Acne can be caused by various factors, including hormones and bacteria. Determining whether your acne is hormonal or bacterial can be complex, and it often requires a professional assessment. Hormonal acne is typically linked to fluctuations in hormone levels, especially during puberty, menstruation, pregnancy, or menopause. Bacterial acne, on the other hand, is often caused by an overgrowth of acne-causing bacteria (Propionibacterium acnes) in the pores. It’s important to consult a dermatologist for an accurate diagnosis and appropriate treatment.
