Although many people believe that partying too hard, insomnia, coffee and cigarettes all go hand in hand with dark under-eye circles, researchers have now discovered that this is not true.

Dark circles under the eyes are caused by the oxidisation of the blood in the capillary matrix. These sensitive capillaries actually 'leak' blood that begins to oxidise, creating the dark bruised look of serious under-eye circles.

Hylexin has a compound to help optimise enzymatic activity, causing the red-bluish pigmentation to fade. Plus, it helps strengthen the capillary matrix to help stop the 'leaking' and protects the orbital eye area against further damage.

The other great thing about Hylexin is that it's very light. It is quickly absorbed into the skin and doesn't feel gluggy around the eyes. It works best when applied morning and night and can be followed by any moisturiser or concealer. And what I was most impressed with is the speed of its effect.  After just one week of using it, I was already being complimented on my ''eye make up". I soon realised that people weren't meaning my eyeshadow or mascara, but the fact that something was just 'different' with my eyes.

Hylexin can be found at most pharmacies around the country and is absolutely worth the $225 retail price.
