Acne is caused by a combination of factors, including:
- Hormonal changes: During puberty, increased hormone levels can lead to the overproduction of oil in the skin, leading to clogged pores and the development of pimples. Hormonal changes during the menstrual cycle, pregnancy, and menopause can also cause acne.
- Bacteria: The bacterium Propionibacterium acnes (P. acnes) is commonly found on the skin and can contribute to acne breakouts by increasing inflammation in clogged pores.
- Hair follicles: When hair follicles become clogged with oil and dead skin cells, they can form pimples and other types of acne.
- Genetics: There is a genetic component to acne, and some people are more prone to acne breakouts than others.
- Stress: Stress can trigger an increase in hormones that can contribute to acne breakouts.
- Medications: Certain medications, including corticosteroids, testosterone, and lithium, can cause acne.
- Diet: While diet does not cause acne, some studies suggest that a diet high in sugar and dairy products may make acne worse for some people.
- Skin care products: Some skin care products, including oils and heavy creams, can contribute to acne breakouts by clogging pores.
It is important to note that acne is a complex condition that can be influenced by a combination of factors. Treatment will vary depending on the individual and the severity of their acne.
