Love based on looks alone is doomed to failure, because good looks fade with time. Love does not depend on looks.
You may be confusing love with attraction. But even attraction occurs by things other than looks. It may be because the person is very witty, or kind or some other attribute. So, love and even attraction, does not depend on looks, good or otherwise.
True love comes from a shared life and shared values, not superficial things such as appearance.
