 Yeah, well, that's what you want to do. You want to put it on twice a day, rub it into thin, hairless skin. But DHEA is a hormone precursor for about 50 different hormones in the body. It serves as a base. And so DHEA, we make more and more of it from birth to about age 25, and then we begin to make about 2% less per year, which means by age 35 we're making half as much, or making 20% less.
