One thing that I really don't like about many Mexican women is the amount of make up they use, especially around the eyes. I understand that the social pressure to be beautiful is rather strong, but looking like a raccoon won't improve your chances of finding the man of your dreams, really. You're more beautiful if you accept who you are and smile (there's nothing more beautiful than a woman smiling) than if you end up looking like a sunburned geisha.
Long life to those with subdued make up!
