I use "udderly smooth", which is another cow's udder cream. I only tend to use it at night, but it definitely helps my poor finger to heal faster!
If I'm having a really bad day and am poking my finger more than I'd like then I use the " new skin" liquid plaster. It does help to protect it, but with every prick it starts getting loose, so I don't always use it, as it can be a bit of a pain to use!
I haven't done my hexies for a little while so my finger is looking all fresh again, but I know that it's going to go straight back to its horrible state as soon as I start up again!
