parasite cleanses

I have done some parasite cleanses before.

I did one from a naturopathic doctor that involved frequent doses of Black-Walnut tincture.

I did another one that was part of another cleanse (bowel/ parasite cleanse).

My cleanses have never made any positive affect to my skin at all.

I am really at my wit's end.

Worst of all- my skin is being left with permanant scars by the day!
