Corhale, just seen your post.
Dermovate is fine if it has been prescribed for this area, but it is unwise to self-treat if you have not been examined for other conditions besides VA (eg, lichen sclerosis, dermatitis etc). GPs will not necessarily be able to recognise these, so you could ask for a referral or see one privately.
Good resources for VA are Jane Lewis's private Vaginal Atrophy Facebook group, and you can follow her on Instagram @my_menopausal_vagina, where there are many useful posts and videos. She is Maryjane on here.
