I think most men especially in ice dance user powder for the face and lipstick
especially with the bright lights to add texture to the face at it usually washes the face out
I would have expected they all wear some make-up, but not splatter it on like they're clowns or going out at Halloween. Maybe foundation and contouring to even out skin tones, a bit of eyeliner, and some lipstick. Like it or not, they are almost always being filmed in competition / exhibition and they understand that they need to visually prepare as if they are on a TV or film set. Features wash out, so they may need some so that eyes, lips and noses stand out a bit more once they add all that harsh lighting. To what degree each uses make-up depends on what each skater wants to emphasize. I'm sure they have consultants to test and guide them, and experiment to see what works best from presentation point of view.
Let's also not forget: they're on a sheet of ice. Combined with the lighting of the camera that is a LOT of white space showing up on camera. They would something to make their faces stand out. Expression would be more obvious to the judges and would add to the presentation aspect. If I were a judge and let's say for example Yuzu was on the other end of the ice, I would not be able to see him emote as clearly, but if I see the face with just the right make-up, it would stand out in the instant I saw it when he intended to in that moment, and would be more inclined to give a better mark.
Some skaters I understand also take acting classes. With what they learn to express themselves in their faces, (some) make-up can help them stand out for sure and make it more obvious to a judge or spectator.
I wonder, with all that sweat pouring at the end of each skate if we can look at the close-ups in the K&C area, can we see what they've been using?
I'd be surprised if any elite skaters (in the last three groups or so) don't wear some makeup, especially for televized competitions. Spotlights don't do anyone's natural skin tones (regardless of ethnic/racial background) any favors.
In the Johnny Weir documentary, "Pop Star On Ice," his friend Paris said something to the effect of: people made a big deal about Johnny wearing makeup, but all male skaters do for competitions.
But mascara and eyeliner like Weir or Sandhu? I think not. Because mascara and eyeliners are so obvious the camera couldn't miss it.
Close up in the top men face like PChan, Ten, Javi or Hanyu show no track of mascara or eyeliners. I am not sure if they use lipstick or not, their lips look pale, though.
Powder? Maybe. But since they are all sweaty it's so difficult to tell.
