When does Becker Nevus stop developing?

Hi there, I have a Becker nevus on my right shoulder and back. The back is darker but the front has more hairgrowth. I’m now 21, I think the mark has stayed the same for the last couple of years but I’m not entirely sure.
Has anyone’s mark grown larger or darker after puberty? I know it gets darker when exposed to UV light, but I hope it doesn’t expand on it’s own.
