Lutein: The skin is exposed to multiple environmental aggressions which can lead to premature aging. Of these agents, the most present is ultraviolet (UV) radiation from sunlight.
The main defense against damage to the skin is the antioxidant capacity of the skin. However, this defense system can be compromised by UV exposure.
Lutein
Carotenoids (lutein, zeaxanthin, beta-carotene (provitamin A)) trap free radicals caused by the sun's rays.
Lutein and zeaxanthin are two potentially important antioxidants found naturally in the skin.
Lutein and zeaxanthin provide a very high degree of antioxidant protection for both eyes and skin and protect against UV exposure.
Lutein vision, degeneration, cataract night vision, oxidative stress
Lutein is a carotenoid found in the macula and skin, the body does not produce it and must be obtained from food. The antioxidant virtues of lutein effectively protect vision, it filters blue light and prevents cataracts and degeneration. Lutein increases lipids in the epidermis to protect the skin from ultraviolet rays and the sun. Lutein, zeaxanthin, blueberry to take for the vision.

Lutein description
Lutein (C40H56O2) is one of the six hundred known carotenoids and more precisely one of the three pigments present in high concentration in the retina, it forms a tiny yellow spot that does not measure more than two millimeters in diameter in the macula. This particular shade of lutein is due to the percentage of its concentration, it is yellow in the event of a low rate and red-orange at high concentration. It is good to know that this carotenoid is not synthesized by the body and yet it is essential for the proper functioning of the skin and vision.
The source
To obtain lutein, only food intake can be considered, either through the daily diet which favors foods that contain it or as a food supplement.
In the diet, it is mainly found in yellow vegetables such as corn and carrots, in green vegetables with leaves, such as spinach and sorrel, lettuce and broccoli as well as cabbage and peas. It is also localized in some fruits such as oranges and peaches, the flowers only the edible one of course with the marigold and finally it is present in the egg yolk.
Lutein deficiency
Unfortunately the intakes of lutein in the daily diet are generally insufficient, due to an unbalanced diet or the consequence of other factors, such as smoking and alcohol, which are often responsible, pregnancy and breastfeeding also which generally results in a deficiency in this carotenoid. And this deficiency can have negative effects, especially on the eyes and skin.
Its medicinal virtues
Lutein has the most effective antioxidant qualities, in fact it filters blue light and stops the action of free radicals responsible for numerous damage to the eyes. A contribution of this carotenoid, allows to considerably reduce the risk of contracting a cataract and to prevent the degeneration of the retina (AMD), thanks to its protective power and to an increase in the density of the macular pigmentation, important to protect the vision. . In addition, lutein is often associated with zeaxanthin (another carotenoid), because they are very effective in preventing the risk of eye problems.
With the taurine which is an amino acid concentrated in the retina, lutein, zeaxanthin and taurine are a winning trio.
Lutein is also of great benefit for skin protection, it increases the level of lipid in the epidermis, allowing the skin to be protected from certain external aggressions. This results in a better tolerance to the sun, to reduce the inflammatory reactions caused by ultraviolet rays, as well as a reduction in the intensity of redness caused by the sun (sunburn). It was also demonstrated the importance in terms of dermatological protection of a supply of lutein to help reduce the damage caused by these ultraviolet rays.
Lutein other uses
Lutein is also an orange-red natural pigment which is used as the coloring agent E161b, and which is used to tint the skin of poultry yellow and therefore more attractive to consumers.

Zeaxanthin
Zeaxanthin is a pigment from the carotenoid category, which is mainly found in the retina. It is by its presence a preventive of macular degeneration and cataracts, two diseases related to age. Zeaxanthin intake dramatically improves visual acuity, reduces glare and helps filter out some of the sun's rays.
AMD, oxidative stress food supplements for vision

What is Zeaxanthin?
It is one of the three pigments with lutein and mezozeaxanthin of the carotenoid or xanthophyll family which are localized in large concentrations in the central part of the retina of the eye, and more precisely in the macula. Zeaxanthin is defined in crude isomeric formula under the name C40H56O2, it is this which gives the yellow color to corn kernels. It is essential for the body, it enters the visual process.
The source
Zeaxanthin is absolutely not manufactured by the human body, it is essential that a daily intake be made through food or with food supplements based on this carotenoid.
The food source, can be found in a good number of vegetables and fruits, in cauliflower and red peppers, broccoli and corn, salad and citrus fruits, and eggs.
Zeaxanthin deficiency
A deficiency can quickly occur, because the intake of foods containing this carotenoid must be daily, and nowadays, it is common for humans to have an unbalanced diet. But certain factors such as tobacco and alcohol play an important role in this deficiency, and their consequences can cause certain disturbances on the vision.
The medicinal virtues of zeaxanthin
Zeaxanthin is a pigment found in the eye. By its action, it is an important element in the protection against the risks of macular degeneration (AMD) and cataracts. It is obvious that if we can combine zeaxanthin and lutein with blueberry, it reinforces this protection. It has been proven by numerous medical studies and clinical trials that a combined intake of these two carotenoids will increase the density of the macular pigment and protect vision more effectively.
It is a powerful antioxidant, which works by reducing photooxidation (oxidation by light) by filtering out blue light, but also by reducing glare, and increasing contrast and to help improve visual acuity. This carotenoid acts as a filter and prevents oxidative stress.
Other uses of zeaxanthin
Sovent used in the same way as lutein, they are also used as a food additive under the number E161h except for the European Union because zeaxanthin is not listed as an additive.
