Seeing as how this challenge has been around since at least 2014, I think the "no lashes" is a bit outdated and like Skell so eloquently wrote, "it don't make no sense to say 'no lashes' but other genetical stuff is okey-dokey". I worked with one young lady that got so stressed her eye lashes fell out. That is my only personal experience in RL of someone having no lashes.
No brows? Sure all the time, just please draw them on so they match.
I also think challenges like these should be open to interpretation. Bare to me means more than just taking off make-up or clothes, it is exposed and a little vulnerable. There's a bit of my pixel soul (so to speak) in that shot.
