I would suggest that you stop using Replens as it contains Benzene which is a toxic chemical.
If you are using Replens for vaginal dryness
then you can try other herbal options instead.
The approach of treatment should be returning to the original condition. A normal vagina is not dry. It is well lubricated. Vaginal dryness is a symptom of internal imbalance. Treating the symptom will not cure the disease.
Help your body lubricate the vagina instead of doing it yourself.
Drink more water. 5 LTR of water is ideal for daily consumption.
Avoid water just before a meal. It dilutes the digestive juices and retards digestion.
Try yoga for female reproductive system
Vaginal dryness can be caused by stress
is an ideal treatment for it.

This might solve your problem permanently. However for Prakrati based treatment consult an Ayurvedic physician personally.
