What is one of the common causes of hormonal acne in women?

Hormonal acne in women is often related to fluctuations in hormone levels, particularly androgens such as testosterone. When testosterone levels increase, it can stimulate the sebaceous glands in the skin to produce more sebum, which is the oily substance that can clog pores and lead to acne formation. This process often occurs during certain times in a woman's menstrual cycle, menopause, or due to hormonal imbalances. Increased testosterone levels can also be linked to conditions such as polycystic ovary syndrome (PCOS), which is known to contribute to hormonal acne.

The other options do not directly relate to the specific hormonal changes that trigger acne. Excessive hydration might help maintain skin health but does not influence hormonal levels. Low carbohydrate intake can affect insulin levels but is less directly linked to hormonal acne compared to testosterone fluctuations. Daily exercise is beneficial for overall health and may help with hormone balance, but it is not a primary cause of hormonal acne.
