Hello Lou Lou and welcome to the forum. You may find a moisturiser such as Yes helpful. This can be used as much as you wish to. I have not used Vagisil but I am sure other members who have will reply to your post.
Just to say, when VA is severe, twice a week is often not enough to help it. I personally have to use treatment every day. When I miss a day I am very sore.
A tip I have learned is to wash in emollient. Apply emollient to the vulva before a shower, wash it off in the shower and reapply to act as a barrier. I also switched from baths to showers to avoid prolonged contact with water.
Apologies if you knew this already. I just thought I would mention it if not.
