Red light has anti-inflammatory and antiseptic effects and can promote wound repair, but it is difficult to kill the mold completely with red light alone. It is better to take medication for mycosis vaginitis and red light treatment may be more effective. Mycosis vaginalis is characterized by thick, tofu-like leucorrhea, itching of the vulva and vagina, and even ulceration of the vulva and vagina in severe cases, so effective treatment needs to be given in a timely manner. In this case, systemic medication can be given orally with fluconazole tablets, 150mg/tonic, or vaginally with clotrimazole pessary, 1 time/day for 7-10 days. In addition, red light can also be used for treatment, but red light treatment can play an auxiliary therapeutic role, the effect of red light alone to kill the mold is relatively slow, so mycosis vaginalis can be treated by a combination of treatment. In addition, it is prone to recurrence. After treatment, routine review of the leucorrhoea should be carried out to understand the treatment of vaginitis and consolidate the treatment for a course if necessary.
