Hi groove,
There have been a lot of great suggestions here. I will add one as well. I practice a style of qigong called Pan Gu Shengong. Basically, this is a Chinese way of absorbing energy to improve your health. Since I started practicing this qigong every day, my acne has mostly cleared up on both my face and my back. It is very efficient at improving skin problems. This happened with no change to my diet as well. This happened because the skin is regulated by the immune system. When your immune system is functioning better, your skin will show it. This qigong can be learned by correspondence, since it is very simple and safe to practice. It takes about 20 minutes per day to practice, and can be done anywhere at anytime. If you want more info, you can contact me, or go to

Another option similar to this is called Tong Ren. This is a way of energy healing using an acupuncture doll. I have not used it myself for skin problems, but on other things. It is reported that when there is a problem with the skin, it is usually related to a blockage at T4 on the spine. Tong Ren can be used to open this blockage. For more information, check out:

In terms of eating well, my recommendation is simple. Avoid supplements. Just eat a variety of good foods from nature. Stay away from man made substances. And drink some clean water.
Good luck!
