Hi - sorry I haven't heard of Neogyn. Are you in the U.S. as it appears to be an American product. Personally, I use an oestrogen cream twice a week (prescribed by my doctor), so that is similar to your Vagifem, and on the other days I use 'Yes' water-based vaginal moisturiser (mainly underneath) and that works for me. Hope you get some answers about Neogyn!
