Society still expects me to look 25 and play up my features like big eyes, full lips and an hourglass figure as if that’s my only value to society.

Do you think you can set an example for your eligible daughter by letting yourself go? "Society" is doing you (and your daughters) the favor of "forcing" you to be a MILF so that those younger than you will have examples to follow.

The "as if" is syntactically and literally a counterfactual. Looking good is a good thing, but adult women are valued by "society" for all the things they do in every sphere in which they do them. The one does not denigrate the other.

And what if we’re skewing evolution by exaggerating our features? Having big eyes, full lips and an hourglass figure doesn’t guarantee someone will have “perfect” babies and will be a good mother.

I did say "statistically," but maybe your eye make-up obscured your vision. Evolution does make mistakes, and maybe women still using their looks to attract men is one of them. But "what if?" isn't enough. What it if rains frogs tomorrow? Odds are that the "what if" won't happen.

I’d argue that our society has evolved past the need for superficial mate choosing.

I would argue first that there is nothing "superficial" about the multiple traits exhibited by a woman who can and does appear beautiful. And I would argue second that your argument is elitist, that most women would like to feel pretty, even if those in your circle are not among them.
