Determining the type of acne you have usually requires a professional evaluation by a dermatologist. However, you can look for some general signs that may point to whether your acne is hormonal or bacterial. Hormonal acne often appears around the chin and jawline, may be cyclical with your menstrual cycle, and usually flares up during times of hormonal changes like puberty, menstruation, or pregnancy. Bacterial acne, on the other hand, is typically characterized by inflamed, pus-filled pimples and may be widespread across the face and body. It’s important to consult with a dermatologist for an accurate diagnosis and appropriate treatment plan.
