Why do you have acne on your forehead?

Acne medicine is called acne vulgaris. The first cause of acne vulgaris is the relatively strong secretion of androgens during adolescence. The strong secretion of androgens brings several major problems. First, the pores of the hair follicles begin to become thick. Second, love to produce oil. No oil, no acne. Because people who love to produce oil, the sebaceous glands of the hair follicles are particularly prone to blockage. After blockage, sebum accumulates in the sebaceous glands of the hair follicles, and acne easily develops. Why do you rarely get acne on your arms? But on your forehead? Because the forehead is the position of hormones, it is easy to cause more secretion of oil, so there are often people who say that it is easy to grow acne in the T part, especially in the forehead, nose and chin. These are also places where hair follicle sebaceous glands are secreted very vigorously. The secretion is more, the distribution is more, and the oil is loved. Acne, acne.
