In a prospective study of more than 47,000 adults followed for over eight years, those with the highest lycopene intake had a risk of prostate cancer that was 21 percent lower than those with the lowest intake. They’re also made from certain species of algae and even some bacteria. UV damage can cause premature aging, wrinkles, dry skin, as well as melanoma. This instrument utilizes the Commission Internationale de l'Eclairage (CIE)2L*a*b* color system to determine skin color objectively. All rights reserved. In addition to supporting a healthy pregnancy, beta carotene benefits the skin, as well, by offering protection from damage.

This coloring comes from the carotenoids being deposited through each skin layer. Most commonly, carotenoids are known for benefitting eye-health and other age-related conditions, but their importance to skin care is becoming more apparent. By lowering the amount of blue light that’s able to enter the eye, carotenoids help preserve healthy cells and slow down oxidative damage that leads to vision loss. One of the ways that carotenoids help with growth is because they allow cells to communicate with one another by playing a role in the synthesis of connexin proteins. You don’t need a large amount of fat to help utilize these nutrients best. Carotenoids are a source of pro-vitamin A, they contribute to healthy skin color, they may help support normal vision, and there are some tantalizing reports of improvements in cognitive function after intake of certain carotenoids. Infants and toddlers need vitamin A for normal growth, development and building a strong immune system. Carotenoids can serve as marker substances for the complete antioxidative network of human skin. Two of the most commonly known carotenoids are lutein and zeaxanthin. The carotenoids that have been most studied in this regard are beta-carotene, lycopene, lutein, and zeaxanthin. In part, the beneficial effects of carotenoids are thought to be due to their role as antioxidants. Antioxidants are essential for the skin, especially since overexposure to UV light can cause a reduction in the antioxidant supply, thereby increasing oxidative stress. The contribution to skin color is subtle, but you can determine the intake of carotenoid -rich foods by measuring their skin color. They act as antioxidants and have significant cancer-fighting properties. Some of the major benefits of a well-rounded diet that includes carotenoids of all kinds include: Once consumed, carotenoids have antioxidant activities that help block the formation of oxidative stress, the primary cause of aging and degeneration.

Protects the Skin. Studies have shown that people who consume high amounts of lutein and zeaxanthin tend to experience less age-related eye problems, including macular degeneration and cataracts. Connexin proteins are needed to form a protective membrane layer around cells and the gap between cells where chemical signals are sent. Now let’s look at the natural benefits of beta carotene for skin. (5). Vitamins like E and C are known to support skin health, but other nutrients including carotenoids—and specifically lutein and zeaxanthin isomers (RR- and RS [meso]-zeaxanthin)—may be just as important in building a whole-body, first-line defense against environmental assaults. The most notable of the carotenoid family are beta-carotene, lycopene, lutein and zeaxanthin. While we know that carotenoids have antioxidant properties that help decrease free radical damage, researchers are still trying to figure out how else they promote better health. Carotenoids have anti-inflammatory, antitumor, chemoprotective properties that help us ward off common infections, illnesses and serious diseases like cancer too. Accurate and objective measurements of human skin color can be made using a tristimulus chromameter (1–6). Once we eat a food that contains carotenoids and the food makes its way to our intestines, the carotenoids comes into contact with our bile salts and several types of lipids (fats) that help break them down. beta-Carotene may have added benefits due its ability to be converted to vitamin A. These carotenoids are the only two that are found in the retina and lens of the human eye, which is why they’re accredited with improving eye health and protecting vision. A portion of carotenoids are incorporated into lipoprotein, which makes it way to the bloodstream, while others are sent to the liver. Cells that line our intestines help dissect the chemicals that make up cartoenoids and release them into our bloodstreams. They also reduce water loss so help hydrate. Vitamin A is found in two primary forms: active vitamin A and provitamin A, which are carotenoids that need to be converted. This condition is characterized by yellow-golden flecks in the eye, and sometimes vision field defects and problems with vision clarity.

The health benefits of carotenoids generally derive from their vitamin A activity in the body These benefits include support for the skin, immune system, heart and eyes Carotenoids are a class of red-orange pigments that are primarily produced by photosynthesizing organisms such as green plants. Carotenoids are not only critical for the process of photosynthesis, but also for helping mitigate free-radical damage. They also reduce water loss so help hydrate. Chlorophyll and carotenoids are similar in that they both form the pigments found in various fruits, algae and vegetables.

One way it does this is by promoting cell differentiation and inhibiting cell cycle. After 12-weeks, Lutemax 2020 resulted in an improvement in overall skin tone, whiteness/brightness, photo-protection and skin firmness.5. Carotenoids help stimulate epidermal regeneration helping to soften and smooth skin. Within the liver and intestines, active vitamin A is created, but luckily the human body has a mechanism in place that will stall this process when vitamin A levels are already high enough.

Research has shown that antioxidants, including beta carotene, can help maintain skin health and appearance, and may protect the skin against UV radiation from the sun. They do this by absorbing UV light and other rays within the spectrum that damage our eyes, such as blue light that’s omitted from technological devices. Skin is the largest human organ and provides a first line of protection for the human body from its environment.
