After 12 weeks (i.e. at Visit 3), the following rules will apply for the second 12- week phase of the study:
* In case of resolution of the symptom (the dryness single score is equal to zero), the patient will suspend treatment and will undergo follow-up visits;
* In case of the single score is reduced but still greater than zero: the subject will receive Hyalo Gyn® open-label.
* In case the dryness gets worse the subject can choose whether receive Hyalo Gyn® gel open-label or undergo the follow-up visits. Patients will be allowed to use only water-based lubricants, not containing HA, hormones, or isoflavones, if necessary, only when engaging in sexual activity and specifying the reason for its use (multiple choice answer).
