Acne on the chin usually means stress : bad sleep, just standard school stress, ... You often see it in older women (one zit on the side of their chin, like my mother, my aunt, and many other women I saw).

What could really help you is a diet high in fruit and root veggies, coconut oil, gelatin, organs, bone broth etc. and low(er) in muscle meat, leafy greens, ... Ditch the chicken and the pork.

Liver will give you retinol, which should really help with your acne, especially if you don't wanna quit dairy.

Paleo often puts too much emphasis on going low in carbs and supplementing magnesium and vitamin D, but if you have acne every mineral/vitamin/micronutrient is important, not just those two. Calcium should not be neglected, and vitamin k2 can be an awesome addition.

Some people also put too much emphasis on diet and forget "life" in "lifestyle". Make sure you walk a lot, in the sun preferably (don't walk if you really don't want to), make sure you move around and get your blood flowing. I'm not advocating cardio for this, since it would increase stress levels.

An important part of the process is gut healing (acne is probably the result of a leaky gut) : add probiotics, or (preferably) eat fermented foods you tolerate. Start with water kefir, maybe add some sauerkraut or kimchee, etc. Bone broth is a great aid.

All this should already help a lot. Never give up, everybody deserves clear skin, and there is always a solution. The good news is : clearing up acne usually clears up the other health problems first (digestive issues, mood issues, skinny fat body, insomnia, ...)

Before you take antibiotics please read this!

I began suffering from cystic acne at the age of 30. It's been a long slow road, but I finally got it under control after realizing my breakouts were actually inflammatory breakouts to food allergies. Also, I learned that I had leaky gut syndrome, which ties into the above article. I recommend going on a lectin ellimination diet to see if there is a lectin group that you are particularly sensitive to.

Also, pork is highly inflammatory. I break out every time I eat it in any form. I've also found if I eat too much fat or sugar I break out.
Here's another article that discusses the relationship between sugar (in any form) and hormonal acne. http://www.natural-acne-treatments.com/sugar-acne.html

Hope this helps!

You mention a problem with tap water on your skin, have you tried going a week without any tap water on your face? I often read about bad reactions to some types of tap water, though its never clear whether its well founded. Also, have you tried coconut oil and lots of saturated fat but minimum amount of polyunsaturated fats?

I am going to suggest something.

1. NO DAIRY PERIOD. NO HARD CHEESES, soft cheeses, butter or anything like that.

2. Try eating ONLY: vegetables (no nightshades) lots of cabbage family and green leafy ones

               berries (preferably organic)
   
   
           meat/fish/poultry (preferably grass-fed, no eggs)
   
   
   

   No salt, no sugar, nothing else for one week. I would not even take vitamins.

Just try it for a week and see if it makes any difference (it is called elimination diet).

If your acne won't get better with this diet, come back to Paleohacks.

Good luck!!!
