Acne is mostly caused by two reasons. One is because the skin is oily and the sebaceous glands are overly developed and sebum is produced excessively. If the pores are blocked or if the oil is not drained properly because of other reasons, then the sebaceous glands continue to secrete and the sebum accumulates in the pores, protrudes and becomes acne. Another reason is that the hormonal imbalance in the body makes the skin grow acne. This cause is more common at the time of puberty. You should also pay attention to your diet in your daily life. The actual fact is that you will not be able to get a good deal on your own.
