Antioxidants are substances which have been shown to protect cells from damage caused by free radicals. Free radicals are unstable molecules that can cause cell damage or even death if they accumulate in large amounts. When these free radicals come into contact with other compounds, such as proteins, lipids, carbohydrates or DNA, they may react violently causing cellular dysfunction and even cancerous growths.
There are many different types of antioxidants, but they all work in a similar way: They prevent the formation of new reactive oxygen species (ROS) and reduce their effects. The most common type of antioxidant used today is vitamin C. Vitamin C acts as an electron donor and an anti-oxidant. It protects against oxidative stress, which occurs when free radicals attack our cells due to environmental factors like sunlight exposure or smoking cigarettes.
The second most commonly used antioxidant is beta-carotene. Beta-carotene helps to prevent the oxidation of fats and oils in your body. It also prevents the breakdown of proteins, vitamins A and D, and certain hormones. Another well-known antioxidant is vitamin E.
This fat-soluble vitamin protects cell membranes from free radicals. Then there’s selenium, another fat-soluble antioxidant that helps the immune system produce protective enzymes.
While these nutrients are commonly used in the body, there are other antioxidants out there that may be useful in the future. Some of these antioxidants are found in common vegetables and fruits. The best known of these is vitamin A. Others include lycopene, lutein, and zeaxanthin.
There are many others still being researched, such as sulforaphane found in broccoli, resveratrol in red wine, and anthocyanins found in blueberries.
Antioxidants are used to treat and prevent certain diseases and conditions like heart disease, cancer and Alzheimer’s disease. Antioxidants may also help slow the aging process and boost the immune system. Some studies suggest that a proper diet high in antioxidants can reduce the risk of certain cancers, especially those of the lung, mouth, throat, nasal cavity, and stomach.
There are many reasons why you may want to use an antioxidant skin cream. However, it is important to note that taking large amounts of antioxidants orally does not necessarily mean that they will have the same effect when applied topically on your skin. The positive effects of antioxidants in your diet are most likely minimal due to the fact that when ingested, these antioxidants are broken down by the liver before they can be absorbed into the bloodstream. However, there is some evidence that applying antioxidants topically may help reduce the appearance of fine lines and wrinkles around the eyes.
While antioxidants are beneficial for your skin, you should be careful not to overdo it. Applying large amounts of antioxidants on damaged or unhealthy skin can cause redness and irritation. This is also true for people with sensitive skin. It is advised that you perform a skin patch test before using large amounts of this product or apply it on a small area of skin to check for any allergic reactions before applying it on a larger area.
There are many forms of topical antioxidants, including gels, creams, lotions, serums and oils. Topical antioxidants are available for purchase over-the-counter and online.
