5-4.Factor that acne can done:Hormone
	There are three mechanisms that maintain the activity of each organ of man's body.
	The movement of the material of hormone, making, the movement of of "Internal secretion system" and the mental status and the body, and relations to senses of the sight and the sense of touch, etc. keep the condition to health by this "Immunity system" and 3, and adjust driving out the foreign body and the bacillus that entered from "Nervous system" and outside of the body. The hormone is a material that is made from special internal organs (internal gland) in vivo, and discharged into the blood stream. The hormone discharged into the blood stream arrives at an organ and a cell far away through the blood stream, and adjusts the working.
	（Male hormone） Male hormone secretion accelerate→Sebum gland activation ●If the secretion of the male hormone does accelerate, it becomes easy to be able to do acne. The function of the hair gland is activated, and the male hormone is made easy not to recover by it not only makes to the skin to be able to do acne easily but also depraving the symptom.
	（Female hormone） Ovum hormone secretion decrease→Sebum secretion control decrease ●The follicular hormone has working that controls the secretion of the sebum contrary to the male hormone. The secretion of the follicular hormone also has time when acne can be done easily according to the menstrual cycle with the ovary function because it is deeply related.If the ovary doesn't work neatly, it becomes easy to be able to do acne by the secretion's of the follicular hormone decreasing. Progestin secretion accelerate→Sebum gland activation ●The progestin is secreted from the corpora lutea of the ovary. There are a pregnancy and implications, and is an action that improves the secretion of the sebum just like the male hormone at the menstrual cycle.
	（Adrenocortical hormone） ●It is one of the adrenocortical hormones secreted from the adrenal cortex on the kidney. It is a character hormone, and it has the action that develops glands such as ovaries and the testicles, and it has an influence big as for the hair gland, too.
	（Neurohypophysial hormone） ●The pituitary body that exists in a hypothalamus is a center organ that secretes various hormones. There is a character of secondarily especially increasing "Gonadotrophin" and "Adrenocortical hormone" by respectively increasing. The amount of the sebum increases, too, when mutual hormonal secretions become active.
	●In the follicular hormone and the progestin of the male hormone and the female hormone, it is these character hormones that it is related to the character function. It these is character hormone and adrenocortical hormone that it is personally related to the secretion and the control of the sebum. The sebum gland function is to invite activation by secreting each tropic hormone such as the adrenal cortexes and gonads if it says for the activity of the neurohypophysial hormone.
