I don’t really shave much, mainly because I enjoy having facial hair. The other possibility might be that I look 16 or so without it, I guess we’ll never really know.
What I actually do is that I trim my beard along my cheeks and on my neck to keep things neat and tidy. The issue is that when I do shave, I use both a razor and a portable electric trimmer. The trimmer is to shape my beard and the razor is to make sure everything is smooth. This causes razor burn. If you’ve shaved, you’ll know that razor burn is annoyingly uncomfortable as your skin is quite sensitive.
