What causes acne?
Acne happens when the oil glands (pores) in the skin become blocked. Hormones make the oil glands produce more oil (sebum) and if the pores are blocked, a build-up occurs and you’ve got acne.
The face, neck, chest, shoulders and upper back are the areas mainly affected by acne because they have the highest number of oil glands.
Acne usually starts at puberty when increased levels of hormones (known as androgens) cause an increase in the size and oil production of glands.
If you have a family history of acne, it may also increase your chances of developing acne.
What happens under your skin before a pimple pops up?
If the pore becomes blocked, oil builds up and causes irritation. Bacteria rapidly multiply within these blocked follicles contributing to the redness, swelling and tenderness of pimples.
