I had severe acne and I wanted to share my success in becoming completely clear by reducing the amount of saturated fat I consumed.
I tried and was prescribed many things.
I used different soaps, Retin-A gel, antibiotics (tetracyclines like minocin). Some gave me side effects, none of them cured my acne.
In the end I found that whenever I ate things with a lot of saturated fat in them - things like sausages, batter, butter, biscuits, cakes, some ice-cream, - that my acne would get worse and worse.
When I reduced those things and had things low in saturated fat like fish, vegetables, salads, fruits, potatoes, (garlic seemed to be helpful, seaweed like nori or kelp also) that after a while my acne got better and better and cleared up.
(I was actually ok eating nuts - even some with relatively high saturated fat, but they were the exception).
Now I am completely clear. I can get away with eating some things high in saturated fat now and again. However, if I eat lots of things high in saturated fat for weeks, then my acne returns and gets worse and worse.
I am sharing because I was lucky enough to find the reason for my acne. Hopefully it will help you too.
