Green Tea Studies Show Anti-Aging and Cancer Protection
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).
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.

Facts on Vitamin C Products and C Serum
January 16, 2010 by admin · Leave a Comment
Here are 9 facts on Vitamin C Serum from Dr Joanne Turner and her Blog - Skin Revision.
Facts on Vitamin C Products and C Serum - Is it all hype?
I recommend everyone put Vitamin C and E onto their face daily because they protect against UV induced cell damage. It is this sun damage that not only causes premature aging but also skin cancers. However Vitamin C has other properties including being one of the few ingredients that has a science base to show that it reverses signs of aging to the skin.
Vitamin C was originally used in skin care products in the form of ascorbic acid. At a 10% concentration and low ph, ascorbic acid has been shown to stimulate collagen, decrease wrinkle depth and have lightening effects on pigmentation. It was thought that a minimum 10% concentration was required but newer information indicate that lower concentration (5%) may have benefit. It is best to stay with products that have this concentration or above.
9 Facts about vitamin C serums
1. Consumer beware - not all products contain sufficient vitamin C to be of benefit Most products on the market do not have sufficient concentration to be of benefit to the skin. Many companies, keen to cash in on the market trends for antioxidants in skin care, put only miniscule amounts in and consumers unknowingly will buy a product that will be of no benefit. Unfortunately you cannot judge from the prestige or price of the product you buy, you need to look at the concentrations.
2. Vitamin C does not work in everyone For reasons that are not yet known, Ascorbic Acid at a good concentration does not work in everyone. It may only be 60% of the population who get the age reversing benefits of vitamin C. Some people who do not respond to Ascorbic Acid however still get anti-aging benefits from the newer vitamin C derivatives. (Discussed later). Vitamin C, however is a potent antioxidant and you still should get the benefits of protection from UV induced cell damage even if it does not keep you looking younger.
3. Vitamin C in the form of Ascorbic Acid is very expensive. Vitamin C is very unstable and difficult to get into a formulation this in part explains why ascorbic acid skin products tend to be very expensive.
4. Your Vitamin C may oxidise before you get to put it on your skin The biggest problem with Ascorbic Acid creams and serums is that because they are unstable, they are oxidised very quickly and once it is oxidised it does not provide any benefit to the skin at all. Even in stabilised formulations there is a risk that before you get your precious vitamin C cream or serum home, it will already be useless and worse may even because more damage to your skin than good.
5. Watch for yellowing of your serum- it indicates oxidation As it undergoes oxidation the ascorbic acid takes on a yellowish tinge, so it is important to check your creams or serums before you put them on your face, and if there is any yellow discolouration, DISCARD.
There is a problem with the colour check as the first stage of oxidation is colourless, so prior to going yellow it can be in an oxidised state that cannot be detected.
6. Do not buy vitamin C preparations that are tinted yellow or orange The second problem with using a colour test is that many vitamin C serums are tinted and you will not be not be able to detect if it is oxidised by visual checking. Why a company would do this is beyond me, when they know the difficulties of instability of vitamin C formulations oxidising. If you didn’t trust them you would think they are deliberately trying to mislead. Do not buy tinted formulations of vitamin C.
7. Vitamin C derivatives are more stable, less expensive and effective at lower concentrations There are newer derivatives of Vitamin C: Ascorbyl palmitate, Tetrahexyldecyl ascorbate and Magnesium ascorbyl phosphate, and some of these are proving as effective as ascorbic acid in collagen stimulation. Refer Smartskincare an excellent science based skin care site. These derivatives are effective in lower concentrations, are more stable and less expensive and as such may be a better choice. There is a battle among some of the big cosmetic houses as to which is most effective but the newest Tetrahexyldecyl ascorbate if particularly promising, and seems to work in some people who are resistant to Ascorbic Acid.
8. There is nothing special about the base cream or serum that the vitamin C (or any other active product) is delivered in Thinking about it logically, if a product has 10% ascorbic acid in stabilised form, or 2% Tetrahexyldecyl Ascorbate (the active ingredient) then no matter what the cost it will be equally effective, as there is no base serum or cream that has properties that make it effective in anti-aging-and that is the truth.
This is illustrated with my recent comment on Boots no 7 perfect and protect - where a chain store anti-aging cream is matching up to more expensive prestige brands and winning. The reason: it is the active ingredients that has the effect, no matter what advertising trys to seduce you - REMEMBER THIS FACT.
9. You can make your own Vitamin C Serum There is however some ingredients that are now considered state of the art in modern skin care. Among these is a group of base ingredients that help protect the skin and maintain the intercellular network. Refer Cosmetic Cop - Paula Begoun cosmetic ingredients dictionary on natural moisturising factors. These do not have anti—aging benefit but protect the skin and assist in repair. Glycerin is one of these, other very good protectants and natural moisturisers are ceramides and silicones.
Treating and Preventing Sunburn
August 5, 2009 by admin · Leave a Comment
Playing in the sun is not fun if you have to deal with sunburn afterward. On long, hot summer days, we are all tempted to spend the day relaxing poolside or at the beach, and most of us have suffered the consequences of too much sun exposure. The desire for the perfect golden tan can sometimes lead to sunburns, which is very harmful for the skin. If you suffer from acne, a sunburn can further damage your skin and cause permanent scarring.
Sunburn is a delayed inflammatory reaction when the skin is exposed to excessive ultraviolet radiation. Symptoms of mild sunburn, including redness, tenderness and pain, often occur a few hours after exposure, and can last for several days. The pain, itching and peeling is the skin’s reaction to excessive UVA and UVB ray exposure. Although the skin needs time to heal, there are some remedies and treatments available to help the skin repair itself.
Get out of the sun
It may sound simple enough, but we often do not realize we are sunburned until it is too late. Since it is a delayed reaction, the full extent and severity of the burn may not appear until up to 12 hours after exposure. Stop your sun exposure by seeking shade from trees, umbrellas, hats, etc. Drink lots of water, since sunburn causes dehydration. Get some immediate relief for the pain by adding baking soda to a cool bath, and wear loose clothing that does not stick to the body.
Reduce the pain
Anti-inflammatory medicine such as Advil or Ibuprofen can help relieve the redness and pain associated with sunburn. Aloe vera is a popular treatment for sunburn thanks to its ability to moisturize and repair the skin. Apply a moisturizing cream containing Aloe vera, and if possible, apply the gel from the actual plant to the affected areas. Once the burn heals, the skin will begin to peel and may become itchy. Fight the temptation to pick and scratch, which can irritate the skin a slow the healing process. Instead, keep the skin moisturized by applying a moisturizing lotion, which can reduce itching.
Prevent sunburn
The best way to deal with sunburn is to not get one. Sunburn may only seem harmless and temporary, but can have lasting effects on the skin and overall health. Serious sunburn can cause blisters, shock, lead to cancer and even death if left untreated. Protect yourself from the sun’s harmful rays by applying sunscreen at least 30 minutes before going outside. Wear loose, protective clothing and avoid staying outside for too long during peak hours (10am to 4pm), when sunrays are harsh. Choose a sunscreen with SPF of at least 30, and use sun-protection products that contain zinc oxide, an inorganic ingredient that can deflect UVA rays. Try Vivoderm’s zinc cream, a natural product that can be used as a nontoxic sunscreen.

Anti-aging Tips - Skin Care Tips
December 10, 2008 by admin · Leave a Comment
If you want to avoid the early signs of aging, there are plenty of anti aging skin care products available for you. You can also look up tips and guides on how to make your skin firmer and healthier. On the other hand, there are treatments for anti aging, which are easy to follow. These treatments will not take up much of your time. The best skin care treatment does not necessarily involve expensive products. You do not have to buy costly products, in order for you to prevent wrinkles from appearing around your eyes and your mouth. Anti aging tips include simple reminders such as drinking water constantly. As simple as this step, you will be able to keep your skin healthy.
Exposing your skin to an appropriate amount of the sun’s rays is one way of preventing premature aging. Sunlight is capable of providing your skin with vitamin D, which is also great for keeping your teeth and bones healthy. However, too much sun exposure can cause skin problems. This is true especially if you expose yourself to sunlight between 9 AM to 4 PM. During these times, the heat of the sun is harmful and can lead to skin cancer and heat stroke. Minor problems caused by too much UV rays exposure include skin rashes, blemishes, and dark spots on the skin.
If you need to go out, when the sun is really hot, you have to keep yourself protected. You should wear a hat to keep your face away from the sun’s harmful ultraviolet rays. Sunscreen lotion and cream are anti aging skin care products that keep UV rays from penetrating into the inner layers of your skin. However, you have to remember that there are some products for anti aging that are harsh for your skin. One of the best ways to know if the product is good for you or not would be to check its ingredients. You should be aware of products that contain petroleum and alcohol-based ingredients.
Another anti aging tip is to take in much filtered water. Avoid tap water since this contains chemicals that are harmful to your body and to your skin. The sad fact is that there are several individuals that do not consume enough amounts of fluids that are needed by the body. This can lead to dehydration and premature aging. Aside from anti aging skin care products, water is a great way to keep your skin looking radiant. To make your skin healthy and supple, you have to consume at least eight glasses of water everyday. This anti aging guide is better than any kind of skin care product.
You also have to remember that a proper diet is a good anti aging tip. Organic leafy greens are great for maintaining the health of your skin. Green and leafy vegetables are comprised of antioxidants that prevent free radicals from damaging your systems. Free radicals are capable of destroying your cells. Once your cells are damaged, this can cause early symptoms of aging like wrinkles.
Face creams, hand and body lotions, and moisturizers are among the most effective anti aging skin care products. They support your body’s production of elastin and collagen, which help in making your skin appear younger. What is more, these products even out dark spots on your skin and face, and they eliminate wrinkles and fine lines.
