Protecting Your Skin with AntiOxidants

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

Diet and Supplements for Dry Skin

To combat dry skin, your body needs fats to build fat-rich cells that hold on to moisture. Saturated, monounsaturated and omega-3 fats are key components in the cell membranes . Vegetarians (who eat eggs and dairy products but not meat) eat about one-third less saturated fat than the average meat eater. Vegans (who eat no animal products of any kind) only receive about one half as much saturated fat as the average meat-eating American. As a result, they obtain from their diet much less cholesterol than omnivores.

Although cholesterol has received a bad name due to concerns about its connection with cardiovascular illness, recent studies show that it does have benefits, particularly for some post menopausal women. Cholesterol is needed for key body functions within the cellular membranes that impact the skin. For example, studies show that cholesterol-lowering drugs can lead to dry skin, while decreased levels of essential fatty acids have been associated with dry skin, dry hair, and brittle nails. If you have these symptoms and you are a vegetarian you may want to speak to your doctor to see if you may suffer from an essential fatty acid deficiency.

The best way to assure you get a healthy diet of skin-enhancing fats is by eating a wide variety of whole plant foods. You can get fats from nuts, seeds, olives and avocados Use olive oil, replete with monosaturated fat, for cooking and salad dressings. Coconut oil is also an excellent alternative for it retains its stability at high temperatures. Try to avoid processed foods and deep-fried foods that are rich in trans fats and omega-6 polyrrnsaturated fats. These fats contribute to the production of free radicals, the by-products of oxidation, which is a skin aging process that antioxidant vegetables help tame. Although for many years polyunsaturated vegetable oils, like canola, corn, safflower, and soy were recommended, c anola oil is actually unstable when heated and the processed used to stabilize it turns a certain percentage of the oil into a trans fat.

Eating the undesirable fats found in these oils (as well in trans-fat containing foods such as margarine, most baked goods, fried foods, processed foods and sweets )may increase both wrinkling and the risk of developing skin and other cancers including melanoma. Vegetarians can eat eggs and dairy to obtain saturated fats while vegans can obtain them from coconut oil.

Fish oils are good sources of omega-3 polyunsaturated fatty acids which can increase the lipid content of your cells. They can be obtained from fish like salmon, as well as supplements with Omega-3 or Cod Liver Oil capsules. Omega-3s help your skin by providing essential fats needed for cellular integrity while they also prevent inflammation which can lead to the formation of dark spots in pigmented skin types.
Antioxidants are helpful in fighting free radicals - renegade oxygen molecules that cause cellular aging and wrinkles.

Also look for products that contain ingredients that help your skin retain moisture, such as essential fatty acids along with ingredients like lecithin to strengthens kin cell membranes. Look for products that are also third party tested to ensure they are free of environmental toxins. It is important in purchasing essential fats to ensure that you find a pure, well-tested source, free of environmental contaminants.

Several studies have suggested that it is better to get antioxidants through natural food sources instead of supplements, but if this is not possible or additional vitamin intake is needed, supplements can be a valuable help.

SUPPLEMENTS
The following oral supplements that contain the below nutrients can all be helpful to your skin:

Selenium is a powerful antioxidant mineral. Selenium. Some scientific evidence suggests that consumption of selenium may reduce the risk of certain forms of cancer. However, FDA has determined that this evidence is limited and not conclusive. Vitamins A, C, E, B5, alpha lipoic acid, and grape seed extract, Ester-C , CoQro, lutein, as well as zinc, selenium, copper, and lycopene. Take these supplements according to the manufacturer’s directions.

Taking glucosamine supplements increases hyaluronic acid production. Hyaluronic acid (also called Hyaluronan) is a component of connective tissue whose function is to cushion and lubricate. Vitamin C can be especially beneficial, although it is tough to get ample quantities from supplements, every little bit helps. Be cautious of a laxative effect from vitamin C. take small doses at first then build gradually to endure to reaction has occurred. Buffered vitamin C is also available for those with sensitive digestive tracks. Complementing your daily skin care regimen with skin supportive supplements can boost the benefits to your skin.
