Dark Circle "Camouflage" underneath the eyes is a patented technology. I have used it for over 2 years now. I found a great number of people suffer from this problem under the eye area and there is currently no medical or cosmetic application that can solve this problem. "Permanent Concealer" is a method We have developed which places pigment just under the first layer of skin and is not visible to the eye, however this corrective pigment which cannot be seen in the background shows through the vessels and thus the darkness under the eyes is not then apparent. In addition, the procedure of placing pigmentation in areas under your eyes can have a lot of appeal as it also smoothes out fine wrinkles and smoothes the overall appearance of the surface of the skin. The effect of this treatment usually lasts 3 years or more.
