Overview
Hylexin gained a lot of attention for its aggressive marketing campaigns online and in various tabloid magazines. One of the most recognizable aspects of the Hylexin advertisements includes the image of a women with two very large, dark streaks under her eyes. This exaggerated image may catch a lot of attention and make people want to read the advertisement, but the researchers at EyeWrinkleReviews.com tend to be quite skeptical about such techniques. However, even considering these ads, we wanted to reserve judgment on Hylexin until we reviewed the actual product and had the opportunity to investigate the research behind its ingredients.

Featured Ingredients
Hylexin’s sole purpose is to reduce the appearance of dark circles under the eye. Therefore, this product will not affect crow’s feet, under eye puffiness or other signs of aging around the eye. While this already puts Hylexin far below other products in its field, perhaps more discouraging is the fact that Hylexin does not disclose what active ingredients are responsible for its ability to reduce dark circles. Even though the company claims that 72% of those using Hylexin noticed their dark circles fade, we could not substantiate this claim, since the actual study is not available for review. If we were aware of the active ingredients, we could perhaps conduct our own independent research, but since this is not the case, most consumers are expected to take Bremmen Labs (the manufacturers or Hylexin) at their word.

Even if one believes the claim that Hylexin worked in 72% of people trying the formula in their clinical study, this percentage itself is far from convincing. Other eye care formulas, including Dermitage, Dermalogica and other high-end formulas, have conducted similar studies and found the average effect to be in the 85% to 95% range, within only a few weeks. Therefore, Hylexin seems like an inferior product to us. 

Web Site Description
Hylexin’s web site contains a minimal amount of information about the product. No customer testimonials are present on the web site, and the FAQ section seems to merely be a reformatted delivery of the exact same content as is present on the home page. In addition, the so-called “Media” and “In the News” sections are nothing more than areas where consumers see Hylexin’s commercial or read their in-print advertisements. This web site seems to seriously lack any objectivity, as well as lacking the essential information previously noted.

Positives
- None

 Negatives
- Ingredients are not revealed

- Formula may only work on dark circles - will not affect puffiness or crow’s feet

- Web site lacks convincing research or customer testimonials

Conclusion
Considering the high price ($95) for Hylexin, and coupled with the serious lack of information about the product, we cannot recommend it at this time. We worry that many consumers may be drawn in by the product’s clever advertising, without knowing how or why the product works for dark circles. We recommend avoiding Hylexin.
