The scientific world of 2016 is broken. Dozens of studies have proven that diet has a profound impact on acne, yet the American Academy of Dermatology’s official position is that diet has no effect on acne. A terrible position that will shame them for at least 100 years, once all of the evidence is out.
Yet even greater proof of the dysfunction of academia is that publicly funded studies are not freely available. Abstracts are online, but the studies themselves are hidden behind paywalls. I personally do not enjoy paying $40 to read a study, but it is important to this site for me to keep up on the latest research.
Luckily, there is another method. Most studies have found their way online in one format or another. All you have to do is grab a long string of text from the abstract, Google it (including quotes around the string), and most of the time you will be able to find a pdf of the study sitting elsewhere on the web.
I spent thousands of dollars before finding this technique, but now I use it every time. I hope it works for you as well.
