Whereas I appreciate the wealth of knowledge in this thread, I am a Guy, and have been using rubbing alcohol since I was 17. (I will be 40 in feb od 2014). Isopropyl alcohol is all I have ever used and my skin is great. I have never suffered from acne, nor have I ever had anything more then the occasional pimple. I will say that I do not use it every day, but I can comfortably say 3-4 times a week, sometimes twice a day in the summer. It may not be for everyone, I realize that, but to scare someone away from doing like that when some can do it and be just fine (again my skin is good after 23 years of usng alcohol) is not the best policy.
Thanks
