"I've been using this product for a week and I've already noticed an improvement around my eyes. They seem lighter and after each application it immediately helps tighten the skin. I can't wait to see what my eyes will look after 4-6 weeks!"

"I have tried some of the other dark eye circle creams and did not have success. I have tried the beeswax one on this site, as well as the one with the black dropper and the seaweed solution... Whatever that one is called. These first two products actually seemed to make my dark circles more pronounced by highlighting my undereyes. I do believe that skin types are different, but I can honestly say that this particular product works awesome for me. I was a little worried because there is a typing error in the directions (not too professional)... but from the first application I noticed a slight improvement. This lotion also works amazingly well at tightening up my wrinkles around me eyes. I am impressed by the results and will most likely use this product the rest of my life. I can not say how permanent the results are- but they look great. The area around my eyes looks tighter and younger and my eyes are not nearly as dark. I am only on day three, but I am very, very happy with this product. My idea for application is to rough up and exfoliate the skin around the eyes in a hot shower- then dry off- and apply this cream carefully with a Q-tip around the entire eye.. Using your finger will probably get this in your eye- and it burns a little... Not terribly- but still... it does burn. The Q-tip can get the dark areas in the corners of your eye and eyelid.. Then I apply a liberal amount to the crow's nest area (twice a day)... This stuff soaks in nicely, is unnoticeable, and does not smell. It does say to use the product for 4-6 weeks for best results. Im sure thats standard marketing ploy- but within three days, I am already impressed. I will continue to use this product and see how much it can do for me. I should also say that the two products I mentioned that did NOT work for me, were reviewed well and people commented how well it worked for them. I did not agree with them, so in all fairness, you may not agree with me on this one. For me, this absolutely 100 percent works and Im satisfied for 11$."

"I have only being using this stuff for bout a month, but being pregnant my baby was taking all my nutrients away. I of course had lack of sleep and even began getting really dark circles from it. Im only 28 so i should not have this yet, so i started using this stuff and it has ligtened up extremly! I took pictures of before and after, the after i just took 3 days ago and it has made a difference and i am very satisfied with that. Most of these beauty cremes and stuff are all just a waste of money,but i would highly recommend this one to a friend =)"

"So far I've been extremely impressed with Vita-K. As a male in my early thirties, I started to develop dark circles, almost a blotchy darker tone under my eyes, along with subtle under-eye bags. Don't be deceived by the cost and cheap packaging of Vita-K, this stuff actually works! And instantly! Even after a week of using the product, I've noticed significant improvement, and hopefully it will only get better with time."

"I have had dark circles since I was a child and I think they are genetic. I have tried so many products to cure or cover them up but nothing works as well as this! The directions say to use it twice a day, but I do not use it in the morning because it messes up my makeup (still have to wear concealer under my eyes but no big deal). besides the makeup issue, my other complaint is that it really stings when i put it on at night, but it stops within a few seconds. the irritation feeling does not leave any puffiness or red marks. but i do notice an INSTANT improvement in my dark circles the moment i put it on. been using this product for years and i swear by it!"

"This product is the best I have found for getting rid of dark circles. I had very dark circles under my eyes and I used this product and they have lightened to almost gone. People tell me how good I look. Great stuff. I highly recommend it."

"I started using Vita-K solution for my undereye dark circles on November 6th. I can honestly say I started to see some results within a week. I have been applying the solution twice daily as directed. The darkness under my eyes has lightened up..but I will continue using this product daily for the best results. I have used it in the past and it worked then. I havent been able to find it in stores so I decided to look online. I would recommend it."

"This product actually works. It took about 60 days of daily use to really see the difference but in the mean time, the tightening effect felt great. [...] I just add what little is left in one bottle to the new bottle I buy.I'm glad I found this product on here because many retail outlets don't carry it."

"American fair-skinned people lack Vitamin K in their diet ... so take vitamin K pills and use this product. First application the dark circles lightened. After 2 weeks the circles were gone. I love this product. You do not have to apply more than a dab ... I use a Q-tip. I can not find a retailer that carries this product so I am very happy that drugstore.com has inventory."

"I like this product as it supports it claims! Use only under your eyes and don't get too close to your lashes as will creep into eyes and burn. After it drys, I use my regular eye cream. I hgihly reccommend this product!"

"I have had DARK under eye circles since I was about 6 years old. I even look "tired" in my middle school pictures. I have tried a bunch of products and this is the only under eye circle product I have ever tried that works! Be patient when you use it because I did not see results until about 4 weeks in. Also, it can cause burning when it gets in your eye, so apply carefully. I am not complaining. This is first time in my life I will let people see me with out "pancake concealer" on!"

"I am 55 and have been using Vita K for several years. I am extremely pleased with the results - dark circles under my eyes disappeared very quickly and have not returned, and I have no crows feet. I use the pump gel in the morning and (when I remember) the jar gel at night. My only complaint is that it is difficult to get the remaining gel out of the very bottom of the pump bottle when it is nearly empty. I wish they had a product for the lines that are starting to appear around my upper lip."

"I have only used this product 4 times and only once a day for the past three because I didn't like the way my makeup went on over it. The instructions say morning and night, I am using it only at night. I have had dark circles my entire teenage and adult life. They have gotten worse over time and are hereditary. This stuff has lightened them significantly already! I saw results the second day. I could not be happier with this product for the price and the difference I see already. I took a chance on it after reading the reviews here on Amazon and thought I would add my experience here for others thinking it's too good for the price. I wish I had taken before pictures so I can compare in a month."

"I HAVE BEEN USING VITA-K PROFESSIONAL DARK CIRCLE CREME AND AM OVER-JOYED WITH THE RESULTS! I WAS SO TIRED OF PEOPLE ASKING ME WHY I LOOKED SO TIRED! THE CREME STARTED TO WORK IN 2 WEEKS AND I HAVE REALLY DARK CIRCLES. MY EYES HAVE NEVER LOOKED THIS GOOD- NOT EVEN WHEN I WAS IN MY TWENTYS AND HAD SOMETHING TO BE TIRED ABOUT. I AM SO DELIGHTED, I JUST ORDERED 3 MORE."

"This product really works!!! I didn't believe at first that a face cream would actually reduced the appearance of eye dark circles. My wife dark circles were huge and very obscured and this product really reduced them to normal levels. The dark circles didn't dissapear, and I think it was because they were very severe, but my wife is very happy to have just very mild dark circles now instead of really black ones. The process is very simple, just use it as directed. Twice a day for 4-6 weeks and once a day there after. You get results from the very first application as advertised. My wife says that you don't feel the cream arround your eyes, no discomfort at all (not oily, not dry). It's like having nothing at all on you. I totally recommend this product, and I am giving 4 stars because it didn't remove the dark circles completely but I am very satisfied (so is my wife)."
