Determining whether your acne is hormonal or bacterial requires a careful examination of your specific symptoms and history. Hormonal acne is often characterized by breakouts around the jawline and chin, and may flare up around the time of the menstrual cycle. Bacterial acne, on the other hand, is typically associated with inflamed, pus-filled pimples and may appear on various parts of the face and body. Both hormonal and bacterial acne can coexist as well. It is recommended to consult with a dermatologist for an accurate diagnosis and personalized treatment plan.
