I have no idea how it works, but i am now a believer! i had a really bad allergy to dust, well, dust mites. Anytime i would go somewhere dusty i would immediately start sneezing, with watery eyes and a stuffy, runny nose. Just after two treatments (i seemed to have needed two because it was really bad) i dont seem to react anymore, or if i do sneeze its only after being exposed for a long time. I think Dr Karen Tan has some kind of magic, and I'm definitely planning to go back to try out other treatments.
