Vaginal itching has a number of causes.
If you are postmenopausal, a common cause is vaginal dryness due to reduced estrogen.
NeuEve balm cream is good for menopause related vaginal dryness and itching. If it did not help you much, your itching could have other causes, like allergy, skin condition, yeast, BV, etc.
This article provide some good answers:
The most effective method to manage your inching is to identify the hidden cause behind it. Once the cause is known, you can manage it accordingly.
Other common causes are allergy to irritants (like contact dermatitis), skin condition (like eczema, psoriasis, lichen sclerosus that can cause redness and itching in the genital region), yeast, and BV.
You can rule out yeast by using the over the counter antifungal Monistat-3. If it works, you may have yeast. But if it does not relieve your itching, you may have another cause.
BV often has fishy odor. You can diagnose it yourself. Using NeuEve Silver or Gold can clear it.
If you cannot figure our what causes your itching by yourself, I suggest that you visit an Ob/Gyn or skin doctor to have a check up.
