Unsure how it was a rant, or how it was incorrect?
Adding more detail to a female character's nose does make her look older. Adding more detail to a male character's nose also makes him look older.
Generally guides on drawing comics, like say the classic, "How to Draw Comics The Marvel Way" by Stan Lee will tell artists that if they want a female character to look attractive, you should give them a smaller, less defined nose.
...Which is a characteristic that makes them look younger. Yes, on average, cis women might have slightly smaller noses, and a lighter facial structure than cis men... but our noses and ears do still grow over time, just as men's do. Women with small, and not strongly defined noses are considered attractive for the same reason as blonde women, women with wide eyes, women with full lips and without wrinkles, women with perky boobs... it looks youthful. It's more acceptable for a male face to be a bit older-looking and craggier in the media, as evidenced by...well... Hollywood casting and also how we draw comic characters.
Hollywood actresses playing love interest characters are, on average, and we have pretty clear, concrete statistics for this, considerably younger than the leading man in any given production, to the extent it's not unheard of for women to play the mother of a man who is actually around their own age or sometimes older than them.
There are a lot of socioeconomic reasons for this. It's historically been more acceptable for an older man to marry a younger woman, for example, because men have a wider window for fertility and more opportunity to have things other than fertility going for them (like money and power)... It's a whole mess, but the upshot is this idea that youth is a much more important asset for a woman in terms of being attractive than it has historically been for a man. Of course, there's now evolution of that (not necessarily all for the better) and we see a lot of men getting treatment to prevent hair loss, or loss or virility, or even getting botox and plastic surgery.
But at the end of the day, my point is... older women have big ol' noses just like older men and older enbies. We all end up with a bigger nose than we started with (except the book version of Tyrion Lannister, I guess...) and some of us even start out with a big nose to begin with, and it's a shame that people can't just appreciate the beauty in that.
