Polyphenols, what are they, and how they tend to affect our skin ...

Our skin is an amazing thing. Not only is it the biggest organ in the human body, but it's also one of the organs that really exists outside the body. The fitness of our skin therefore is dependent on both what we put into our bodies as well as what we put on our bodies. With so many factors having an effect on our skin?s health, two groups of critical items often get overlooked. They're polyphenols and phytosterols.

Plants are like chemical factories producing a myriad of chemicals and compounds that help them to grow, protect themselves, reproduce and regenerate. Polyphenols are a class of organic chemicals that are produced in plants and have anti oxidant benefits. There may be more than four thousand anti-oxidant polyphenols so there's limited research on most of them. Antioxidants help to get rid of free radicals that appear as a result of oxidation. Antioxidants are excellent for us because when eaten they can help to cut inflammation and resulting Problems like coronary heart disease. There is also proof that they can help us when applied topically,eg retarding the method of skin wrinkling and aging.

We will be able to access polyphenols and use them topically by removing the oils of plants that produce polyphenols. In the plants the polyphenols work to prevent rancidity but on our skin they do wonders. We will find 3 differing kinds of polyphenols:
1. Flavonoids
2. Lignans, and
3. Tannins

flavonoids

You will have heard of flavonoids before though not know precisely what they are. Flavonoids are found throughout a plant, including in the pigment of brightly colored flowers. Collectively they are referred to as Vitamin P and are found extensively in nature. They are potent anti-oxidating compounds that have anti inflammatory, anti-microbial, anti-cancer, and anti-allergic properties. Flavonoids can be discovered in citrus fruits, sea buckthorn, red wine, tea, berries and cocoa, solely to cite a couple types of foods. The scientific community agrees that flavonoids have a broad result on different layers of the skin. The top layer of our skin (stratum corneum) is chock-full of lipids and fatty acids which can easily oxidize. Here flavonoids can go to work getting rid of oxidising agents that are generated as a result of oxidization. Further down into the epidermal layers flavonoids can stop UV damage with their antioxidising properties. And in the innermost layer of skin (the dermis), they can help protect the microvessels that feed and feed the skin. It's no wonder than many skin formulations are beginning to harness these powerful antioxidants.

Lignans are phytoestrogens which both act as anti-oxidating compounds and are estrogen-like chemicals. Lignans are present in a lot of plants including flax seeds, sesame seeds, soybeans, pumpkin seeds and apricots. Since lignans are antioxidants, they also scavenge free radicals on our skin when applied topically.

If you have had a tumbler of red wine and then tasted that puckery feeling in your mouth after, then you know what a tannin is. Tannins are a bitter type of polyphenol that are acid, and they occur in more plants than just grapes. Green tea, witch hazel, pomegranates, berries and nuts are examples of other types of plants with high levels of tannin. The medical profession is just beginning to research the usages of tannins in the body. Tannins have been shown to have potential antibacterial, antiviral, and antiparasitic properties. They have also proven to be powerful antioxidants with anti-inflammatory properties. It won't be surprising to see more research come out in the next few years on how tannins affect skin health and about how polyphenols and skin are so intertwined.
