Making Sense of Sunscreen Products

January 17, 2010 by admin · Leave a Comment 

Most people are understandably confused when it comes to choosing a sunscreen because of the baffling array of available choices. Common questions about sunscreens include

* How high should the SPF be?

* Should it block UVA or UVB?

* Does it matter whether it is a gel, cream, or spray?

* Should it be water-resistant or waterproof?

SPF stands for sun protection factor. The SPF numbers on a product can range from as low as 2 to as high as 60. These numbers refer to the product’s ability to screen or block out the sun’s burning rays. The SPF rating is calculated by comparing the amount of time needed to produce sunburn on protected skin to the amount of time needed to cause a sunburn on unprotected skin. The higher the SPF, the greater the sun protection. However, it is a common mistake to assume that the duration of effectiveness of a sunscreen can be calculated simply by multiplying the SPF by the length of time it takes for him or her to suffer a burn without sunscreen, because the amount of sun exposure a person receives is dependent upon more than just the length of time spent in the sun. The amount of sun exposure depends upon a number of factors including the length of exposure, time of day, geographic location, and weather conditions.

The sun’s rays contain different wavelengths of ultraviolet (UV) light. The two types of UV rays that pass through the earth’s atmosphere and cause damage to the skin are UVB and UVA. UVB rays are the primary cause of sunburn and affects the outer layer of skin.

The strength of UVB radiation depends upon the time of day, season of the year, and geographic location. UVB rays are most intense from 10 a.m. to 2 p.m. and are stronger in summer, at higher altitudes, and closer to the equator.

Unlike UVB rays, which do not penetrate glass, UVA rays can travel through window glass and damage the deeper layers of the skin. Both UVA and UVB light contribute to age-related changes in the skin such as wrinkles, freckles, age spots, and prominent blood vessels. Both UVA and UVB exposure raise the risk of skin cancer.

Sunscreens can be broadly classified into two categories: chemical sunscreens and physical sunscreens. Chemical sunscreens absorb UV radiation while physical sunscreens act by physically blocking it. Chemical sunscreens can be UVA or UVB absorbers. Many sunscreens have a combination of ingredients and may contain both physical and chemical sunscreens.

Physical sunscreens are good blockers of both UVA and UVB radiation. The two most common physical blockers of UV radiation are titanium dioxide and zinc oxide. Examples of chemical sunscreens include:

* PABA (para-aminobenzoic acid): Rarely found in modern preparations, PABA was an early chemical sunscreen that often induced sensitivity reactions.

* PABA esters (glyceryl, padimate A and padimate O): These newer preparations have fewer side effects than the original PABA.

* Salicylates (homosalate, octyl salicylate)

* Cinnamates (cinoxate, octyl methoxycinnamate or octocrylene): Octocylene is a cinnamate with both UVA and UVB absorbing properties.

* Benzophenones: These can absorb both UVA and UVB rays.

* Ecamsule (Mexoryl) is a potent UVA blocking compound.

Since both UVA and UVB radiation can be damaging, an ideal sunscreen provides protection from both types of radiation. The SPF system measures only the degree of protection from UVB rays. No rating system exists that measures the degree of protection from UVA exposure.

Most experts recommend reading the list of ingredients in a sunscreen to see if it has broad-spectrum (UVA and UVB) coverage. Many products labeled as “broad spectrum” or “UVA blockers” do not adequately block UVA rays. A good broad-spectrum sunscreen should contain avobenzone, ecamsule (Mexoryl), titanium dioxide, or zinc oxide for significant UVA protection.

Whether you choose a lotion, stick, gel, or cream sunscreen depends largely on your skin type and personal preference. Oil-free gels are good solutions for facial skin prone to breakouts, and sprays may make application to the back and shoulders easier.

“Water-resistant” sunscreens should retain their protective ability for at least 40 minutes in water. Those labeled “waterproof” should protect the skin for 80 minutes in water.

The American Academy of Dermatology recommends using a broad-spectrum sunscreen with an SPF of at least 15 on a daily basis throughout the year. An important note is that no sunscreen can be effective unless it is properly and frequently applied. About 1 ounce (5-6 teaspoons) of sunscreen is recommended to cover the entire body. Further, sunscreen must be reapplied every two hours when staying outdoors for a prolonged period of time.

Baby Sun Skin Care for the Summer

June 5, 2009 by admin · Leave a Comment 

The hot days of summer are getting more intense with every year. Especially if you’re in the Northeast where we have a a sun-driven heatwave. Regardless of what zone you live in, smart skin protection is the best medicine to keep your child skin safe in the sun.

You probably remember your first sunburn and maybe even your latest one because it’s so easy for adults to splash sun screen on their kids, and forget to put it on themselves.  As you know, infant skin burns much more easily than adult skin. That’s why it’s important to take extra care with infants and toddlers when they are out in the sun.

UV Rays

It’s no secret that the depletion of the ozone layer has changed our way of thinking about sun protection. There is no doubt that the sun rays today are stronger and more intense those of 60 years ago.

Extended exposure to ultraviolet rays from the sun causes skin damage and premature aging. However, it is important to remember that sunlight is important to good health. Small amounts of ultraviolet rays stimulate the body to produce vitamin D, an essential vitamin for good health. Deficiency of vitamin D is a serious health concern and leads to conditions such as rickets in children. In short, moderate sun is healthy, but sunburns are not.
Too much exposure to sunlight can result in immediate pain and long-term harm. Without getting too scientific here, sunburn is caused by extended exposure to the sun’s ultraviolet rays. Short-term results can be pain, allergic reactions and heat stroke.  In the long term, researchers say that victims of sunburn can suffer from lupus, cataracts, premature skin aging and an increased risk for skin cancer.

Skin Type
A person’s sensitivity to the sun is related to his or her skin type. An individual’s skin type determines how easily that person can become sunburned. Those with fair skin, freckles, blue eyes and/or blonde or red hair sunburn much easier than those with darker skin, eyes and hair.

Children younger than 6 years of age and adults older than 60 years are at an increased risk for sunburn. Skin type affects how easily you become sunburned. People with fair or freckled skin, blond or red hair, and blue eyes usually sunburn easily. Your age also affects how your skin reacts to the sun.

Young Skin is Sensitive
The skin of children under age 6 and adults over age 60 is more sensitive to sunlight. Premature aging from sunlight can affect people of all skin shades. A sunburn can be caused by the sun or by artificial tanning sources, including tanning beds and sun tanning lights. You can even get sunburned not only in the summer, but also in the winter.

Here are some basic sun care tips:

  • Sunlight is most intense between 11 a.m. and 3 p.m., so avoid exposure during these times
  • Avoid exposing babies younger than six months of age to direct sunlight
  • Dress your child in light, loose clothing that covers the whole body
  • Use a sun hat or bonnet, and keep the sunshade up on the stroller up This is good advice for young babies
  • Toddlers often resent the restrictions of clothing, and feel it’s best to run around naked. For these free little spirits, use a gentle, natural sunscreen with organic ingredients, available at your health food store
  • Slather on sunscreen generously and reapply, even on cloudy hazy days
  • Never put sunscreen too close to children’s eyes or on their hands, as they might rub their eyes and cause irritation
  • Keep your child and yourself well hydrated. Keep water bottles handy or nearby
  • Bring a beach umbrella to the beach or park(if there are no shady trees nearby)

Have fun in the sun this summer, but do take care of the tender skin.

A Few Basic Facts About The Sun and Our Skin

May 22, 2009 by admin · Leave a Comment 

Here are some straight forward facts to consider on the topic of sun protection. The sun radiates two different rays that are cancer causing, UVA and UVB. The UVA ray is longer and it affects the skin much deeper than a UVB ray. The UVB ray is the one that gives you sunburn. Both can cause skin damage and skin cancer.
When you buy a sunscreen and you look for a sun proof factor (spf), you are looking for protection from the UVB ray. The thing is, most sun blocks are only keeping out the UVB. So, you can have sunscreen on, thinking you are safe, but still get skin cancer from the UVA rays.

SPF, an abbreviation for sun-protection factor, is a number such as 15, 30, or 50 that indicates how long a topical sunscreen remains effective on the skin. A user can determine the duration of effectiveness simply by multiplying the SPF by the length of time it takes for him or her to suffer a burn without sunscreen.

Basal Cell Carcinoma is a common form of skin cancer with almost 1 million cases each year in America. Treatment includes a procedure to remove the cancer, typically by cutting out the affected area or treating with a topical chemotherapy. If left untreated, the cancer will continue to grow. Individuals who have been diagnosed with basal cell carcinoma need sun protection to minimize UV exposure.

Bottom line – the sun is our friend.  We need it and it is wonderful for our spirits and our health. Enjoy it but safely and in moderation.

Facts and Myths About Sun Care Protection

March 27, 2009 by admin · Leave a Comment 

Sun protection has become a way of life for individuals, who are intent on keeping their skin healthy, and avoiding wrinkles and leathery skin. Getting sunburn repeatedly can increase your chance of getting skin cancer. Melanoma in children has been increasing each year! So it is important for us all to take a practical approach and properly use natural sunscreen and develop healthy skin care habits. Surprisingly, not everyone knows how to apply sunscreen. Only a small percent of the population uses sunscreen protection and only half of those people apply sunscreen correctly. In addition, regardless of the SPF or what the label says, sunscreens must be reapplied every 80 minutes or less. Sunscreen users mistakenly believe that high Sun Protection Factor (SPF) sunscreen products will protect them all day with one application, when in fact; all sunscreens must be reapplied regularly.

Two Sunscreen Myths

Myth: Sunscreen provides total sun block.

Truth: No sunscreen blocks 100 percent of Ultra Violet (UV) rays. SPF 15 can protect against 93 percent. SPF 30 protects against 97 percent. SPF 50-60 shuts out 98 percent. The higher the SPF the more harsh chemicals are in the product.

Myth: An SPF 60+ sunscreen provides double the protection of an SPF 30 sunscreen.
Truth: This is exactly why the FDA is putting a cap on high SPFs. SPF 30 provides skin with 97% protection, where as SPF 60 provides skin with 98-98.6% protection. There is less than 1.6% difference in protection factor. A SPF 60+ needs more chemicals to achieve a higher SPF, potentially putting more toxins in your body.

The real confusion to consumers has been what a product can do and can’t do. There are a number of sunscreen products are available on the market today. The trick is to become educated! Do you believe that just because sunscreens are labeled “sweat proof” or “waterproof” that they are? Currently, the FDA is banning the word “waterproof.” Now the term, “water/sweat/perspiration resistant” is accurate, however; this only means the sunscreen offers SPF protection after 40 minutes of water exposure. The term, “very water resistant” gives 80 minutes of protection. So to be safe, use this basic rule of thumb: re-apply, re-apply, and re-apply! For people who don’t have a lot of time, especially parents, a trend today has been to use aerosol sunscreens because they find them easier to apply. However, people may not be effectively protecting their skin! While being applied, aerosol sunscreens can lose much of their protection during the transfer from the bottle onto the skin. This is because not all of the molecules land on your body.
