UV radiation

For a six billion-year-old star, the sun is certainly in the news a lot lately, mainly because it is still a source of uncertainty and confusion to many of us.

The center of this confusion is the sun’s ultraviolet A (long-wave) and ultraviolet B (shortwave) rays. Our understanding of exactly what kinds of damage each causes to the skin, and how best to protect ourselves, seems to shift every year as new research comes out. For example, it was once thought that only UVB was of concern, but we keep learning more and more about the damage caused by UVA. And new, improved forms of protection against UVA keep emerging. Keeping up with these new developments is a worthwhile challenge that can help all of us prevent sun damage.
What is Ultraviolet Radiation?

UV radiation is part of the electromagnetic (light) spectrum that reaches the earth from the sun. It has wavelengths shorter than visible light, making it invisible to the naked eye. These wavelengths are classified as UVA, UVB, or UVC, with UVA the longest of the three at 320–400 nanometers (nm, or billionths of a meter). UVA is further divided into two wave ranges, UVA I, which measures 340-400 nanometers (nm, or billionths of a meter), and UVA II which extends from 320–400 nanometers. UVB ranges from 290 to 320 nm. With even shorter rays, most UVC is absorbed by the ozone layer and does not reach the earth.

Both UVA and UVB, however, penetrate the atmosphere and play an important role in conditions such as premature skin aging, eye damage (including cataracts), and skin cancers. They also suppress the immune system, reducing your ability to fight off these and other maladies.

UV Radiation and Skin Cancer

By damaging the skin’s cellular DNA, excessive UV radiation produces genetic mutations that can lead to skin cancer. Both the U.S. Department of Health and Human Services and the World Health Organization have identified UV as a proven human carcinogen. UV radiation is considered the main cause of nonmelanoma skin cancers (NMSC), including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). These cancers strike more than a million and more than 250,000 Americans, respectively, each year. Many experts believe that, especially for fair-skinned people, UV radiation also frequently plays a key role in melanoma, the deadliest form of skin cancer, which kills more than 8,000 Americans each year.
UVA

Most of us are exposed to large amounts of UVA throughout our lifetime. UVA rays account for up to 95 percent of the UV radiation reaching the Earth’s surface. Although they are less intense than UVB, UVA rays are 30 to 50 times more prevalent. They are present with relatively equal intensity during all daylight hours throughout the year, and can penetrate clouds and glass.

UVA, which penetrates the skin more deeply than UVB, has long been known to play a major part in skin aging and wrinkling (photoaging), but until recently scientists believed it did not cause significant damage in areas of the epidermis (outermost skin layer) where most skin cancers occur. Studies over the past two decades, however, show that UVA damages skin cells called keratinocytes in the basal layer of the epidermis, where most skin cancers occur. (Basal and squamous cells are types of keratinocytes.) UVA contributes to and may even initiate the development of skin cancers.

UVA is the dominant tanning ray, and we now know that tanning, whether outdoors or in a salon, causes cumulative damage over time. A tan results from injury to the skin’s DNA; the skin darkens in an imperfect attempt to prevent further DNA damage. These imperfections, or mutations, can lead to skin cancer.

Tanning booths primarily emit UVA. The high-pressure sunlamps used in tanning salons emit doses of UVA as much as 12 times that of the sun. Not surprisingly, people who use tanning salons are 2.5 times more likely to develop squamous cell carcinoma, and 1.5 times more likely to develop basal cell carcinoma. According to recent research, first exposure to tanning beds in youth increases melanoma risk by 75 percent.

UVB, the chief cause of skin reddening and sunburn, tends to damage the skin’s more superficial epidermal layers. It plays a key role in the development of skin cancer and a contributory role in tanning and photoaging. Its intensity varies by season, location, and time of day. The most significant amount of UVB hits the U.S. between 10 AM and 4 PM from April to October. However, UVB rays can burn and damage your skin year-round, especially at high altitudes and on reflective surfaces such as snow or ice, which bounce back up to 80 percent of the rays so that they hit the skin twice. UVB rays do not significantly penetrate glass.

Facial Toners

Alcohol-free Facial Toner Best for Balancing skin PH

Facial toner should not be confused with astringent, which can strip the skin of its vital acid balance due to higher concentrations of alcohol. Alcohol-free toner helps to instantly restore the natural PH level of your skin. Toning is a step usually taken after cleansing and before moisturizing. It works best to help balance the skin, remove residual cleanser, clear the pores and soothe the skin.

“Alcohol-free facial toner is a vital transition between cleansing and treatment. The Vivoderm toner, for example, is enriched with minerals and natural herbal astringents to purify hydrate and normalize the skin. The grape seed and green tea extracts soothe and tone the skin preparing it to readily receive the maximum benefits of skin care to follow,” reports Dr. Noushin Adhami, Vice President of Vivoderm Laboratories.

Natural facial toner that combines herbal ingredients, like grape seed or green tea extract work more holistically than alcohol-based astringents. Grape seed contains “oligomeric proanthocyanidin” or OPCs showing medicinal and pharmacological properties against oxidative-caused cellular stress. Radical-scavenging effects have also been reported. The bioflavonoids in grape seed are water-soluble and have antioxidant and ‘adaptogenic’ or stress-resistant properties, which help defend against a number of negative environmental factors, including smoke, radiation and chemicals. Green tea extract has been reported act as a protective agent of skin from ultraviolet light.

What all this means is, in order to achieve optimal health, your skin needs sufficient blood supply, hydration, moisture, oxygen and thickness. The natural facial toner is also a complementary part of the anti-aging prevention tools. Facial toner should promote skin health and vitality by toning the skin and retaining the skin’s natural moisture.

The Miracle of Skin

Your skin is the largest organ in your body. If you stretched it out, it would cover about 20 square feet. It weights about 15% of our total body weight. Just like your heart and lungs, it’s a living, breathing part of your body to perform specific tasks. While the obvious reason for skin is to make us look more appealing then a giant sac of organs, it has many functions. Your skin protects your inner workings from the sun’s rays and infection. It insulates your body from heat and cold, repairs itself, and is aware of potential danger through the senses your sense of touch. It is the breeding ground for your blood vessels, sweat glands, and hair follicles. Trust us, your skin does a lot.

Your skin is made up of three layers: The lowest layer of skin is a layer of fatty material known as the subcutaneous layer. On top of that rests the dermis, which contains your nerves, hair follicles (when blocked, are the primary causes of acne), sweat glands, blood vessels. Finally, on top of the dermis is the epidermis, which is the outside layer of your skin that you can touch and feel.

The Layers of human skin

Now, most people do not know that epidermis is made up of three layers too! The outer layer of the epidermis is actually made up of dead skin cells. We lose around 30,000 dead skin cells per minute! There is a middle layer, and finally, an inner layer where new skin cells are produced. Your body is always regenerating itself. That’s why we heal when we get cuts. As your skin cells age, they move their way to the top layer. They begin to die out on this journey. What they lose in functionality as a cell, they make up for in toughness. The trip from a new cell to a dead skin cell takes about 2-4 weeks.

Anti-aging Tips

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. Read more

Ayurveda for Acne and Rosacea

Many of you may be curious, what is Ayurveda and how’s it going to help my acne?

The word Ayurveda translates to “the science of life” (Ayru – life and Veda – science). Ayurveda has brought true health and wellness to millions of individuals throughout the ages with simple changes in daily living practices. Incorporating just a few of these proven methods into your lifestyle can bring about radical changes in your life.
It is currently considered a form of complementary and alternative medicine (CAM) within the United States of America, but this ancient art of healing has been practiced continuously for over 5,000 years.
Where Ayurveda differs is in its approach. Unlike other treatment methods, Ayurveda is a comprehensive, holistic system that uses a variety of therapies in an attempt to bring about fundamental change in a person’s lifestyle.
Ayurveda states that each person is unique, exhibiting a distinct energy pattern that is a combination of physical, mental and emotional characteristics. These energies manifest themselves within three doshas, or regions within the body. The three doshas and their perceived locations are vata (colon), pitta (small intestine), and kapha (stomach).
There are more than 20 types of Ayurvedic treatments. These include herbs, nutritional changes, healing oils, massage therapy, meditation and breathing exercises, yoga and other forms of exercise, as well as inducing a person to sweat, move his or her bowels, or even vomit to cleanse the body of toxins.
According to Ayurveda, ojas is the source of the body’s immunity and the subtle substance that gives healthy skins it’s natural glow. When ojas is depleted, the immune response is weak and the skin becomes lifeless. Low ojas and low immunity result from the same cause: an overload of physical, chemical or psychological stress. Ayruveda describes this overloaded condition as an imbalance of the three doshas, and seven dhatus (or body tissues).
For example, acne rosacea is a blood disease and therefore originates in the second tissue. Whether the stressor is the wrong food or an undigested emotion, it takes a couple of weeks from the time the stress occurs for this type of type to break out. Cystic acne, on the other hand, is a disease of the fat tissue–or fourth dhatu-and takes as long as three to four weeks to appear on the skin. Cancer, a disease of the bone marrow and reproductive tissue –the sixth and seventh dhatus, may exist in the body as long as seven years before being discovered.
The basic premise here is one that western medicine is only now beginning to recognize–that every organ, tissue and cell in your body, are directly connected to each other. The skin and the mind form from the same embryonic tissues in the womb. Our skin can be seen as our second brain and the mirror of our thoughts and emotions. What you eat or drink can affect your mind as equally as how you think or feel can affect your body. This is experiential fact, for any of you who may have enjoyed too much alcohol at one time or felt your stomach turning the last time you were nervous or upset.
Ayurvedic practitioners believe that they must first identify which of a person’s doshas are out of balance before suggesting treatment methods. Symbiotically, whatever substance is absorbed into the skin will have an effect on the individuals’ body tissues and vice versa.
That said, there are some specific treatments that many recognize as effective treatments for skin conditions. For starters, regardless of the skin condition, Ayurvedic practitioners suggest staying hydrated. Ayurvedic practitioners believe that water helps to naturally stabilize dry or oily skin. Drinking enough water also helps prevent the loss of moisture through the skin, which helps to promote overall wellness.

Ayurveda also recommends adhering to a daily regimen for proper skin care, including the use of a natural soap and the use of natural skin moisturizers. This is true whether a person has naturally dry skin or suffers from a more serious condition such as psoriasis. The key is to make sure that the moisturizer is, in fact, natural, containing only substances such as aloe vera—a natural antibiotic that many believe is particularly helpful in the treatment of many skin conditions. Unfortunately, many commercially available moisturizers contain preservatives and other chemicals, and do not fully absorb into the skin, instead remaining on the surface and sometimes clogging pores as a result.

In addition to proper hydration and skin care, Ayurvedic medicine has identified three natural supplements that appear to help treat a wide range of skin conditions—neem, haemafine syrup and khadir. All three of these are widely prescribed to treat acne, psoriasis, and eczema, although many believe they can be used to treat any skin condition. The tree stem, root, and bark of neem, a large evergreen tree, have antibacterial properties. It is used in supplement form to treat skin conditions. In addition, many Ayurvedic soaps contain neem extract. Haemafine syrup is a natural solution made up of more than a dozen herbs. It is used as a remedy for all types of skin diseases through its natural blood purification properties. Khadir, also known as the acacia catechu herb, is another natural blood purifier used to treat skin conditions.

Besides supplements, some Ayurvedic sources also suggest that a person with a skin condition receive an abhyanga, a traditional Ayurvedic massage that uses herbalized oils to draw toxins out through the skin.
