Good question. I also have HUGE black circles under my eyes, but I got them a month before I went into treatment.
I have noticed other people I am treating with looking pale, but I'm the only one with the dark circles. I am thinking it is from insomnia, but also wondering if mine can be from a mildew allergy.
I have researched this question alot, via the internet, but couldn't find any answers. I am thinking it is because I am 49 yrs old, and that this might be a sign of aging.
I had huge black circles under my eyes for quit a while starting at about 40 years of age. I looked ling Uncle Fester from the Adams Family. I quit smoking and before long the black circles filled in with pink. Stupid me! I started smoking again after 4 years of freedom and it didn't take long before the black circles were back. I think it's got to do with blood circulation.
I've had circles & hayfever most of my life....I was guessing they'd get worse, they sayed about even, which is....it looks like I've been engaging the in art of pugilism so I've been using some Nivea Eye gel stuff......It seems to help a little if I keep after it night time.
I can't deal with that silly roller thing so I banged the ball several times on the counter to loosen it up.
Now I just tap, tap, tap tap on my finger & it's works easy....way better than that ball thingy.......
BTW.....Once you loosen the ball, you don't have to do it again.
