I fly long haul with nothing on my face but Caudalie Vinoperfect serum and Embryolisse moisturizer. The only makeup I use is some eyebrow pencil because my brows have started to thin (thank you, menopause). I used to wear some eyeliner but I'd end up with raccoon eyes and decided it was better to just skip it but I throw some on if I need to look presentable when I disembark.

The more I see responses in favor of sans makeup, the more I am feeling comfortable with it. I checked the mirror at the end of the day and there isn't much left anyway. I may keep the mascara on, it never smudges anyway and just a little pressed power foundation before landing.

Longhaul, I usually remove my makeup shortly after eating. I always have a travel size packet of makeup wipes with me - I really like the the Ole Henriksen ones in the orange package. I think they're called "On the Glow". They smell delicious, like orange/vanilla.

Part of my falling-asleep routine (and self-care for my skin on those long flights) involves using a single-use moisturizing sheet mask. I'll get a cognac or a brandy, apply the mask, and watch part of a movie until it's time to remove the mask. (I always bring an empty ziplock bag so I can easily collect and dispose of any trash related to my personal grooming.) Then, sleep.

Upon waking, I apply a light tinted moisurizer and a quick smudge of eyeliner. Takes less than a minute, so I don't feel like I'm hogging the bathroom. I'm sure I've done this at my seat before, but since I have to use the toilet and want to brush my teeth, I'll be in the bathroom anyway.

If I have a long enough layover to go to the lounge, I'll often do a full-face, then.

I thought about a mask but they can be really messy. Also a bit scary.

I have my eyelashes and eyebrows dyed. I have pale skin, brows, and lashes. With dyed lashes and brows, I don't wake up looking like a ghost.

I also use eyedrops 2 -4 times a day and don't have to worry about mascara messes.

Tinted moisturizer and a nice moisturizing lipstick are all I need.

I'll confess, I've gotten a few interesting looks! Funniest was when I was flying with my boss, who was very startled when he walked past me en route to the toilet. Interestingly, nearly every time I do a sheet mask, a flight attendant makes a comment along the lines of "That's such a good idea" or winds up telling me her favorite kind of sheet mask. I try to be as unobtrusive as I can, and usually most people don't even notice.

The mask can be messy but I have it down to a routine, now, and the ziplock bag helps, too. It helps if you can put a paper towel or something similar on your chest, to catch any drips. I have extremely dry skin so this routine really helps.

I do not remove my makeup before or during flying overnight. Toward the end of the flight, either at my seat or in the lav I freshen up my lipstick and pressed powder foundation. As soon as I check in my hotel, I take a bath and redo my face and hair after that.

I recently switched to using Foreo, which is a little device that attaches a piece of mask (you buy them separately). I use those inflight for an intense hydration boost because it only takes 90 seconds for 1 round (you can do 2 for each mask, since there is a lot of leftover essence). It solved the "weird woman with a white sheet on her face" problem for me

The device itself was a little costly, but I managed to fit a great deal at my local duty free before one of my flights and grabbed it.

I always brush my teeth and take my makeup off in the air before "bedtime". I apply eye cream the heavy moisturizer that I use at night at home. Maintaining my routine cues my body that it is time for sleep and helps me to relax.

I say either do it while in the seat (who cares what people think!) or wait until you land to use the airport restroom. And/or if you have access to a lounge, they might have a private restroom.

I've seen women apply makeup on plane at end of overnight flight. I'm totally okay with that. Other option would be to use airport restroom after flight.
I kind of get grossed out in the airplane restrooms and minimize my time in them.
