Acne is a common skin condition that occurs when hair follicles become clogged with oil and dead skin cells. Acne is caused by: ● Overproduction of oil - When the skin's sebaceous glands produce too much oil, the hair follicles become clogged and acne develops. ● Environmental factors - Acne commonly develops due to exposure to various environmental factors, such as pollution or humidity. ● Bacteria - Propionibacterium acnes is a type of bacteria that lives on the skin and can cause acne. ● Hormonal fluctuations - During puberty, pregnancy, and menstruation, fluctuations in hormone levels can increase oil production and cause or worsen acne. ● Diet - According to several studies, dairy products and foods high in refined sugars can cause acne outbreaks. ● Genetics - Since acne often runs in families, there can be a genetic component to its occurrence. ● Certain medications - Certain medications, such as steroids and birth control pills, can cause acne as a side effect.
