When To Use Additional Anti Aging Skin Care Products
Anti aging skin care is all about protecting your skin from the negative effects of the aging process. As we all get older the natural defenses of our skin, the same ones we took for granted at a younger age, weaken. Anti aging skin care products can help to maintain a younger and fresher looking skin for as long as you possibly can.
However, looking after your skin doesn’t just end when you use the latest anti aging skin care products as seen on TV. Along with maintaining your good looks, anti aging skin care is also about maintaining your bodies ability to resist disease.
Although recent years have seen peoples awareness of anti aging increase, because of the fact that generally speaking the process of getting old is gradual, a lot of people are still unable to recognize the symptoms of aging skin. They are therefore unable to notice the tell tale signs that point to when to start using additional anti-aging skin care products.
Here is a list of some visible signs that will help you in the planning and execution of your anti aging beauty regime:
Loss of eyesight
Loss of hearing
If you notice the onset of one or more of the symptoms above, it’s an indication that you need to quickly put in place an anti aging supplement regimen. We are talking here about the introduction of additional anti aging skin care measures, we are not talking about starting an anti aging skin care regime at this point.
Anti aging skin care should start well before the signs of aging skin first appear. Serious anti aging skin care is building and following a proper skin care routine much earlier in life, some say as early as in your teens. Starting this young means you require nothing special (expensive), just using the top rated over the counter anti aging skin care products, along with a few other simple to follow natural anti aging skin care steps like eating lots of fruit and veg, avoiding stress, drinking a lot of water and using natural therapies, can go a long way to delaying the aging process.
When the signs of aging start showing, you should start using additional measures like an anti aging vitamin regimen to help offset natural loss through aging. The market is awash with affordable anti aging skin care products that are designed to accomplish this.
Also, with age, the skin undergoes significant change. So you will need to analyze your current skin care procedure to check if it still holds good or if you might need to employ the use of anti aging skin care products recommended by a dermatologist.
Above all else, you should recognize that aging skin is a natural process that eventually happens to everyone and there is nothing that can completely stop it from happening. Whatever they may proclaim, even those much publicized celebrity anti aging skin care products can only go so far in helping to delay the signs of aging skin.

Here are the anti aging products reviews of the 5 top rated anti aging products, plus the runner up in each category. The categories are as follows; body lotion, eye cream, instant wrinkle smoother, lip treatments and facial moisturizers with a SPF of at least 30.
All of these top rated anti aging products can help in your bid to slow the aging process, and in certain situations even drastically reverse any damage that might have been done in the past on your face and body.
Best Anti Aging Treatments Body Lotion
As we get older, our skin cells are easily shed which can leave us looking dry and wrinkled. To keep our skin beautiful and looking youthful, the need for us to better hydrate our skin, moisturize and exfoliate regularly grows.
The winner in the category best anti aging body lotion was won by Fresh Sugar Acai Age-Delay Body Cream.

Proven to be excellent on dry, crazed skin, you will want to use this if your skin is prone to cracking through extreme dryness to help strengthen and firm.
Anti Aging Eye Cream
Many people claim that skin on the hands are first to age, and they might be right, but we all tend to worry more when those fine lines and dry, sagging skin is facial, no doubt because it’s the first thing we see in the mirror in the morning and also the first thing people look at when we meet. And eyes are the area of the face we obsess about the most.
In this category, Amore Pacific Time Response Eye Renewal Anti Aging Creme was voted as the best anti aging treatments for eye skin care due to the wonderful results it delivers around the eye region. Although the product is only half an ounce, it will last a long, long time if used as directed. If the budget is tight ladies this is not for you as it is not a cheap for such a small amount but results are what matters and this delivers.
We know the signs of aging that are common around the eyes; fine lines; dark bags; crows feet; to name but a few, if you notice any appearing this product will not only firm those areas but it will turn the skin around the eyes from that dull, un-shiny look to a more luminous, natural, youthful glow.
In the past, when you were younger and your skin could take the harsh treatment, you probably applied anti aging facial treatments quite vigorously. Now you are older the skin around the eyes is more susceptible to damage from such treatment so care should be taken when using anti aging eye products. Gently pat the product onto the skin, don’t rush it, take your time and use your little finger, you don’t want to further damage the skin in this area.
Second was . This hypoallergenic product comes in at just half an ounce as well and also promises to firm up the skin around the eye area. The main active ingredient are tocotrienols, which are a crucial component of the vitamin E.

Anti Wrinkle Skin Care
I don’t personally know of one single woman who is comfortable with their wrinkles. Obviously we instantly notice the ones that pop up on our face but they have also have this (bad) habit of appearing in other place on the body.
To rid yourself of these little blighters, the winner of the anti wrinkle skin care category, Skyn Iceland Angelica Line Smoother, uses a unique blend of portulaca extract, ginseng, tomato extract and rice bran, all packed into a 1.5 fl. oz. container.
Not one I have used myself in the past, but it recommends using as a spot treatment and working into the lines and wrinkles around the mouth and eyes. It is said to start working in only ten minutes by relaxing facial muscle tension, the cause of the appearance of lines and wrinkles. Due to the small amount used, because you are not smothering the area to be treated, this will last you a long time.
It claims to help by increasing collagen production and enriches your skin with the minerals from the Icelandic water it contains. Berries and extracts are also included which help de-stress the skin around the eyes and mouth
Fatty acids that plump the skin and offer cells protection from toxins and many other every day hazards that your skin is subjected to. Aimed at those who are uneasy with botox but who want the results botox can give.

This product also claims just a ten minute waiting time before you are able to see some results. It’s ingredients are designed to work at keeping your skin looking younger by restoring health to the skins cells.
Although aging skin is a major cause of fine lines and wrinkles there are many other factors that can accelerate their appearance, you need to be aware of these and always look at taking precautionary measures no matter what anti wrinkle skin care lotion you use. Two of the biggest causes are through smoking, which causes lines around the top lip and corners of the mouth, and exposure to the sun. Both are preventable, it’s always worth thinking before hand of the long term damage these activities can do to your skins age health.
Anti Aging Lip Treatment

Why would we ever want to put up with lips that are dry, wrinkled or even cracked. To maintain your ageing lips you need the best anti aging lip treatment on the market and nothing less.
The winner of the anti aging lip treatment category does everything you need a lip treatment to do…give you youthful looking lips.

Used twice a day, preferably under your normal lip-stick, this hypoallergenic anti aging lip treatment is perfect for those with sensitive skin and is also said to help return the rosiness to the lips that we lose as we get older.
Anti Ageing Facial Moisturizer (With SPF 30)
Nothing has such a negative impact on your anti aging facial skin care than the sun…fact. Whether from the increase in the risk of skin cancer or from the damage done to your skin from the harsh rays, the sun is public enemy number one when it comes to facial anti aging. But help is at hand in the form of Neutrogena Rapid Wrinkle Repair with SPF30, voted number one anti aging facial cream.
Using only an amount the size of a pea, which is good because you get a full one ounce of product, you can safely apply the product to the whole face and neck area and the Retinol Sa present in the product immediately works on the lines and wrinkles, plumping and smoothing them away. You also get the benefit of full UVA and UVB protection making it perfect for everyday use.
Best applied in the morning, before you put on your make up. Massage the product in, applying to the face and neck, then allow it to absorb and dry completely before applying your foundation etc.
Next best anti aging facial products was Roc Multi Correxion Lift Anti-Gravity that comes in a 30% larger container at 1.3 ounce. You apply it much the same as any anti aging facial cream daytime moisturizer. This is another great anti aging product to help prevent sun damage to the face as it includes retinol and has a SPF of 30.
Consumer reviews highlight how the product has the ability to even out over time the tone of the skin, which in layman’s terms means that age blotchiness is reduced or even eradicated completely. Most all users commented on the youthful look they were able to achieve after only a small amount of use.
Customers even reported a lack of the need to wear foundation under their make up after applying the product, as the results they got were far superior with just the Roc Multi Correxion Lift Anti-Gravity.
It may seem early, but, like a pension, it is best to begin your anti aging regimen as early as in your teens, though few seldom do. Even if you are advancing in years or consider you may have passed the point where any anti aging skin care would be a waste of time, it’s never too late to begin just one of the many available anti aging systems. Get out there and give it a real go, it can and will make a difference to your appearance.
All good anti aging products in their own right, these are going to help you fight the signs of aging, but never forget even though it’s important to treat your skin topically, hands; face; body; it is just as important to consume the correct anti aging foods. Proper nutrition is essential for supplying the nutrients and vitamins you need to look good on the outside and also protect what you can’t see on the inside.
Cleanse, Tone & Moisturize
This video shows how you should implement cleansing, toning and moisturizing as part of a program of anti aging beauty treatments. One of the videos from Liz Earle Naturally Active YouTube channel.
It looks like we are a step nearer to unlocking the science behind a new generation of anti aging treatments, medicines and tablets. Read on to get the full picture…
A new study demonstrates what researchers consider conclusive evidence that the red wine compound resveratrol directly activates a protein that promotes health and longevity in animal models. What’s more, the researchers have uncovered the molecular mechanism for this interaction, and show that a class of more potent (anti aging) drugs currently in clinical trials act in a similar fashion. Pharmaceutical compounds similar to resveratrol may potentially be used as anti aging treament and prevent diseases related to aging in people, the authors contend.
These findings are published in the March 8 issue of Science.
For the last decade, the science of aging has increasingly focused on sirtuins, a group of genes that are believed to protect many organisms, including mammals, against diseases of aging. Mounting evidence has demonstrated that resveratrol, a compound found in the skin of grapes as well as in peanuts and berries, increases the activity of a specific sirtuin,SIRT1, that protects the body from diseases by revving up the mitochondria, a kind of cellular battery that slowly runs down as we age. By recharging the batteries, SIRT1 can have profound effects on health.
Mice on resveratrol have twice the endurance and are relatively immune from effects of obesity and aging. In experiments with yeast, nematodes, bees, flies and mice, lifespan has been extended.
“In the history of pharmaceuticals, there has never been a drug that binds to a protein to make it run faster in the way that resveratrol activates SIRT1,” said David Sinclair, Harvard Medical School professor of genetics and senior author on the paper. “Almost all anti aging drugs either slow or block them.”
In 2006, Sinclair’s group published a study showing that resveratrol could extend the lifespan of mice, and the company Sirtris Pharmaceuticals, which was started by HMS researchers, was founded to make drugs more potent than resveratrol. (Sinclair is a co-founder of Sirtris, a GlaxoSmithKline company, and remains a scientific advisor. Sirtris currently has a number of sirtuin-activating compounds in clinical trials.)
But while numerous studies, from Sinclair’s lab and elsewhere, underscored a direct causal link between resveratrol and SIRT1, some scientists claimed the studies were flawed.
The contention lay in the way SIRT1 was studied in vitro, using a specific chemical group attached to the targets of SIRT1 that fluoresces more brightly as SIRT1 activity increases. This chemical group, however, is synthetic and does not exist in cells or in nature, and without it the experiments did not work. As a response to this, a paper published in 2010 surmised that resveratrol’s activation of SIRT1 was an experimental artifact, one that existed in the lab, but not in an actual animal. SIRT1 activity in mice was, the paper claimed, at best an indirect result of resveratrol, and perhaps even a sheer coincidence.
As a result, a debate erupted over the particular pathway that resveratrol and similar compounds affected. Does resveratrol directly activate SIRT1 or is the effect indirect? “We had six years of work telling us that this was most definitely not an artifact,” said Sinclair. “Still, we needed to figure out precisely how resveratrol works. The answer was extremely elegant.”
Sinclair and Basil Hubbard, then a doctoral student in the lab, teamed up with a group of researchers from both the National Institutes of Health and Sirtris Pharmaceuticals to address this question.
First, the team addressed the problem of the fluorescent chemical group. Why was it required for resveratrol to rev up SIRT1 in the test tube? Instead of dismissing the result as an artifact, the researchers surmised that the chemical might be mimicking molecules found naturally in the cell. These turned out to be a specific class of amino acid, the building blocks of proteins. In nature, there are three amino acids that resemble the fluorescent chemical group, one of which is tryptophan, a molecule abundant in turkey and notable for inducing drowsiness. When researchers repeated the experiment, swapping the fluorescing chemical group on the substrate with a tryptophan residue, resveratrol and similar molecules were once again able to activate SIRT1.
“We discovered a signature for activation that is in fact found in the cell and doesn’t require these other synthetic groups,” said Hubbard, first author of the study. “This was a critical result, which allowed us to bridge the gap between our biochemical and physiological findings.
“Next, we needed to identify precisely how resveratrol presses on SIRT1′s accelerator,” said Sinclair. The team tested approximately 2,000 mutants of the SIRT1 gene, eventually identifying one mutant that completely blocked resveratrol’s effect. The particular mutation resulted in the substitution of a single amino acid residue, out of the 747 that make up SIRT1. The researchers also tested hundreds of other molecules from the Sirtris library, many of which are far more powerful than resveratrol, against this mutant SIRT1. All failed to activate it.
The authors propose a model for how resveratrol works: When the molecule binds, a hinge flips, and SIRT1 becomes hyperactive.
Although these experiments occurred in a test tube, once the researchers identified the precise location of the accelerator pedal on SIRT1 — and how to break it — they could test their ideas in a cell. They replaced the normal SIRT1 gene in muscle and skin cells with the accelerator-dead mutant. Now they could test precisely whether resveratrol and the drugs in development work by tweaking SIRT1 (in which case they would not work) or one of the thousands of other proteins in a cell (in which they would work). While resveratrol and the drugs tested revved up mitochondria in normal cells (an effect caused activating by SIRT1), the mutant cells were completely immune.
“This was the killer experiment,” said Sinclair. “There is no rational alternative explanation other than resveratrol directly activates SIRT1 in cells. Now that we know the exact location on SIRT1 where and how resveratrol works, we can engineer even better molecules that more precisely and effectively trigger the effects of resveratrol.”
The researchers plan on continuing academic-industry collaborations with the goal of bringing to fruition anti aging drugs that treat diseases associated with aging.

Study Shows How Contact Lenses Can Affect Your Appearance Over Time | AntiAging
And it’s true for both hard and soft contact lenses, according to this new study involving identical twins

While contact lenses might improve your eyesight without the need for clunky glasses, they might also be having an unintended effect on your appearance. According to a new study published in Aesthetic Surgery Journal, use of contact lenses seemingly leads to eyelid droopiness.

Researchers reviewed photographs of 96 sets of identical twins who met in Twinsburg, Ohio, on a yearly basis from 2008 to 2010, measuring the level of eyelid droopiness (called “ptosis”) in each.
These 39-year-old female identical twins had differing levels of ptosis. The patients were visually identified from a twins database and had individual ptosis measured in each eye. The twin on the left did not wear contact lenses; the twin on the right did wear contact lenses.

Nine different environmental factors were considered as a potential cause for ptosis, and they were evaluated through an extensive questionnaire and special standardized photography to determine the degree of eyelid droopiness in each twin.
According to the data collected, wearing either hard or soft contact lenses was associated with ptosis. The average difference in eyelid droopiness between twins was 0.5 millimetres. Among twins who didn’t wear contacts, ptosis was around 1.0 millimetre. In twins who wore soft contacts, that number increased to 1.41 millimetres, rising further to 1.84 millimetres for those who sported hard contacts. (Luckily, with the advent of soft lenses, hard lenses have all but disappeared.)
These 65-year-old female identical twins had differing levels of ptosis related to wearing contact lenses. The subject on the left wore soft contact lenses and had less ptosis than her twin; the subject on the right wore hard contact lenses and had more severe ptosis than her twin.

The researchers also looked for links between ptosis and BMI, smoking, sun exposure, alcohol consumption, work-related stress, and sleep — none of which had a statistically significant impact on eyelid droopiness. The association between contact use and ptosis has been long assumed but never proven, says lead study author Bahman Guyuron, MD, FACS, a facial plastic surgeon based in Cleveland, Ohio.
“Since the identical twins are genetically destined to have similar facial and eyelid features, if there is a difference, it is primarily related to the environmental factors,” Guyuron tells Yahoo Health. “We were able to demonstrate that, of the external factors unrelated to the genes or ageing, use of contacts was the only factor that linked to the droopy eyelids.”
Guyuron says the effect they saw was “related to the weakening of the muscles that lift the upper eyelid, and not related to loose or redundant eyelid skin.” And while the mere-fractions-of-a-millimetre difference might seem small, it’s enough to affect vision and appearance.
“Even a minimal droopiness of the eyelids denotes lack of vigor, tiredness, and getting old — often prematurely on the contact lens users,” says Guyuron. And in a culture constantly seeking the fountain of youth, this may matter to some.
Guyuron says that plastic surgeons regularly perform a couple of key procedures for droopiness. According to data from the American Society for Aesthetic Plastic Surgery, 165,714 eyelid procedures and 31,315 brow lifts were performed on patients in 2014.
“Correction of droopy eyelids is one of the simplest and most rewarding surgeries that plastic surgeons do,” says Guyuron. “It is usually a very short procedure, it often requires very minimal recovery, and it makes the patients look younger and more energetic.”
Of course, eyelid droopiness will occur with each passing year anyway — and you can always switch to glasses if you’re concerned about the effects of contact use.
