Zinc Moisturizers and Vitamin E

You  might have noticed the recent trend for natural skincare products and herbal treatments. One of those treatments is a great anti-acne treatments and natural sun protector call Zinc. Zinc Oxide is a natural mineral that is usually found in a powder form and resembles chalk or calcium.

Modern-day zinc moisturizers contain many natural herbal ingredients along with a base oil or water for moisturizing. One really great oil to use in any moisturizer is Vitamin E.

Vitamin E (also known as Tocopheryl Acetate) has amazing healing and regenerative powers to renew skin cells. The great thing about Vitamin E in natural moisturizers like zinc cream, is you can not only ingest it - but it works wonders topically as well.

Vitamin E, which was only discovered 80 years ago, is an antioxidant that will help you to fight free radicals. Good sources of vitamin E are walnuts, almonds, peanuts, vegetable oils and green leafy vegetables. Vitamin E is stored in your body’s fatty tissue, from where it assists with forming red blood cells, in addition to neutralizing free radicals.

Protecting Your Skin with Antioxidants and Zinc

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, but topical zinc has been proven to block out harmful UVA and UVB rays - the leading cuase of skin aging and skin cancers.

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
