Undecided Question

Which one should I go w/ to sell? "Avon" or "Mary Kay"?

Both cosmetic lines are popular and I want to makemore of an internet business out of it though. Which one should I sell though?? I'm really interested in wanting to come out w/ my own anti-aging skin care line, right now going to an institute for esthetics to get the background but also for more experience and to make some extra money, I was considering Avon but then was thinking of Mary Kay as well? Which is a better buy or sell I should say?
