Massive breakouts on the forehead are usually acne, and are directly related to the secretion of sebaceous glands, abnormal levels of the patient’s own hormones, or poor lifestyle habits. Abnormal secretion of sebaceous gland cells will lead to exuberant oil secretion, thus triggering the clogging of forehead pores and the appearance of acne. When mental irritability causes endocrine imbalance, which leads to hormonal imbalance in the body’s secretion, the increased secretion of androgens can further aggravate the clogging of hair follicles and pores, causing acne. Acne can also be caused by poor diet or lifestyle habits, such as consuming spicy and irritating foods for a long period of time or staying up late at night. When acne occurs, it is recommended to go to the hospital in time to identify the cause of the disease, under the guidance of the doctor to treat the symptoms, to do a good job of local care, pay attention to personal hygiene, eating habits, avoid scratching.
