A weirdly phrased Alcohol Question

I go to college, and obviously college kids drink (whether they're allowed to by law or not yet). I myself personally don't drink yet but will be when I turn 21. 
I have a question for my of age alcohol drinkers: which alcohols that you've have been easy on the skin side affects like acne (my friend (who is of age) got real bad acne after an afternoon of tailgating at a football game) and bloating, as well as quick hangover tricks to help reduce the affect of said hangover. 
This is a really random question but my friends think I'm an alcohol affects expert since I was in a medical degree program before I switched to Education (a very drastic switch I know) so I want to know what to tell them
