It is not possible to answer this question in general but it must be answered on an individual basis, best with the help of a medical professional. Every woman has a natural vaginal smell, that can change with her menstrual cycle. This is perfectly normal and nothing to worry about. But to feel more fresh in the intimate are, a special mild cleanser can be used, e.g. Vagisan Intimate Wash Lotion. The lotion cleanses gently the external intimate area and can be used on a daily basis as it is very well tolerated.
