My number-one travel beauty tip? Hydration.
When I fly, I try to avoid wearing any makeup at all (sometimes I’ll cave and put on a little mascara, but that’s it). As evidence: here I am an hour before departing for the airport. Glamorous, no?
Moisturizing is the key to arriving at your destination looking like you’ve just returned home from a vacation, rather than looking like you’re in desperate need of one. I load as much oil-free moisturizer as possible onto my face, neck, and hands, and make sure to drink water every time the beverage cart comes around (and, OK, maybe the occasional Bloody Mary as well…because passing out for a couple of hours is also key to arriving looking refreshed, and I find some in-flight alcohol facilitates that process).
