I think the general Peat recommendations for acne involve getting enough Vitamin A (retinol form) from things like dairy products and liver. To this end, you should ensure that your Vitamin D levels are sufficient too.
For more information I would check out raypeat.com, dannyroddy.com and peatarian.com
Diet can really help get rid of acne. But each individual is an individual case and there's not a one cure fixes all solution. Also each type of spot is caused by different issues. So you need to know what is going on in your body to get to the root cause. Check out Elaine Mummery Acne Clinic or CureofAcne. you will get some good info there.
Ray Peat diet is likely not to help you if you have acne. Peat allows dairy and dairy causes acne in lots of people. Peat advocates drinking fruit juice. This can cause an insulin spike and thus acne because fruit juices are rapidly digested. Peat also advocates higher carb diets. People with acne do better at low carb ranges, that is, 50-70 grams a day.
From what I know, acne is a sign of inflammatory damage. I don't think any diet along can fix the root causes of acne, but it would be nice to know what exactly you are eating or NOT eating. Acne/skin problems is just a sign that something is not right on the inside. I would love for you to try Ray Peat and come back and write if it worked for you or not since I have seen so many questions on acne. EDITED/ I am yet to see people who got better on Ray Peat EXCEPT Korion and Danny Roddy. Only two people so far. I have not heard from any more, and would love to know what they think.
