I also found that my diet has a huge impact on my skin. It seems that every time I drink ANY dairy, it is inevitable that the next day I develop those deep red cysts that don't come to the surface without a lot of work. However, lately I have aimed to completely cut out dairy and lowered my sugar intake and the results have been pretty good, but not perfect. I use a retin-a and bp combination and it seems to work really well, but even with the two, I still found that any small hiccups in my diet when I accidentally consumed dairy or too much sugar would result in bumps.
So, I decided to dig further, I believed that acne could be cured through internal methods and so I did some research and experimentation. I've tried pretty much every natural supplement you can imagine to see if they helped my acne - you name it: zinc, alpha lipoic acid, vitamin b5, fish oil, etc. None of them seemed to have any dramatic impact on my skin, except for the fish oil pills, which actually seemed to have a very negative effect on my skin - I would break out after every time I took them. So, when my friend mentioned that cod liver oil worked well for him I was a little bit skeptical, because it seemed from my experimenting that omega-3 oils seemed to cause break outs for me.
But, after working so hard to get near-perfect skin and then having it all blow up on me, literally, after one night of drinking and eating a very small amount of dairy, I decided to try it out of desperation. WOW! Right after taking it I didn't get any new bumps whatsoever and after 3-4 days I could feel/see an immediate difference in my skin. After a week, I had perfect skin, and I mean absolutely perfect. I couldn't believe how smooth and glowing my skin looked and felt. Now, I admit that the bp and retin-a has a huge impact on the speed at which my skin recovered from the small lesions, but nonetheless it was a dramatic improvement. Apparently, if you have bad skin it is very possible that you have a vitamin A and D deficiency and the most readily digestible form of these vitamins is contained in cod liver oil. Also, a deficiency of vitamin D leads to the retention of phosphorous in the kidneys and there is a relationship to proper kidney functioning and healthy skin.
I should also note that along with the cod liver oil, I started to take an apple cider vinegar supplement - in pill form. From what I've read about ACV it is also a very important factor in preventing acne from forming. If you read the acne.org reviews on ACV you can see that they are all mostly very positive. Now, I think a lot of people believe that it works topically, but I have not needed to try that method yet. I believe that the internal route works just as well as the topical version because the most important consideration to healthy skin is to maintain a low pH mantle on our skin. By ingesting the ACV it will give our blood this very important pH level which will in effect help to control the skin's pH levels as well. Without the proper acid mantle, the skin is open for all kinds of bacteria and infections - aka acne. If I do happen to ever break out again, I will without any hesitation consider using ACV as a topical in combination with my other products to ensure perfection.
So far, I've gone a very long time without any minor breakouts other than a few ingrown hairs from shaving and a blackhead or two. I am saving money on products because I now use less of the harsher topicals and overall my natural supplements are very inexpensive. You can purchase the ACV for very cheap - I think I spend $7 a month for 90 pills (3 a day). The cod liver oil is also relatively inexpensive ($20-30 bottle that lasts 3 months); however, it is very important to note that you can not skimp out on the quality of cod liver oil. If cod liver oil doesn't undertake the proper filtration processing you can have an impure product that is very high in mercury, which is toxic to the body. So, do some research and make sure you CLO is of the highest quality - I use Nordic Natural's CLO (orange flavored). Now I don't have to use as much BP or retin-A and my skin is starting to restore it's natural look and all the old red marks have completely disappeared.
I would have to say that if you have moderate acne that I would recommend getting on retin-A and using a very small amount. It really helps to restore your skins natural look, reduces fine-lines/wrinkles, and clears away red marks, but make sure that when summer comes you wear proper SPF. Hopefully, Dan will have released his SPF by then because I have never had a positive experience with any market SPF - but that's another story all together.
Seriously, if you're on Dan's regimen (or not) try out the CLO/ACV combination, it seems to be a godsend for me so far. Good Luck!
I have attached an interesting blog link about internal acne cures that I think sums up most of what I said. Although, not all of what is mentioned in the blog is completely necessary to healthy skin, I think I have nailed the key components.
