Decoding the Science: Which Bacteria Triggers Acne?

Acne and pimples can hamper your confidence and put you under emotional stress. The key to treating acne breakouts is finding out the reason behind it. Once you identify you have bacterial acne, you will have to find the right method of treating it. Scroll through this article to understand more about bacterial acne and how to get rid of them.

Introduction to acne and the role of bacteria

People with oily skin experience a higher amount of sebum production in the body. As dust, dirt, and grime block the pores, bacteria get trapped below the skin layers. This triggers acne breakouts on the skin.

Types of bacteria that can cause acne

Primarily, researchers have found a key type of acne causing bacteria. If you are wondering ‘acne is caused by which bacteria’, Propionibacterium is often considered to be a primary reason. This type of bacteria is usually present in the skin pores.

It thrives on sebum as an energy source. As a result, it engages the body in an immune response that causes inflammation.

Propionibacterium thrives on the skin without causing any harm. Therefore, people with and without acne have this bacteria on their skin. This type of bacteria, along with other commensal bacteria, helps keep your skin healthy.

But, in certain environments, this bacteria can cause acne. Typically, it will trigger acne in the presence of excess sebum. But, this type of bacteria is not contagious and does not travel from one person to another to spread acne breakouts.

Treatments for bacterial acne

The professional treatment methods available for curing bacterial acne are as follows:

  • Phototherapy and Laser Therapy: Light-based therapies, including laser or blue light treatments, can reduce inflammation by targeting the bacteria that cause pimples.
  • Chemical Peels: Chemical peels involve using acids to exfoliate the uppermost layer of the skin. It helps in unclogging pores so that the number of acne lesions minimises.
  • Microdermabrasion: People with mild bacterial acne can benefit from microdermabrasion. It involves gently exfoliating the surface of the skin to get rid of dead cells on the skin. As a result, it also clears up blocked pores and reduces inflammation.
