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.
Preventive Lifestyle
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.
Meditation is an ideal treatment for it.
