answer:I don’t know all the answers to your questions in the details sections, but YES, woman absolutely tried to enhance their eyes and lips before the 1990’s. Surely you’ve seen a movie set before the ‘90’s- notice all the lipstick, lip liner, and glosses? All designed to make the lips fuller. Same with mascara and liner. Advances have allowed women not helped much by cosmetics to experience the enhancements as well. See the wiki for mascara, and I’ve read that Cleopatra used coal to enhance her eyelashes. I am also willing to bet that the only people with “fake” lips you notice are the ones who have had it poorly or overly done, not the many, many women who look great with slightly fuller lips. The mouth’s lips can be compared to vaginal lips- some men and women think it’s attractive for both sets of lips to look engorged.
