Addressing the original question "what helps your extremely oily skin" I would have to say diet and exercise. Using topical treatments certainly helps and will make a difference in your skin, but it will be in vain, if you don't also address the problem from internally. I've noticed that my face has gotten significantly less oily when I cut out sugar and complex carbohydrates from my diet. For the first couple of weeks I didn't notice anything, but I stuck with it, and soon I noticed my face was drier, less inflamed, and I had less pimples. Another huge part of clearing up my skin and reducing oiliness was running. I am not sure of the science behind this, but I've noticed when I run for longer than 90 min my face clears up for the next couple of days. Maybe its because of the constant sweating or the insulin control or whatever it might be, but exercise makes a difference. So to sum it up, have a good face/skin regiment, eat healthy, and exercise. Like 'life' in general, there is no magic pill, anything worth having is worth working for.
Addressing the claim about scientific fact vs anecdotal claims: Anecdotal claims cannot be entirely refuted just because the science doesn't support it or hasn't been proven yet. The field of science whether it be dermatology, physics, quantum mechanics, etc is constantly changing and being revised. Only a couple of years ago did we discover that more than 50% of our body is made up of microorganisms and bacteria that are not our own. The implications of this discovery has caused so many different fields to re-evaluate what they know about the human body and how it functions. What kind of impact do you think that had on the field of dermatology? Do you think that within those couple of years that we now know everything about the human skin and how it functions? Anecdotes are an essential part to the scientific method; they are the starting point for hypothesis' and help direct scientists in trying to explain why an anecdote might just be a rare result, or if there is actually some repeatable result. Regardless of the outcome, claiming that anecdotes are completely useless goes against all that is science and the pursuit to understanding our natural world.
This sounds exactly the same as to what I have. White pastules that appear only on my face and no where else. For me they occur on my chin and upper lip and around the creases of my nose. I only started to develop this issue about a year ago and am not sure what the cause of it is. What I have learned through trial and error, is that if I exercise regularly it will go away. While I was training for a marathon all of my folliculitis cleared up and remained clear for about half a year. As soon as I stopped running it came back. Why this is...I am not sure. I then took an allergy test to see if what I was eating was causing it. I discovered that I'm mildly allergic to quite a few different foods and in general my IGE was pretty high, so I changed my diet to exclude all those foods. For a couple of weeks I was clear of folliculits, but as soon as I ate any of the foods that I was allergic to it came back. It wasn't quite as severe as before, but it was back again.
I guess what I'm trying to say is, I feel your pain. I'm going to keep experimenting and seeing what works and what doesn't work in clearing up my folliculitis, and I'll let you know if I find anything.
