If you are getting a headache then I would not use this treatment.
Acne is a sign of underlying health problems. It is a natural way for the body to release toxins when too many toxins are built up.
I cured my Acne by following a moderate, balanced, vegetarian diet, along with colon cleansing. My health is still not perfect but now the Acne is easy to control with no topical treatment.
I currently follow an ayurvedic diet based on ancient Indian teachings and am having much better results on this diet than the basic cure-zone recommended diet.
