What is a common cause of adult acne?

Hormonal changes are indeed a common cause of adult acne. In adults, fluctuations in hormones, such as those experienced during menstruation, pregnancy, or periods of high stress, can lead to increased oil production in the skin. This excess oil can clog pores, leading to the development of acne. Additionally, conditions such as polycystic ovary syndrome (PCOS) can also contribute to hormonal imbalances that result in acne in adult women.

While dietary choices, environmental factors, and improper skin care can influence the presence or severity of acne, hormonal changes are often the primary underlying trigger for adult acne, particularly in women. These hormonal influences can create a sensitivity in the sebaceous glands, causing them to produce more sebum, which in turn contributes significantly to acne formation.
