IHere are some other things you can do–if you are not already doing them. These are the things I have noticed help me as I have been plagued by pimples for such a long time. When I stray from this diet the pimples come on even now in my late 40s.

Drink lots of water as this will help remove toxins from your system via the kidneys rather than the skin. I think the standard computation is your body weight divided by 2 and that will give you the number of ounces you should drink a day. Of course, if you exercise a lot or live in a hot climate you will need to add more water to your total intake. Some of your water will come from vegetables and fruits and these are also excellent sources of the vitamins in your supplements. Plus fresh raw vegetables and fruits contain enzymes that help your body to assimilate other nutrients. Avoid coffee and black teas and sodas as they are diuretics. Non-caffeine (herbal) teas are okay as well as fruit juices, but the best body cleansing drink is pure water.

Avoid sugar and sugary drinks. Not only can sugar cause pimples in some people, the metabolism of it robs the body of important nutrients, for example calcium, which is also necessary for skin health.

Dairy can cause some people to have acne, while it doesn't bother others. You might experiment to see if avoiding dairy clears up your acne.

Salt can trigger acne in some people. I have heard mixed information on chocolate. When I was a teenager everyone said chocolate caused pimples so I gave it up with no results. But when I gave up sugar, my face cleared up quite a bit.

I think the most important thing is eating lots of fresh fruits and vegetables. A standard approach is at any meal: 20% carbs in the form of whole grains, 20% protein and 60% vegetables. This is called the body ecology diet. So if you look at your plate you'll see that the vegetables dominate, taking up 60% of the surface of what you would normally eat. Veges should be fresh and/or very lightly cooked. Instead of smothering salads in commercial salad dressings which almost always contain loads of sugar, make a simple lemon and olive oil dressing. Eat fruits between meals for a snack instead of candy or other high carb/high caloric treats.

Other things I have heard is that often people will have pimples as a result of constipation. I think this makes sense in terms of hydration. If you don't drink enough water to flush toxins out through the kidneys the body will flush out through the skin. Also, if there isn't enough water available for the metabolic processes, the body starts reabsorbing water from the feces, which means that the elimination aspects of our body aren't as efficient. So being hydrated will help tremendously.
