Relationship between acne vulgaris and diet

I was hoping if someone can offer any advice or suggestions on who to consult regarding acne that is primarily caused to diet.

I had a hypothesis that acne condition was related to my diet, so I decided to conduct an experiment on myself. For six weeks, I didn't control my dietary habits (i.e my meals contained moderate to high amounts of sugar, carbohydrates, and dairy products) and the result was that my face got oilier, acne got progressively worse, and no amount of superficial skin treatment regimen had any effect on my condition. For the next six weeks, I eliminated processed sugar, carbohydrates, dairy products from my diet, and there was a significant improvement in my condition. I didn't have new breakouts and saw some moderate improvements in reducing acne scars by using over-the-counter skin creams.

This seems consistent based on my research so far, there is seems to be a direct relationship as well. Here are some of the articles for reference:

It might be worth mentioning that my family doesn't have any history of chronic diabetes or sugar problems.

I would really appreciate it if anyone can point me in the direction of any specialists in and around the twin cities area who work with skin and diet-related issues.
