Serious Dark Circles by Bremenn Research Labs .39 oz. 11.53 ml

I have been using this product for at least two years and am extremely satisfied.The apperance of darkness has been elimenated and my eyes have a younger look and no longer look tired . I highly recommend Hylexin .

I have used this product for over 6 months with absolutely no results. I admit that I haven't used it very regularly, but I would expect some benefit after using it for 3 days a week at least. I think this is just a very expensive moisturizer

i rate hylexin low because of the price, but i am sure it works--here's why--after some research, i tried the hylexin knock-off which has the same ingredients that they claim are the 'active ingredients', in a product called 'EyeBryten'. although i have undereye circles, i was looking for something comparable to strivectin sd and strivectin eye cream. well, the eyebryten works. and it was only $20.00 for 1 oz. at major beauty and drug stores. it is better than strivectin (i tried that), and it took the puffiness away almost right away. i see a difference already, and i am pleased. also, an inexpensive replacement for strivectin sd is dermectin (same and better ingredients)--also $20.00 for 6 oz. don't spend alot on some hyped up products! do a little research and read your ingredients, you will always find something better for less!

Hylexin is the only thing that I have found that makes some difference. If used as directed it works. I still need to wear a light concealer, however, that is better than trying to cake it on to hide the circles.

All of the negative reviews here on Amazon were not encouraging. I decided to try it anyway. Why not? I've tried everything else and was seriously considering cosmetic surgery. The price tag of Hylexin guaranteed that I would use it religiously.I have been using this product for 5 weeks. I had very puffy bags under my eyes. After 5 weeks of use, the improvement is dramatic. The best proof is the remarks that I got this weekend from people who had seen me last around week 3. That was great. I wasn't sure if I was imagining the difference.FWIW - I did not notice any change at all for 4 weeks. I use it once every morning and if I remember, I use it in the evening. Dark circles under they eyes are genetic in my family so I wasn't expecting any big improvement in that area.

My daughter and I both bought this. Different skin types and differing degrees of dark circles, so we figured it had to work for one of us. We've both used it faithfully 2x/day for 3 months. ZERO results. Absolutely no difference for either of us. We might as well be rubbing water under our eyes. Save your money. This product is 100% worthless.

After I ordered this product, one of my co-workers told me about the reviews on Amazon. I checked it out and I was really surprised! The reviews are poor. The worst part, though, is that the product is listed three times!! What's the deal?? A product gets a bad review, so they re-list it... more bad reviews and they re-list it AGAIN! See for yourself, do a general search for "Hylexin" and you will see several listings of the SAME product. Trying to out run bad reviews???? I now think less of the product AND Amazon. Shame on you both!

My dark circles are very bad because of allergies and asthma. Putting this on before makeup really helps.They keep making the bottle smaller though, to trick you.
