I had already taken supplements for a while a few months ago, it was called Azinc Optimal, pills with a lot of good stuff in it but it didn't change my EC at all, objectively.
Yes I also used Mupiderm, anti-bacterial ointment, also asked my GP to provide me anti-fungal ointment. As we don't have to use it for an extended period I've actually stopped using it.
Currently I'm just using whatever cream, honestly they all do the same, I have a myriad of creams next to me.
