What Causes Acne

Acne is one of the most common skin conditions, affecting people of all ages, particularly teenagers and young adults. It develops when hair follicles become clogged with oil, dead skin cells, and bacteria. Although acne is often associated with puberty, it can occur at any stage of life.

One of the primary causes of acne is excess sebum production. Sebum is a natural oil produced by the sebaceous glands to keep the skin moisturized. However, when these glands produce too much oil, it can mix with dead skin cells and block pores, creating an environment where acne can develop.

Hormonal changes also play a significant role. During puberty, menstruation, pregnancy, or periods of stress, hormonal fluctuations can increase oil production, making the skin more prone to breakouts. Additionally, the bacterium Cutibacterium acnes, which naturally lives on the skin, can multiply inside clogged pores and contribute to inflammation.

Other factors may worsen acne, including certain skincare products, excessive sweating, friction from clothing, and some medications. Genetics can also influence whether someone is more likely to experience acne.

Although diet is not the direct cause of acne, some research suggests that high-glycemic foods and certain dairy products may worsen symptoms in some individuals.

Understanding what causes acne is the first step toward managing it effectively. With a consistent skincare routine, appropriate treatments, and professional guidance when needed, acne can often be controlled and its long-term effects minimized.
