Sweetorange, I think it depends on what causes your acne. It can be an allergic reaction or sensitivity, inflammation, bacteria, digestion, hormones... They can be impacted by diet, but it might not do any difference either. Is diet the only thing you want to concentrate on? 

Have skin care solutions not worked for you? Some non costly tips.. if the acne is due to bacteria you might want to try to skip foaming cleansers. Foreign bacteria does not normally live long on our skin, but a foaming cleanser it is going to make your skin more alkaline, and more susceptible to bacteria. If hormones, exfoliation can be helpful, and oil control products. If it is due to inflammation, be sure to protect against the sun with a sunblock, and read the labels on every product you use on your skin, google the ingredients and check if they could be contributing. And so on.

A few quick and easy digestion tips! Sit down and dont stress when you eat. Do not dilute stomach acid by drinking with meals. And let your digestive system rest between meals.

What have you tried so far?

Sorry for ignoring your main topic   To add to the answer above, I would say also to avoid getting more toxins into your body. It detoxes continually, so eat organic where you can afford it, let the fresh air in, clean up dust. I do not mean to be too obvious. But sometimes we just need a reminder  Sweating, and even crying, are very good detoxes. And of course stress managing is a good one. Emotional states have a big impact on the toxicity of our bodies!

Hello!

Well, I didn't have acne during my puberty and I have always had a good skin complexion. I'm very fair, so I just had the "problem" of getting sunburnt in summer hehe. But my complexion has changed since 2014, when my stress increased a lot (Law School can be tough sometimes) , I started suffering insomnia and of course, eating more sugars and junk food .
Three weeks ago I made an appointment with my dermatologist , I was very fed up of having like cystic acne you know? So she explained me due to stress, lack of sleep, bad diet and right now being depressive , all together, messed up my skin ( I don't have just acne, psoriaris and eccemas are the other "side effect" of my levels of stress too , especially when I have so much work to do in the office) . She gave me a topical med called "Tretinoin" which is making a good effect but leaves my skin very very dry . But it works. Anyway, I think I must change my diet because eating chocolate every single day (and not just a section, I mean the whole bar lol) I think it's a bad idea lol.

I do need to control my stress ... I think. I was wondering if yoga would help me to manage my emotions way better...
