In terms of women's special physiological cycle, there are always a few days every month that are most beneficial to girls' breast enhancement, because these days women secrete the most estrogen hormones, and they secrete them in equal amounts for 24 hours. They are the eleventh day after menstruation, the twelfth day, the thirteenth day and so on. These days, women's ovarian activity is very active, and the function of estrogen synthesis and secretion is very strong. Therefore, girls who are eager for breast enhancement should effectively grasp the special period of these days. Starting from seven days after menstruation is clean, they can eat more foods such as papaya, potatoes and tomatoes that are helpful for the secretion of estrogen hormones.
