Good on you for trying different things out, and looking at the holistic approach.
Alternativista mentioned stress reduction - have you looked any techniques for doing that? Things like EFT really helped me. I know The Love Vitamin has great articles on it, and I'm posting some on my blog as well.
I noticed that my acne flared up alot when big life changes happened, like moving, getting a new job, and new life choices. You mentioned you had a serious breakout after in your senior year summer - were there any big life changes happening that could have been challenging?
Wow, congratulations! I saw an allergist and she mentioned the fight-or-flight response, and then linked that to stress and depression. I started doing biofeedback exercises, which to me seem a bit similar to yoga and meditation. How long did it take you to see results with EFT? I found some tutorials online - are there any online videos you'd recommend? Not sure which ones to follow. Also, did you change your diet or add any supplements to boost your immune system, or was EFT enough for you?
With acupuncture, after the first few sessions I noticed a huge reduction in stress and anxiety. It was very important to find the right acupuncturist - some didn't work for me, others were trying to adjust my hormones or cleanse my liver and gut and inadvertently worsened my acne. I found that the best acupuncture treatments are the mild ones - like, ones for stress & anxiety reduction, insomnia, blood building and strengthening the immune system. Sometimes the effects of a treatment can last up to 2 weeks, but if I don't keep up with it I don't notice any long term improvements. Sometimes the acupuncturist puts seeds on my ear lobes with pressure points (e.g. for sleep, stress, etc) so I can self-treat and that helps prolong the treatment by a few extra days. Have you tried acupuncture? I recently visited a new acupuncture place where they use high-tech gadgets, and the acupuncturist used a nice massager and a red light on my face. I noticed a big improvement in my skin within a few hours! It really makes a difference once you find a good practitioner.
I noticed two levels of improvement. On the physical level, my experience was much the same as yours - after using EFT on the acne symptoms, I would notice improvements right away; my acne would fade, the itchiness would go down, the redness would lessen. These improvements happened within a few hours, and lasted for several days.
On the longer term level, it took several months to for improvement in breakouts to show. I had experienced a lot of trauma as a kid, which was responsible for my depression. I used EFT on these childhood traumas, and that's when long-term improvements happened. This was a therapeutic kind of work, and involved a lot of rediscovery of who I was, and neutralizing the painful childhood memories.
Luckily, thanks to EFT, I did most of this work on my own relatively painlessly.
It took about a year for breakouts to stop entirely, but they did started lessening right away. And it only took this long because of how much I personally had to clear. The process sped up after I worked with an EFT practitioner and therapist, which was towards the end of the year.
I didn't change my diet (I had tried cutting out gluten and sugar at one point, which didn't help) or use any supplements. Partly because I was travelling, and didn't have access to the same supply in other countries. EFT was enough for me.
I haven't tried acupuncture, but I certainly want to at some point. Finding the right person to work with really does make all the difference. Even after I was working with an EFT practitioner, I used EFT between sessions to hold on the to the progress we had made together - which is one thing I like about EFT; how easy it is to do it on yourself.
As far as resources, this guy has some really good videos for explaining the basic technique.
