It is recommended to keep the vulva clean, and actively treat vaginal inflammation or vulvar inflammation, you can apply erythromycin ointment locally for treatment. However, if the vulvar skin turns white and appears to lose color, it is often caused by vulvar malnutrition. Clinically, it is often manifested as the appearance of small fissures on the vulva and vaginal atrophy. It is recommended to give active treatment, for example, you can use progesterone ointment and dermatophoresis to rub the vulva alternately, so that the local elasticity can be restored. If the medication is not good, surgical treatment is possible.
