Savlon is indeed magic cream, and still works when you get older. I have recently rediscovered it.
As for the shaving, I am finding that really good moisturising is helping. I moisturisise twice a day, whether that be using nivea after shave balm or nivea moisturiser, it is really helping me get a better, more comfortable shave. I also use a bit of baby oil on my face just prior to lathering up, that also seems to help.
