The compact sanitary panty liners are easy to use and are popular among women.
Compostable panty liners are supposed to be beneficial to health, but they can also cause diseases, because the vagina of healthy women has a self-purifying effect. It contains several aspects:
The vaginal epithelium of mature women will periodically thicken under the action of ovarian hormones, and the surface cells will keratinize and fall off, which is not conducive to the reproduction of pathogenic bacteria;
The glycogen stored in the cell produces lactic acid under the decomposition of the normal vaginal flora, so that the vagina maintains a certain acidic environment, which is not conducive to the growth of basophilic bacteria;
The mucus in the cervix is alkaline, which inhibits the growth of acidophilic bacteria.
Therefore, although the vagina is not sterile, under normal circumstances, due to a variety of factors, they can survive and be restricted in the vagina and become a normal flora without causing disease.
Therefore, the sanitary panty liners should be changed frequently, preferably in two hours.
