Will this get rid of my acne? Or would this make it worse? Could it be the problem?

So i go to a chiropractor once a month and i have pretty bad acne...not awful...just below my mouth and on my cheeks..its always red and not really have a lot of big pimples but a lot of reddness. I'm 16 year old male by the way. And so i went to the chiropractor and he said that i should take one drop of iodine, 2 vitamin d, and 2 fish oil pills every day and he said he gaurenteed that my acne would get better within a month. Well, its been a month and there is little change to my acne. Im really getting sick of it. I am not unhealthy so its not the food, i workout and get excersise a lot, i am not stressed, i dont know what it is anymore. I wash my face almost 4 times a day and it seems to do nothing at all. Do you think it is because i wash my face so much? Could that possibly be the answer? I dont want to try that and not wash my face for a day cause i feel like more acne would appear the next day. But is there any way that that could be my problem? Cause i have no idea anymore what i can do to make my acne go away. PLeseee help
