I get anywhere from 6-7 hours of sleep, so I have some circles, but I've gotten used to limited sleep and they are not so noticeable anymore.
If you're really serious about removing these circles, and it sounds like you are, then you should try a better quality product. Sure, it cost a few more bucks, but it's well worth.
I would suggest Clinique, Estee Lauder, or Lancome at the very least. These would be purchased from any department store at your local mall. They do tend to be a bit cheaper at places like Robinsons May and Macy's than Nordstroms, but not by more than a buck or two.
For an ounce, I'd say it would be anywhere from $18-$26.
The storelady's behind the counter would all be very happy to help you. You just tell them more or less your condition and needs, and they might let you test a few products out, and see which one fits you best.
I hope your search goes well, and that soon you'll be rid of those pesky dark circles!
Oh, also nearly always will either of these brands I've mentioned above, have a gift with your purchase of something at or above a price limit. If you would like to buy a little something extra for yourself, or another, It's well worth being given an extra little something.
I get circles under my eyes all the time. Even on the weekends when ill have almost 11 hours of sleep! I'm probably not using the right products, because whenever i put on the concealer, people comment on how it makes my skin look wrinkly and even baggier in some lights. I know how you feel. i need tips too. :-(
I can't confirm this but someone told me that dark circles can be caused by a lack of nutrition from when you were a baby. You should ask a Doctor and find out if that might be the case.
