Sunscreens, UVB and UVA Rays

With summer lurking just around the corner, it’s almost time to tie up that new bathing suit, fire up the grill, and most importantly, slather on the sunscreen. The importance of sun care escalates as knowledge of skin cancer increases in the United States, and the National Cancer Institute estimates that there are more than one million new cases of skin cancer in 2009 alone. Still, loyal sunbathers and frequent beach-goers are able to enjoy some fun in the sun thanks to the vast array of sunscreen available. Sunscreens are available in several forms, including lotion, sprays, ointments, and sticks, and are often labeled with a Sun Protection Factor (SPF), which can range from 2 to 50. The higher the SPF, the more sun protection, and most dermatologists recommend using a sunscreen with an SPF 15 or higher.

Sunscreen protects the skin from harmful UVA and UVB rays from the sun, and too much exposure to these rays can cause sunburn and wrinkles. Long term sun exposure can lead to cancer, which is the most common type of cancer, according to the American Cancer Association. Most sunscreens contain zinc oxide, which as the ability to filter UVA and UVB rays to protect the skin. Zinc oxide has been used in skin products for many years and can be used with all skin types.

UVradiation, a known carcinogen, can have a number of harmful effects on the skin. The two types of UV radiation that can affect the skin—UVA and UVB—have both been linked to skin cancer and a weakening of the immune system. They also contribute to premature aging of the skin and cataracts (a condition that impairs eyesight), and cause skin color changes.

UVA Rays

UVA rays, which are not absorbed by the ozone layer, penetrate deep into the skin and heavilycontribute to premature aging. Up to 90 percent of the visible skin changes commonly attributed to aging are caused by sun exposure.

UVB Rays

These powerful rays, which are partially absorbed by the ozone layer, mostly affect the surface of the skin and are the primary cause of sunburn. Because of the thinning of the ozone layer, the effects of UVB radiation will pose an increased threat until the layer is restored in the latter half of the 21st century.

The following table from the FDA lists these ingredients and includes information regarding the type and amount of ray protection that they provide and their class.

Is a Suntan Healthy?

Just remember, there is no such thing as a healthy suntan. Any change in your natural skin color is a sign of skin damage. Every time your skin color changes after sun exposure, your risk of developing sun-related ailments increases.

Skincare Dollars and Sense

Many consumers are frustrated by skin care products that don’t do what they claim to. Worse still is investing in an expensive yet ineffective cream or treatment only to discover the cheapest drug-store brand would work just as well. In a world of hyper-consumerism, false advertising and a plethora of products from which to choose, how do you choose the good from the bad?

There are some great products on the market that can genuinely improve your skin’s appearance and help your skin look smoother, more radiant, and youthful. But, there are literally thousands of products to choose from and unless you spend hours a day researching beauty products, it’s difficult to find the one of the few that actually produces real results and eliminates years of aging from your face and body.

Not only should a quality skin product help reduce bags under, and fine lines around, the eyes, but it should even out coloration inconsistencies caused by age spots and other unwanted pigment concentrations.

In a marketing-rich world of super models and glamorous actors, many will understandably spend any amount of money to make themselves look better or younger. Cosmetic surgery and skin care is a multi-billion dollar industry.

As the law of supply and demand proves, the higher the demand for youth and beauity, the more manufacturers will rush to provide the solution. Many times this rush results in the creation of an inferior product with little to no research and development to back it.

All of the money goes into the marketing of the product. On the surface everything looks great. The bottles and jars that the creams come in look appealing. The magazine advertisements are glossy, complete with a youthful looking model or a well known celebrity who doesn’t even really use the products.

You can’t really blame these companies. When you are spending a fortune paying for marketing, whether it be on the product containers, magazine, radio, and TV ads, royalties paid to celebrities and models, you have to charge a lot of money for your products or you’re going to lose money.

On the other hand, this doesn’t mean you and I have to fall for these types of marketing schemes. After all, these companies aren’t going to encounter any shortage of people who will open their wallets and purses to purchase their products anytime soon. The reality is most people simply won’t take any time to research products and understand what ingredients work and what ingredients are actually bad for your skin!

Treatment for Dry, Sensitive Skin

If you suffer from dry, cracked or sensitive skin – skin that easily reacts to chemicals and temperature fluctuations - then keeping your skin hydrated is essential. If you live in a humid climate where natural moisture is more prevalent, then you are halfway there to better skin. On the flip side, if you live in a high-altitude or desert climate, artificially creating humidity in your home may be the second best option. Since many of us can’t just pick up and move to a new seaside location, using a humidifier in your home or bedroom while you sleep can do wonders for your dry, cracked skin.

While drinking more water will help hydrate your skin to a degree, it isn’t the cure-all for sensitive skin issues. However, the water you use to bathe is very important. Bathing with hard water (which contains increased amounts of calcium) can contribute to dryness and redness. Reverse osmosis water filters will help convert hard water to soft water, if it fits in your budget, it could be a consideration. Water temperature also matters. Dermatologists warm that very hot water temperatures, such as 104 degrees F, can dry out your skin and lead to redness. Gentle hydrotherapy, meaning moderate temperatures with little fluctuations are best for your skin type.

When choosing a special spa treatment, do so with care. Be wise in selecting spa and beauty treatments like exfoliating massages, loofahs, acid-peel facials, and hot steam rooms, which can all strip oils from sensitive, dry skin. Scalding temperatures, intense treatments, running from hot saunas into wintry snow is good for those with resilient skin - not for you. For those with especially sensitive skin, even perfumed bath oils and massage products can be irritating. Aromatherapy massages may be counterproductive if the oils used cause any form of burning or redness. Even getting a manicure or pedicure can cause hyper-reactions when the acetones in nail polishes and removers are irritating.

If you have had serious reactions to spa treatments in the past and need a gentler alternative, consider thalassotherapy. Thalassotherapy was developed in seaside towns in Brittany, France during the 19th century. Based on the belief that the properties of seawater have beneficial effects upon the pores of the skin, trace elements of magnesium, potassium, calcium, sodium, and iodide found in seawater are believed to be absorbed through the skin. The therapy is applied in various forms, as either showers of warmed seawater, application of marine mud or of algae paste or the inhalation of sea fog. Spas make hot seawater and provide mud and seaweed wrapping services.

Very popular throughout Europe, thalassotherapy treatments are used for relaxation, stress management, muscle and skin restoration, and to fight cellulite. If you cannot afford the actual spa treatments, home products containing seaweed or algae can also be effective in hydrating dry, sensitive skin. Another great option to provide more oil distribution to dry skin is massage. Massage is also great for eczema. A recent dermatological study at the University of Miami showed that children with severe dry skin were treated with moisturizer and massage therapy improved more compared to those who were not massaged and were treated with moisturizer alone.

So these are simply guidelines to use when choosing products and treatments to help alleviate your dry skin conditions. As with all hydrotherapy treatments, it is important to limit your immersion in the water to less than one hour so as not to impair the skin barrier. And when purchasing products, always be sure to read the ingredient list for potential irritants.
