Hey guys, ive been coming to these forums looking for some advice for a while now. Only now that my breakouts have become a problem I cannot handle I needed to make a topic for some personal advice.

Ive been having acne for the better part of 8-9 years now (started around grade 10) and I am now 23 and still unable to control my breakouts. There have been periods of time in my life that it has been much clearer but it has always been there since i was about 14. Recently ive got a case of , well I really dont know what. I have basically no acne on my forehead, i do get a zit or two inbetween my eyebrows but other than that it is all on my chin/jawline/mouth area. Used to have bacne/chest acne a few years back and that has resolved besides blackheads on my chest. Ive been told hormones, diet, stress, etc are all causes of acne but recently I have changed my diet (no dairy , eating alot more vegetables and fruits than before, very conscious of foods that I know will not be good for my skin) and there is no beating these breakouts. I also have been trying a new face wash procedure, rinse with water in morning, toner, astringent, benzoyl peroxide,  after work shower and cleanse with carbolic soap, and same toner astringent benzoyl procedure, before bed i usually wash with carbolic soap again and the same procedure. I have been on this procedure for the 2 months or more and the acne is getting worse. And worse.. Is there something bigger to this problem? I went to a family doctor and he told me in his own words "you're doing everything you can" after I told him the products I was using. He then prescribed me a stronger benzoyl peroxide to use and a 2x daily pill and told me to see him again in 6 weeks. I'm now nearly half a week in and acne breaks out as i wake up, when I get off work, and before bed. Almost religiously my skin will break out once a day and I need to pop white pimples. 

ive changed my diet , almost no dairy, very little junk food, and mainly eat sandwiches  for lunch and then vegetables for dinner. I also work construction, which obviously is a dirty sweaty job and doesnt help my acne at all... After work I often see zits have already rose to the surface of my skin throughout the day. This is also my first out of town job - eating is proving to be much more difficult as I cannot cook like I would at home. Does eating less effect acne ? 

I take vitamin d everyday and Emergen-C vitamin supplement. Are there other vitamin supplements I should be trying ? 

just looking for any advice on why my breakouts would be occuring at this age, ive done this job for a couple years now and it did make my acne worse but not like this. Could it simply be hormonal?? I would consider myself an aggressive personality and ive often thought maybe a surplus of testosterone could be having an effect on my acne. Really any positice advice at this point would be appreciated. I understand acne is different for everyone and Im trying to figure out my solution.
