It's hard to say because this girl is such an entrepreneur! You gotta love her. L'oreal just dumped a B team onto her line. I'm sure the relaunch will be successful. As a product developer myself, I remember we totally screwed up our first skincare launch for the company I worked for. But we learned a lot and the 2nd launch - we we killed it.
I wouldn't change a thing - the learning curve was more valuable that my college education.
