Though make-up only works "wonder" as long as there is a decent distance between the one, that looks at a person and the one, that wears it. Close-up views by daylight make any make-up lose its magic, so I wouldn't take that make-up-thingy about her lips too serious, as we've seen Ayu's face on many close-up photos from LA recently, and she seemed to wear barely any make-up, still her lips looked good. So whether its nature beauty or plastic surgery, I doubt make-up would do this to her.
You can see some concealer around her nose here, that's probably all, except of the eye n lip makeup:
