Different types of acne can be caused by various factors, including hormones and bacteria. Hormonal acne is usually associated with hormonal fluctuations, such as during puberty, menstrual cycles, or pregnancy. It often appears on the lower face, jawline, and neck. Bacterial acne, on the other hand, is caused by the overgrowth of acne-causing bacteria on the skin. This type of acne usually presents as small, red, inflamed bumps and can appear anywhere on the face or body. It’s essential to consult with a dermatologist for a proper diagnosis and treatment plan tailored to your specific acne type.
