Estrogen prevents a decrease in skin collagen. In addition, estrogen maintains skin moisture by increasing acid mucopolysaccharides and hyaluronic acid in the skin and possibly maintaining stratum corneum barrier function.
缺乏estrogen会怎样呢？第一就是发胖，原因如下：Estrogen receptors located in the hypothalamus serve as a master switch to control food intake, energy expenditure and body fat distribution. When these receptors are destroyed, the animals immediately begin to eat more food, burn less energy and pack on pounds.第二就是会骨质疏松。
那是不是ML越多约好呐？不是，Estrogen太多会诱发乳腺癌，endometrial cancer （子宫内膜癌）等。
