What's the word or phrase used specifically to describe someone who is only concerned with physical appearence of others?

Question

I believe it starts with み and is something like 'only has an eye for beauty', but it's been a long time since I used it. I believe it's a kanji compound.

Answer 1

You're probably thinking of the word menkui (面食い).

Answer 2

If you're sure about み, it could be 見た目重視, or maybe some other phrase starting with 見た目.
