My dad died before I reached puberty, so shaving has always been interesting. Lately I've been suffering razor burn while eliminating the omnipresent neckbeard so common among the nerd set.
Now I won't be a neckbeard, and I take a razor to it whenever I can, but it was seriously hurting after shaving. I shave in the shower as to make sure my face is wet for easier shaving, and less razor burn. After shaving, the neck area would turn red and hurt. I tried changing shaving creams, I tried changing razors.
So I bought some aftershave. The relief was near complete, no red neck, and no irritation.
Now the mustache line on the other hand, felt like a wound being sanitized with steel wool. golly it burns.
