Women must not have double eyelid surgery or other similar cosmetic surgery during menstruation. Although cutting double eyelid surgery is only a minor operation, it is still a traumatic or invasive medical technique. Plastic surgery is performed on people's eyes, and women must never do plastic surgery similar to cutting double eyelids during menstruation.

The plastic surgeon explained: Under normal circumstances, blood clots should form on the wound surface soon after plastic surgery. However, due to the increase of plasminogen precursor activator in women's blood during menstruation, it can destroy the blood clot on the wound after cosmetic surgery, causing bleeding or prolonged bleeding time, thus causing wound infection in the case of pathogen invasion. Coagulated fibrin and hemolyzed plasminogen precursor activator exist in human blood. Only when these two substances are in balance can human blood flow normally. However, during menstruation, due to the large increase of precursor activator in blood and uterus, women can cause periodic uterine bleeding.

Experts suggest that women can have cosmetic surgery three days before menstruation or three days after menstruation stops. If it is carried out during menstrual period, take effective antibacterial drugs. However, for the sake of beauty seekers' own health and surgical effect, double eyelid surgery is still not recommended during menstruation.
