I can't stand when women cake their face with makeup, it spells a bad sign that something isn't right. I'm all for women feeling comfortable in their body, but to me, I feel too much makeup looks worse in some cases.
In this case, I would feel it's pretty deceptive. I view it similarly to some trans people not admitting they're trans. Like, be honest, don't hide who you are, because it could cause trouble later on. I view it the same way as if someone edited a photo to look better.
Personally though, I like when women don't wear a ton of makeup, and honestly some women look better to me without makeup. I like to see the real person, that way I know whether I will be for sure attracted to that person or not.
Also, doesn't makeup damage the skin with prolonged use? If she wears makeup often, maybe it's causing issues with her skin.
