Braun Beard Trimmer Do You Have To Use Pre And After Shave When Just Trimming The Beard?

Do you have to use pre and after shave when just trimming the beard? - braun beard trimmer

I am young and new to the whole shaving thing. I know that, to use when you shave before and after shaving, but what happens when you cut your beard?

I have a Braun Cruzer 4, which is excellent for the style of beard, the beard I'm having a length cut very short (probably the length of the hair so that a few millimeters) on the face. Is it necessary, before and after shaving or something else?

Thank you for your time
