Which is the Bacteria that Causes Acne?

Propionibacterium acnes is the bacteria that lives within the oily pore of the hair follicle. It possesses the power to aggravate the response to the growth of the acne to severity, and cause red and swollen bumps on the skin.

Acne, as we know, is a skin condition that results in whiteheads, pimples, cysts, blackheads, and nodules. Although not dangerous, acne does leave scars. The pores present in the skin help in maintaining good health by bringing out the dead cells through the oil developed by the oil glands. Acne occurs when there is a blockage of the pores.

However, according to research, the frequency and occurrence of the acne are due to the strain of the bacteria. It means that not all bacteria living on the skin are responsible for causing acne.

Apart from the Propionibacterium bacteria, the other factors that support the growth of acne or are responsible for the development include:

  1. Hormonal change where there is an excessive increase in the androgen level within the body, which happens during the puberty period.
  2. Use of medicines that contain lithium and androgen, which are prone to trigger Propionibacterium bacteria.
  3. Use of cosmetics, as they contain greasy ingredients that stop the oil from removing the dead skin cells.
  4. Emotional stress too has its share of effect on adding acne, as there is an excessive secretion by oil glands under such a scenario.
  5. Females, especially teenagers, experience acne during their menstruation period.
