Green Tea & Zinc Facial Care

What is Tea?

The beneficial properties of tea are attributed to polyphenols. The polyphenols found in tea mainly belong to the subtype called catechins. Polyphenols or catechins are better known as antioxidants that fight free radicals. Free radicals are damaging to skin and body by attacking healthy cells. Green tea has more catechins than black tea; white tea is almost as rich in catechins as green tea but is different in composition and less well studied.

So How Is Green Tea Good For My Skin?

There have been number studies of skin benefits of green tea. One of these studies show protection from skin cancer by demonstrating topical green tea formulations can reduce sun damage.(1) Another fascinating study in 2003 was conducted by Dr. Stephen Hsu of the Medical College of Georgia Department of Oral Biology. His findings determined green tea was able to rejuvenate old skin cells at the end of their life cycle.

A quote from Dr. Hsu’s paper explained, “…we report here for the first time, that at certain concentrations, EGCG or a mixture of the major green tea polyphenols stimulated aged keratinocytes to generate biological energy and to synthesize DNA, possibly for renewed cell division.

Therefore, green tea constituents may be useful topically for promoting skin regeneration, wound healing, or treatment of certain epithelial conditions such as aphthous ulcers, psoriasis, rosacea, and actinic keratoses.” (2) Dr. Hsu went on to comment he was “so surprised” to discover EGCG actually reactivated cells that had migrated toward the surface of the skin to ‘die’.

Green tea appears to manipulate sun damage protection by fighting free radicals and reducing inflammation rather than by blocking UV rays. Therefore, green tea enhances sun protection when used in addition to a sunscreen. To boost sun protection, apply a green tea formula under your sunscreen to elevate the level of sun protection. It is best to combine green tea with zinc oxide-based sunscreens because zinc oxide is chemically inert and should not react with green tea (which some chemical sunscreens might do, especially in sunlight). You can also look for green tea in natural soaps, and other facial cleansers.

Topical green tea is also very beneficial for sensitive skin types by reducing inflammation and irritation in the skin. Wrinkles, skin sag and other signs of aging have been shown to benefit from Green tea. The tea’s antioxidant and anti-inflammatory polyphenols slow down signs of premature of aging

Green Tea and Pimples

A green tea and pimples study suggests it to be as good as benzoyl peroxide cream in treating acne conditions with fewer side effects. Scientific research has shown that green tea fights bacteria, inflammation and reduces stress. Perhaps it would be an excellent candidate for treating acne?

In the study, conducted by Dr. Jennifer Gan-Wong from the Memorial Medical Center in the Philippines, 108 participants were divided into two groups. One applied benzoyl peroxide cream and the other green tea extract cream twice daily for 12 weeks. Subjects were examined and photographed each week by dermatologists. The researchers noted the green tea cream seemed to lighten patients’ skin color and improve the overall appearance of their complexion.

The preliminary data suggests that green tea cream causes fewer side effects than benzoyl peroxide. Patients in the green tea group reported fewer cases of dry skin, itching and allergic responses.

Use green tea at home to boost your skins health, appearance and reduce signs of aging by freezing freshly brewed green tea as ice cubes and use them as a toner. Let them start thawing first before applying directly to the face to avoid irritation. You can also drink green tea or take green tea extract in capsules to benefit from the anti oxidant properties. The polyphenols will reach your skin via the bloodstream in sufficient amounts.

Using green tea in your skincare routine has definite proven benefits to slow skin aging, reduce acne and protect your skin from cancer among many others. Just be aware of the products you choose. Like most antioxidants, green tea polyphenols are oxidized and can lose their active constituents when exposed to air.

Why Natural Skin Care and Zinc are Best for You

Our skin is the largest organ of the body and protects the rest of our organs from outside elements and harm. We have all been taught to take care of our skin not only to look good, but also to be healthy.

The benefits of eating organic, whole foods have been getting a lot of press in recent years. If you want beautiful skin, a healthy inside will reflect a healthy outside. Today, natural and organic skin care is the fastest growing area in the skin care and beauty industry.

Why organic or natural? Beauty products have been known to contain many chemicals such as parabens, to preserve their shelf life. Parabens are actually harmful to the skin, and overall health. Organic skin care products are all natural and do not contain any chemicals or preservatives. The key ingredients used to make these products contain few if any toxins or chemicals.

You may then ask, “Do natural or organic skin care products expire more quickly than others?” The answer is no. In order to extend the product’s shelf life, manufacturers recommend you use something sanitary–such as a spatula–to remove products from containers and always close containers directly after use. It is widely agreed upon that once skin care products of any kind are opened and exposed to air, they should be used or thrown out after 6 months.

When organic or natural skin care products are used to treat skin disorders such as eczema and acne, they are much less likely to cause irritation to sensitive skin. Choosing organic is a beneficial and safe way to take care of your skin and overall health. Today there are many organic and natural skin care lines and products to choose from, including cleansers, toners, moisturizers, make-up and even anti-aging serums. Some organic products you may already have at home are: essential oils like ginger and tea tree, natural plant oils such as grape seed and almond oil, and herbs such as lavender and green tea. You can use these in your bath or make fabulous natural, facial treatments. The internet or your local library has hundreds of great recipes to choose

Organic fruits such as papaya, apples, citrus and cucumbers are proven to have a healthy effect on the skin, due to the absence of toxic pesticides. As you can imagine, there are many great organic and natural skin care lines available for retail, if you’re not interested in making your own home remedies. However, “natural” doesn’t always mean organic and labels can be deceiving; do some research on ingredients that seem skeptical.

Zinc Moisturizers

Zinc is a natural mineral that prevent harmful UV rays from entering the skin by naturally blocking them. Zinc is non-toxic when used as a topical treatment and found to be easily used by those with allergies or sensitive skin issues.

Zinc moisturizers and sunblocks with high levels SPF (15 or more) are broad spectrum: strong enough to prevent burning for a reasonable length of time with the power to block UVA radiation — something that many higher SPF products cannot match!

The intent of this article is to help you be aware what you are putting on your skin and what harmful ingredients may be looming in your favorite skin care products. Now that you know more about natural, organic skin care follow the below home recipe for a great glow!

Make sure that your at home ingredients are certified organic.

Moisturizing Avocado Mask:

1 avocado, 1 teaspoon of apple vinegar, 1 egg white, 3 teaspoons of olive oil. Peel and mash avocado. Separate and beat egg white, add to mashed avocado along with other ingredients. Apply to face and wash off after 20 minutes.

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
