To "billnotgatez", thanks for the reply but I was asking if there are any forum on the internet where students of cosmetology collaborate, I wasn't asking anyone on how to make a cosmetic. I have read the forum rules fully, I don't think asking whether such a forum exist will break any rules of this forum.
Also, "jusfying use of some ingredients" doesn't mean I will hurt myself trying to make a cosmetic. It means that I want to know whether an ingredient in the formula of product X was a good choice and why. For example, Gillette uses HEC in most of their shaving products, I would ask (I am not asking here) why Gillette prefers HEC and not HPMC.
In a nutshell, I am looking a forum dedicated to cosmetology students who will discuss among themselves the curricular topics. I have no intention of posting anything in this forum that breaks the forum rule. I did search for such a forum, one I found appears to contain many professional chemists. So, I was looking if any member of this forum knows any forum suited to my needs.
