Beards are just a cultural and/or fashion thing.
As for skincare, whether or not you have acne or poor skin is mostly genetic and skincare only helps to a small extent. You get people who wash their faces and use 10 different products religiously with acne, and people who do nothing but shower with none. Anyway, that said, I don't think washing your face as a man is feminine at all, but going over the top and obsessing over it might be. Being overly fixated on one's appearance is generally a flaw women suffer more than men.
