Protecting Your Skin with AntiOxidants
November 30, 2009 by admin · Leave a Comment
If you want to protect your skin, think antioxidants. These have gained a great deal of attention in recent years, and for good reason. They work to combat the ‘free radical cells’ that damage your skin.
What are free radicals?
Created when oxygen produces by-products during normal cellular metabolism. More accurately, this reactive oxygen ‘steals’ electrons from proteins, DNA and cell membranes, damaging tissue. If left unchecked, free radicals may cause heart damage, cancer, cataracts, and a weak immune system. Free radicals may be involved with aging of tissue; and coupled with sun damage, could promote skin cancers.
While free radicals are produced by normal human metabolism, they can be increased by smoking, alcohol, exposure to heavy metals, and radiation. Antioxidants counteract this process by binding to the free radicals, transforming them into non-damaging compounds, or repairing cellular damage. It would seem logical, then, to include antioxidants in your daily regime.
To the rescue
Antioxidants are the antidote to free radicals. They can be taken orally or applied directly to the skin.
What are antioxidants?
In order for antioxidants to have any benefit they have to be in sufficient quantities in the tissue. Common antioxidants that are taken orally, or eaten, are Vitamin C, Vitamin E, Selenium and the carotenoids, (fruits and vegetables having the most deeply or brightly-colored fruits and vegetables, i.e.: spinach, carrots, red bell peppers, tomatoes).
What are topical antioxidants?
Topical antioxidants may reduce UVA damage. UVA is the wavelength that mostly produces visible signs of sun damage and has some carcinogenic effect.
Topical antioxidants that have been studied in creams or ointments are Vitamin C, Vitamin E, Glutathione, Lipoic Acid, Coenzyme Q10, Soy- isoflavanone. It has been shown that combining some of these have additional benefit. Others such as selenium, zinc and silymarin have not been studied for their effects.
Which are the antioxidants?
Antioxidants can be divided into those that are fat soluble and those that are water soluble.
Fat soluble is:
* Vitamin E, coenzyme Q10 and lipoic acid
Water soluble is:
* Glutathione and Vitamin C
Vitamin E:
* The antioxidant effect can be more effective if combined with other antioxidants i.e.: coenzyme Q10 and Vitamin C
* Is found in fresh vegetables, oils, seeds, nuts, cumin, and soy. Animal studies have shown that Vitamin E protects against UVB damage, although this effect has not been proved in humans. (UVB is much more carcinogenic than UVA, and causes sunburns).
* Commonly used to help wound healing. However, studies in human burns did not show Vitamin E helping and about a 1/5 of patients reacted to vitamin E with a contact dermatitis).
* Topical Vitamin E is commonly used by pregnant women in the belief that it prevents stretch marks. There is no evidence for this, and sometimes an acute allergic dermatitis is produced causing an inflamed uncomfortable rash.
Coenzyme Q10 (also known as Ubiquinone)
* Found in fish and shell fish
* It penetrates well into skin, and is claimed to reduce the breakdown of collagen after exposure to UVA light
* It may reduce the depth of wrinkles but this has not been confirmed in studies
Lipoic Acid
* This is well absorbed into the skin, and converted quickly into dihydrolipoic acid in the cells. It has an anti-inflammatory effect. A three per cent application of Lipoid Acid has been shown to reduce redness in the skin after UVB exposure.
Glutathione
* This antioxidant is produced by amino acids, eysteine, glycine and glutamic acid
Vitamin C
* Also known as Ascorbic Acid
* Oral Vitamin C improves wound healing and may enhance the immune system
* The lack of vitamin C produces scurvy, which produces fragile skin and bleeding gums
Topical Vitamin C
* reduces sun damage, fine wrinkles, and may lighten dark skin pigmentation
Green Tea (Tea polyphenols)
When used topically as a cream
* Has shown to reduce the carcinogenic effect of certain chemicals and ultraviolet rays on the skin of animals. We are still awaiting good evidence for benefit in humans
* Produces anti-inflammatory effects
* Reduces the redness caused by UV light
DHEA (Dehydroepiandrosterone)
* Occurs naturally in our bodies
* When taken orally, DHEA is a powerful antioxidant that may have an anti-aging effect and help thicken skin and reduce pigmentation
* It is not know if there are any long-term negative effects from oral injection
Soy-isoflavones
* When used topically it may increase collagen and decrease redness and damage from ultraviolet rays

Protecting Damaged Skin with Green Tea and Zinc

By Van Le | The popularity of green tea in the skincare industry has skyrocketed over the last decade. It’s more than just a fad, as the benefits of green tea are well documented due to extensive research. Tea was used in ancient times as a natural stimulant, since it contains caffeine. Today, people drink green tea as a natural way to promote overall good health, but it is especially popular in the skincare industry, where it is a key component in the efforts to slow down the signs of aging.
Green tea contains high amounts of polyphenols, which protects the skin from damage caused by free radicals and other harmful toxins. Compared to black and white tea, green tea contains the highest amount of polyphenol, and contains anti-inflammatory, antioxidant, and anti carcinogenic properties. Its anti-inflammatory nature makes it a versatile herbal ingredient used to fight acne. The antioxidant qualities help prevent premature signs of aging, and the anti carcinogenic characteristics are a major component in the efforts to find a cure for cancer.
The anti-inflammatory properties of green tea make it an effective herbal treatment against symptoms of acne. A 2003 study carried out by Dr. Jennifer Gan-Wong of Memorial Medical Center in the Philippines suggest that green tea cream is just as effective as benzoyl peroxide cream, but does not expose the skin to harsh chemicals and preservatives, according to skincell.org. It also helps detoxify the body and reduces skin inflammation, which decreases the occurrences of outbreaks.
Green tea is also indispensable as an anti-oxidant because it contains high amounts of catechins, a substance that fights against free radicals, which are harmful to cells and tissues. Catechin is especially effective in neutralizing free radicals caused by excessive exposure to UV rays.
Although green tea extracts alone cannot replace the protection provided by sunscreen, it can enhance sunscreen’s effectiveness. Simply add green tea extract to zinc oxide products, such as Vivoderm’s Zinc Cream. Using zinc oxide cream instead of a store-bought sunscreen product is recommended because zinc will not react to the green tea extracts.
Anti-oxidants found in green tea help delay the skin cell aging process and heal stressed skin. Green tea promotes healthy skin by rejuvenating skin cells and reviving the skin growth cycle. The skin is produced in the deepest of three layers, and as it ages, it moves closer to the surface, where it can develop wrinkles and fine lines. An article published in the Natural Food Merchandiser magazine states that research done by Dr. Stephen Hsu, a professor at Medical College of Georgia suggests that green tea can accelerate the skin cell production process.
Whether as an ingredient in your natural skincare products or added to your zinc oxide cream, the health benefits of green tea are plenty.
