Like if Rihanna or Bey use bleaching products, that's not self-hate, IMO. They were light to begin with and light skin ppl do get uneven skintone. I speak from personal experience.
Nose jobs depend on how far you go. Patti Labelle is a good example. Her nose still looks negroid. Just more symmetrical to her facial features. Someone like MJ had self-hate issues and his many nose jobs is proof of this. etc. ec.
but someone like Azealia and Lil Kim obviously don't like what they see. They could've maintained their skin color. Same with Charlamagne. Their skin tones look like they have an illness.
