      I know, it sound so seductive. But it isn't true. The good genes theory has failed miserably in recent high quality studies. I loved it too, but I bowed out. Beauty is l'art pour l'art.

      The study seems to only compare young women, so not compare older women's faces to younger woman's faces. Also, how do they rate attractiveness? The argument that younger woman would tend be healthier than older women seems plausible. Some diseases also obviously diminish beauty.

      Because age actually predicts fertility, although it is not genetic and not an interesting individual difference feature.

      But to gauge fertility (depending on age), you have to estimate age somehow. Beauty of faces could be useful in estimating age.

      From a theoretical point, it is only interesting if women of the same age, but different levels of beauty, differ in health or other good genes marker. Objective age is uninteresting, as it is completely environmental (date of birth). We want to know why is beauty so attractive.

      But beauty is an indicator of youth, and youth is attractive. In nature, people don't know each other's objective age, as there are no birth registries or even calendars. Maybe test how beauty correlates with age estimation?

      Well yes, but the exciting question is if beauty differences NOT linked to age are associated with fitness markers explaining the attractiveness.

      Statistically, though with wide variation, older age encompasses features (like wrinkles) that tend to reduce beauty, being linked to reduced fertility and attraction. But those are not the theoretically pertinent ones.
