My two cents are the following : avoid irritation as much as you can. This means doing as few passes as you can, if possible shaving somewhat less often, and/or shave less close to the skin, for exemple using an electric trimmer. You should wash beforehand using hot water, and afterwards using cold water, and then dry before moisturising. I personally use and beeswax and olive oil based cream but a lot of products will do the trick. Remember that every skin is different, and sometimes, you can do everything right and still have symptoms, so you should adjust your shaving habits to accommodate those

Yes, and as someone who is probably close to a 5yo’s knowledge on the topic, I don’t know anything (or close to that) on either programming or other parts of being “tech savvy”. Thus me saying that coming on the ELI5 community and saying “yeah I actually want a very much not 5yo answer type” is not the spirit, I’d much rather like first basic answers, and eventually other comments going more in-depth, like we see in the majority of posts here

I meant the precision that OP already has knowledge in the domain and asks for more in depth elements

I’m sorry but doesn’t this go against this community’s concept of providing simple explanations for things?
