That's great for you. It means that toxins are being pulled from your body.
I've suffered from dark circles for years. Everyone told me they were most likely hereditary, but I've been doing a lot of reading lately, and I've come to the conclusion that they might be tied to allergies, but there seems to be a very clear tie to kidneys.
I've had lower back pain for years, but thought it was from an old skating injury. It wasn't until I started cleansing my kidneys did the pain go away, and my dark circles are staring to definitely diminish. I've also been putting a skin lightener around my eye area. I get this lightener from http://www.skinactives.com.
Don't know if it is one, or the other, but between the two, they are definitely getting lighter. I'm thrilled, since I've had these circles for decades.
Hope yours goes away with the pulling. It could happen that way for you!
