I don’t think I’ve ever seen someone do this IRL.
I’ve seen it, usually when its really hot, and always someone who is wearing make up to prevent smearing the makeup.

If I try to use a gym without a towel I end up flicking sweat everywhere and nobody wants that
Gym and exercise. Stops salty sweat dripping in to my eyes.
Not as gently as I think you are talking about, but I definitely use a towel to dab my brow regularly in the summers. I live on Texas, and spend plenty of time outdoors working in a woodshop. I don’t like sweat dripping all over my workpieces.
