Acne

Acne is caused largely by the overproduction of sebum, an oily substance that causes the pores of the skin to become blocked, resulting in spots or pimples. They are found on the face, though they may extend to the shoulders, back, arms and chest. The condition is particularly common in the adolescent years due to hormonal changes.

It is thought that acne may be caused by deficiencies of:

vitamin A,
vitamin B6,
essential fatty acids,
zinc and or
vitamin E.
Other factors associated with acne include:

food allergies and intolerances,
a sluggish liver,
a high fat diet,
hormones and
the contraceptive pill.
What you can do to help

Eat as many fresh fruits and vegetables as possible, preferably raw and reduce your intake of wheat and fatty foods.
Take a zinc supplement (30mg every day).
Vitamin B6 supplement is useful for premenstrual acne.
Take a good antioxidant that includes vitamins A, C and E along with selenium.
