In his book Toxic Relief, Dr. Don Colbert M.D. explains a
phenomenon that can wreck inflammatory havoc on the body called
intestinal permeability.

A healthy small intestine permits absorption of
substances such as triglycerides from digestion of fats, sugars from
carbohydrates, and amino acids from di and tri peptides. At the same
time, the small intestine filters out substances such as partially
digested food and toxins.

But if your small intestines have been
damaged by actions such as over use of anti-immflammatories like
aspirin or too much alcohol, it may develop microscopic openings or
holes.

These holes allow partially digested foods such as proteins to
pass directly into the bloodstream in a process known as intestinal
permeability. Intestinal permeability can cause ailments such as food
allergies (which can be represented by acne) or chronic skin problems
as seen with acne.
