Hi Michelle. I hadn't heard of Blissel specifically, had to look it up.
Me, I have to use moisturisers several times a day, I have a few different kinds. Do you use anything else in conjunction with the Blissel? It doesn't look as if it has oestrogen in it.
Also, those of us with this issue generally benefit from topical oestrogen cream (Ovestin) or the Vagifem pessaries. The amount of oestrogen is so tiny that it doesn't cause issues, but does make the area more comfortable.
