Her trouble is not over
Remember how the heroine couldn't make out with the male lead because of all those silicon implanted area on her body? For the rest of her life she will have to cope with this situation. She will always have to worry about the silicon in her breasts leaking out, she won't be able to let her bf grab her butt for fear of messing up the implant there, she won't be able to enjoy passionate kisses because that might dislocate her nose implant. She went through all those plastic surgeries for love, but in the end she became incapable of consummating that love.
The above is the pathetic price she has to pay for her artificial gorgeousness, and it's not funny at all! That's why I don't think this movie is conveying the message that plastic surgery will solve all your problems!
