In reply to probablylost:
I have used anti-hydral once, but it was not an ideal situation, as my skin on the affected finger was wafer thin and I was heading to Font the next day! It did not (not unsurprisingly!) help.
I think the best approach is to apply it to good skin a few days before a trip where you will climb loads for numerous days in a row. I was told by someone who uses it and loves it to take care!
I bought some Rhino repair last autumn and have not really used it much yet. Seems more like a moisturizer, and seems to have pretty healthy ingredients which would do little harm, but also not sure it is exactly an equivalent to anti-hydral, but I know others swear by it, so I will probably give it a try on my two Font trips this year (leaving tomorrow morning 😀)
Edit - I have just discovered that there is a range of Rhino products and I seem to have the repair cream. Tom Randall has produced a short video raving about the range which sounds more like a substitute to anti-hydral.
