Mostly I reach for a BodyShop one called "Mattifying day cream" made from seaweed, it is totally unscented and quite thin. If it is serious bit of razor burn I may then for for DR Harris Aftershave Milk or the Nivea ASB. Onbe of the really good ones is Tabac, it is incredibly highly scented, use the ASB and you will hardly need to use the aftershave.
I have tried many and of them all the best course is avoidance, if a soap makes your skin feel too dry try a different one, if it is burn try different techniques to get rid of it. Henk sem me a sample of his own ASB which was very like Nivea in consistency but works just as well as Dr Harris. Since then I am a WH followed by a splash shaver most days, an AS like DR Sandalwood I find quite moisturising anyway but if the skin is still a little tight or dry (or using cologne) then its any of the light moisturusers.
Thayers do a WH moisturiser which looks to be good value, these days it is not often I use ASB/Moiusurisers. It was antdad that suggested quitting the ASB's and it seemed to work for me, at first there is the desire to put some ASB on after shaving now it is the last thing I do. Just stick to WH and a Splash and leave it for some time to settle and then see how it is before I go out.
Experiment and have fun, it is the only way to know what will work for you.
