sebum (the oily chemical) is unable to pass from inside the skin where the sebaceous gland is located to the skin layer and the skin pore becomes clogged or the skin cells themselves grow in abundance and clog the pore.
As the sebum cannot then exit the skin, dead skin cells begin to pile up and bacteria begins to start growing.
This mixture of bacteria, excessive skin cells, and sebum results in skin inflammation and tenderness.
Eventually, the clogged skin pore, or hair follicle, may burst and a mixture of bacteria, skin cells, and bacteria is released and exits the skin.
