I know it's a really small (if not insignificant) thing, but it really bugs a part of me that the only way to permanently improve base beauty is the procedure at the laboratory. I wouldn't mind having a basic process to improving the stat similar to the mental stats that takes time and money while the lab procedure is the one time here and now boost.

I'm gonna level with you - I actually really like how the beauty mechanics play out. You have the lab procedure, or beauty potions (which last a long time) or clothing to affect it, so there's quite a bit of flexibility. But the fact that Beauty can only be changed to a point makes higher grade captures that much more valuable, because grade is what determines the base beauty. It doesn't matter if you're going to bust them down to Slave grade - if Beauty is important, you'll probably want to catch a Noble.
I get where you're coming from - so much else is malleable, and it's frustrating to be left to RNG for something that's sometimes critically important (I'm looking at you, Sweet Voiced Nereid). But in a way, I kinda like it.
