is it rude to tell someone they had a glow up?

Question

Update:

it basically means they look better now lol

Answer 1

Yes, that's rude. It's the equivalent of saying, "You looked so much worse before."

Instead, it's fine to say they look good, without referencing how or why.

Answer 2

@Jamie: I think a glow up is basically a make-over.

Answer 3

Not if you had good reasons for saying it  - whatever a glow up is . okay thank you Matt , yes I think that is rude and insulting  unless it was siblings or between loved ones .
