During my time as an acne sufferer I have crossed off the following:

• Over the counter Acne Products.
• Modern Medicine Medication.
• Thyroid & Hormone Testing.
• Kidney & Liver Function Tests.
• Food Intolerance Testing.
• Vitamin/Mineral Deficiency Testing.
• Omega 3's.
• Body Cleansing, Lungs, Liver, Pancreas, Kidneys, Colon.
• Improving Digestion, pro-biotics, enzymes, herbs etc
• The Low GI diet.
• Androgen Blocking.
• Progesterone Cream.
• Electrolyte/Hydration.
• Acid/Alkaline Balancing.
• Chinese Medicine.
• Internal Parasite Cleansing.
• External Parasite Cleansing.
• Anti Nuclear Antibody Testing (autoimmune disease)

What I haven't tried:

• Helminth Therapy (still no proof my acne is allergy/autoimmune related)
• Heavy Metal Toxicity Testing (seems unlikely)
• Hormone Allergy Testing (does this even exist?)
• Coronary Checks (I doubt cardiac problems cause acne)
• Neurological Screening (enteric nervous system (digestion))

I feel so cheated, having tried so much, I should have had my day in the sun by now.

Hopefully this list can inspire some possible causes & treatment protocol for some people.

Comments or suggestions appreciated.
