Now that's a fact! The cosmetic industry is said to be beginning to see booming business ( I've heard) as a larger portion of the population in the 1st world countries starts to age so there soon may be more interest in more in-depth research. I believe that the greater interest may also have to do with people in 1st world countries living significantly longer and wanting to make the most of the extended time so larger companies my be more willing to put some effort into the research.

It's just a guess of course.
