This is one person's perspective. You can't generalize the system as a whole based on one person's experience.
When I walk around downtown Toronto, (Eaton Centre, Bay Street, Dundas Square) for example and when I ride the TTC, I look at a lot of people, usually women because I want to see what style of make-up is trending right now, (fashion magazines vs real world). And what I see is that most women 25+ wear minimal make-up. Late teens to early 20's they wear make-up with emphasis on the eyes such as several layers of mascara. younger teens, they tend to wear liquid liner with minimal mascara. Foundation is minimal on everyone, on some women that I see that are wearing full coverage, I can see that they are covering up visible blemishes.
To sum it up, it's mostly emphasis on the eyes and everything else is down played, I also don't see a lot of inspiration from fashion magazines and each woman has their own style. Also their hair is usually styled casually like in a loose/messed chignon usually secured by a claw clip, some with large hair pins, surprisingly not too many ponytails, then again this is winter.
So what I see is not so much make-up oppression, but as personal choice of expression. However, I am always expecting to see make-ups that are inspired from current fashion editorials, yet I don't, not even on different ethnicities.
