Word that means "losing through becoming aware"

Solution 1:

I would say "Don't say this is beautiful because you will spoil it by exposing it".

[Merriam-Webster]

2a : to make known : bring to light

b : to exhibit for public veneration

PS You might also look at the notion of kennings. Unfortunately, I can't find the source right now, but I read somewhere that the point of kennings (that is, referring to a certain notion using a mild metaphor) was exactly not to let its features fade away by exposing them too much; if you call gold "gold" a hundred times, it will lose its shine, so a skald will always call gold "dragon's pillow" or something like that.
