Well, as a Clarins representative once told me, Asian skin is rich in melanin, so it can take more sunlight. Their skin is conditioned for their warm(er) climate. It also allows for aging more gracefully and why the skin is usually much softer than northern Europeans. So, I guess it kind of makes sense that they wouldn't need heavy moisturizers, because their skin is more naturally moisturized than those fair complected people of northern European descent.
I, for one, need a moisturizing cream because my skin is very sensitive and dry. I also happen to have a fair complexion.
I once chuckled at a DHC (Japanese skincare/cosmetics company) introduction in their catalog which stated something about since Asian women's skin was so much more delicate, they needed delicate cosmetics. Au contraire. Asian skin can take much more abuse. That's how they hold up so well. I would describe a fair complected redhead as having delicate skin.
