Why are unscented after-shave so uncommon, most of after-shave I can find at a reasonable price have that typical cheap cologne smell which is going to wreck any perfume you wear.
But when looking in most shop, most of them still have some fragance in-it and often, so looks like that people shaving their face buy-it
I have used cold water, followed by an alum block, then cold water again after I let the alum sit on my skin. Then I just apply unscented noncomedogenuc lotion. I usually use Neutrogena ultra gentle daily facial moisturizer.
