I have been trying these things for a while. I haven't eaten dairy or any grains in months, I have tried low sugar, low glycemic load and low fat diets, I sleep at least 7 hours a day, and I tried probiotics and plenty of other supplements, and I still have acne. Zinc is the only supplement that really helps. I didn't try meditation, but I don't think that would make much of a difference.
I thought zinc might be working because it inhibits DHT, so I started taking saw palmetto two days ago to see if that helps. I guess I should try topical DHT inhibitors too. For the green tea extract and saw palmetto, did you mean I should apply them topically? And where can I get that green tea cream?
It's weird how I always underestimate people on this forum. I thought you were just some guy who disagreed with the OP, but now I find out that you made an entire website devoted to clearing acne.
I understand your frustration. Acne can be a b****.
When you say you have tried those things, what does that mean? How long did you give them?
Also, it's very much possible that no single thing makes much of a difference on your skin, but combined they might make a big difference. Try to see them as each item adding points to your score

What about food allergies? Have you had any tests done? And I mean real tests, not talking about vega tests, muscle testing or other dubious tests offered by naturopathic practitioners.
I would highly recommend some meditation or relaxation program. Reading between the lines it seems that acne causes a lot of stress and frustration for you? That, unfortunately, can make it harder to get over it. Anyway, stress is a big factor behind acne. In my books it affects your skin much more than diet does. There's a neurotransmitter called Substance P and it's secreted during stress and anxiety. There are substance P receptors in the skin, and it can increase sebum production, inflammation and skin cell growth, i.e. all the pertinent factors behind acne.
And finally, there are real limits to what can be achieved holistically or internally. That's why you really need to treat acne externally also. To address the genetic disposition to getting acne.
Where to get green tea cream? I don't know too many brands, and I don't live in North America so I can't advice you on that. I know that Proactiv has green tea in their moisturizer. Most products in Exposed Skincare kit also contain green tea. I used Exposed and so far have had good results with it.
You can check local drug stores also. They should carry some suitable moisturizers.
And yes, green tea and saw palmetto should be applied topically.
are consuming green tea everyday can reduce the appereance of acne ? and drinking apple vinegar with water will make a good result to acne ?
Drinking green tea may help, but it's far less effective method of getting the ingredients into your skin. Of course green tea may help with insulin resistance and systemic inflammation, so it may help acne other ways.
ACV and water? I don't know what to say about that. Other than that it tastes horrible. Actually, I do remember some studies about the effect of vinegar on insulin resistance. Though not sure the effect is big enough to make any practical difference.
