Didn't look at it till now but apparently the people who make that lip plumper posted about how Ayu uses it a while back, lol.

IMO, she doesn't need plumpers like this. She looks great in the pic though... that hair!

If anyone was wondering, this is the black dress Ayu wore. It's like a hoodie parka maxi dress that Ayu wore a bit... differently. She really makes it look a lot more luxe.
