What race are the people saying that women age poorly talking about?
Some women age well. A large part depends on your genetics, but women tend to look after their skin more also.
Interestingly though men age better than women in general. The reason is because men and women have different skin types. Men have thicker skin and much more collagen in their skin. It is the loss of collagen that makes the skin lose its elasticity. Men however, tend not to look after their skin as much as women so it isn't always readily noticeable.
That said Monica Bellucci is a good example of a woman who aged well. She said once that she felt she was at her most attractive at around 38-39 years of age. She certainly wasn't unattractive at that age, that's for sure.
If you've seen the movie irreversible, she was 38-39 in that movie.
