Clubman Mend is a really good salicylic acid gel.
I'm prone to ingrowers, just because I get really hot really quickly and my skin kinda goes mushy after shaving, especially with any kind of moisturising agent in whatever products I'm using. Keep it really simple - low ingredient count soap, rinse well after shaving and enjoy a hot and then cold water splash. Simple witch hazel, if necessary, otherwise don't bother with aftershave which can irritate.
Switching to single pass and shaving every day worked out well for me. Take your time, really concentrate and make that single pass perfect. Be disciplined not to polish.
