Customer question:
What causes facial acne? Anonymous customer's question
Pharmacist's answer:
Human skin has pores that are endowed with oil glands under the skin. Follicles connect the glands to the pores. Follicles are tiny sacs that produce and secrete sebum. The glands produce an oily liquid called sebum. Sebum transports dead skin cells through the follicles to the skin's surface.
Acne occurs when pores become clogged, and oil accumulates under the skin. Skin cells, sebum, and hair can eventually stick together in a plug. This plug then becomes infected with bacteria and causes swelling. Acne begins to develop when this plug begins to break down.
Propionibacterium acnes (P. acnes) is the name of a bacterium that lives on the skin and contributes to the infection of acne. The severity and frequency of acne depend primarily on the strain of bacteria. However, genetic factors can also increase the risk of acne.
Other causes of acne include:
- certain drugs containing androgens, lithium
- comedogenic cosmetics
- hormonal changes
- emotional stress
- menstruation
Certain factors in your environment also contribute to acne or can worsen acne breakouts, including:
- stress that increases the hormone cortisol
- wearing tight-fitting clothing, masks, and headgear
- air pollution and certain weather conditions, exceptionally high humidity
- use of oily or greasy personal care products such as heavy lotions and creams
- working in an area where you are regularly in contact with grease, such as working in a restaurant with frying oil
