I think there are guys out there who probably do have sensitive skin or skin with problems or certain characteristics that just physically actually feel better when they use something that helps their condition.
Not knowing actual numbers and just going on a gut feeling, I'd bet that those guys with actual issues are far fewer than people who buy the stuff not because they need it, but because they think alcohol kills their skin or is bad for them.
I know plenty of old codgers like myself that have used alcohol splashes their entire lives and have just amazing skin.
Sometimes it's just genetics, you know?
I own 200 vintage and modern aftershaves. They all have alcohol in them. I keep a bottle of Thayer’s Medicated witch hazel for the very rare rough shave, but it has alcohol in it also.
I can’t imagine using anything that would overly moisturize and make my face appear healthier or younger, for my wife has enough trouble keeping her hands off of me now.
