I don't know who they are, but honestly (and no offense to any teen posters on here)...
When I think back to my high school days and experience with makeup...I'd rather go to a professional who has been an MUA for 5+ years than a 17 year old for advice. That and I don't know how much somebody who is still in the midst of puberty would know about skin care and such, or deal with the worries about budgeting for various tiers of makeup. (At that age, you either can't afford anything...or your parents are footing the bill for everything.)
Maybe that's just me since "back in my day..." high school was the first time people started experimenting with makeup and just learning how to use it and what it was, which means...there is no way in hell I'd ever ask my 17 year old self advice on make up...
(I suppose if you're 14 though, that the 17 year old is a genius?)
