 Sunscreens

Choose your Sunscreen carefully!
 

How do you choose a Sunscreen that is right for you?

With so many products out on the market it is difficult to make the right choice.

  • Use a SPF 30 or greater year-round for all skin types, considering that fair-skinned people who sunburn easily may want to select a product with a higher SPF (sun protection factor)

  • Choice of oils, gel, sprays, cream or lotion
    • Consider that most oils do not contain sufficient amounts of sunscreen (SPF2)
    • Gels tend to sweat off and need frequent reapplication
    • Spray, while easy to apply can be difficult to ensure complete coverage
  • Consider a Broad Spectrum Sunscreen that provides protection from both UVA and UVB protection

  • Look for UVB absorbers such as Salicylates and Cinnamates.
  • Remember some people are sensitive to PABA (para-aminobenzoic acid) used as a UVB protectant and this can stain clothing. Newly refined PABA esters (glycerol PABA, Padimate A and Padimate O) are now on the market.
  • Your sunscreen should also protect against UVA radiation, these rays penetrate deeper into the skin and are suspected of being the culprits in premature aging and wrinkling of the skin.



Do you know the difference between a sunscreen and a sunblock?

Sunscreen can be classified into two major types: chemical and physical.

Chemical sunscreens usually contain UVB absorbing chemicals and more recently contain UVA absorbers as well. These ingredients act as filters and reduce ultraviolet radiation penetration to the skin. These sunscreens often are colorless and maintain a thin visible film on the skin. 

 Physical Sunscreens, most often referred to as sunblocks, are products containing ingredients such as titanium dioxide and zinc oxide which physically block ultraviolet radiation (UVR). Sunblocks provide broad protection against both UVB and UVA light.  Micronized zinc oxide, micronized titanium oxide, Parsol 1789® 

A combination of two or more is generally used. Zinc oxide is the single most effective broad spectrum ingredient. White zinc oxide is a physical UV blocker while micronized (transparent) zinc oxide is a UV absorber.
Both white and micronized titanium oxide are physical blockers. There are drawbacks which include; messy to use, visible and it does not wash off easily.  However, if you are looking for a natural product that provides a high degree of protection then you will want to consider these types of products.


What is SPF?

SPF stands for "Sun Protection Factor."   The sunscreen product label provides the SPF factor ranging from 2 up to 50 and this refers to the ability of the product to screen or block out the sun's harmful rays.  As an example, using a SPF 15 sunscreen you can be in the sun 15 times longer than you could without sunscreen before burning.  However, SPF protection does not increase proportionally with an increased SPF number. An SPF of 15 will absorb 93% while an SPF of 34 absorbs 97%.

  • The SPF rating on sunscreen only refers to the products ability to screen or block out UVB rays.  Currently there is no FDA-approved rating system to measure the UVA protection levels.

The rating is based on using 1 ounce of product per full body application. 
So if your bottle of sunscreen is 4 ounces that means you would use about ¼ of that bottle to get that rating each time you use it all over!


Are you using enough sunscreen?

For a majority of us, the answer is no.  To provide effective coverage you will need to apply an ounce ( size of a small shotglass) of sunscreen to exposed skin.

  • Currently, sunscreens are measured by their sun protection factor (SPF) which is only a measure of UVB protection. Make sure your sunscreen says it is broad-spectrum and also protects against harmful UVA rays.

  • Statistically, most people only use about 1/3 of the recommended amount of sunscreen. For example, if you were to apply an SPF 30 sunscreen to your skin, the actual volume of sunscreen that is typically used is only equal to an SPF 10.

  • Remember that water, humidity, and sweating decrease the effectiveness of sunscreen and numerous reapplications are necessary.


How to determine if "waterproof" or "water resistant" is for you?

Firstly, you should consider the sort of outdoor activities you participate in.  If you enjoy team sports or water activities and spend a lot of time in and around the pool, beach or exposed to the sun etc you may want to look for a "waterproof" sunblock.  How well sunscreen stays on the skin after swimming, water sports or perspiring is just as important as the SPF level. 

If you choice of outdoor recreational activities includes hiking, hunting etc. and you are able to seek shade you may feel more comfortable with a "water resistant" product.

The FDA considers a product "water-resistant" if it maintains its SPF level after 40 minutes of water exposure. A product is considered "waterproof" if it maintains its SPF level following 80 minutes of exposure to water.  


When is it appropriate to use sunscreen?

The answer is simple... everyday, and year-round! 

Make the use of sunscreen a part of your daily routine, and apply before you leave your home.

Any time you are likely to spend 20 minutes or more exposed to the sun you should use a sunscreen.  Most people will receive this amount of sun exposure while performing routine activities. Sunscreen can be applied under makeup and there are also cosmetic products available that contain a sunscreen for daily use. 

Because sun protection is the principal means of preventing premature aging and skin cancer, many regular moisturizers now contain a SPF 15. Sunscreen used on a regular basis actually allows some repair of damaged skin.

Because the sun's reflective powers are great - 17 percent on sand and 80 percent on snow - don't reserve the use of these products for only sunny summer days. Even on a cloudy day 80 percent of the sun's ultraviolet rays pass through the clouds. Skiers beware, ultraviolet radiation increases 4 percent for every 1,000-foot increase in altitude.


How much sunscreen should you use and how often should you apply it?

You should apply sunscreen to your dry skin 30 minutes BEFORE going outdoors. Pay particular attention to your face, ears, hands and arms. Apply sunscreen liberally using one ounce to completely cover your body. Be careful to cover exposed areas, a missed spot could mean a patchy, painful sunburn.

Lips get sunburned too, so apply a lip balm that contains sunscreen with SPF 15 or higher.

Sunscreen should be applied in the morning and reapplied after swimming or perspiring heavily as they begin losing effectiveness after 80 minutes in the water, so reapply sunscreen before this time, especially if you have towel-dried for maximum protection.


Protective   Clothing

What is sun protective/ultraviolet light clothing?

  • Normal summer clothing does not fully protect your skin from the sun.  They rate less than SPF 8 when wet.

  • The clothing uses fabric to protect your skin from damaging UVA & UVB rays and can be worn instead of using sunscreen on those areas.

  • But don't forget to wear sunscreen on the uncovered areas like the neck and ears.

  • The fabric is rated according to an Ultraviolet Protection Factor ("UPF") similar to "SPF" for Sunscreen and is usually greater than SPF 30.



What is the difference between UPF and SPF?

  • UPF is like SPF except UPF rates fabric protection against both UVA and UVB.

  • A garment with a UPF of 50 only allows 1/50th of the UV radiation falling on the surface of the garment to pass through it.  In other words, it blocks 49/50ths or 98% of the UV radiation.  Factors such as tighter knit or weave, thickness, and dark color can increase UPF. 


What are the benefits of sun protective clothing?

Sun protective clothing.....

  • Does not need to be reapplied
  • Does not wash off
  • Is long lasting - can be washed and dries quickly
  • Has no known skin reactions from UV-absorbing compounds in the fabrics
  • Is a "rash guard" against surfboard and body-board rashes
  • Saves money! The clothing actually reduces the need for expensive sunscreens and lotions and pays for itself quickly
  • Is available in fun and innovative designs from many manufacturers
  • Check to see if the product comes with a endorsement from a dermatologist, or skin cancer organization

Why is sun protection important?

Skin Cancer is growing at alarming rates.  2007 Statistics from the American Cancer Society show that:

  • 1 in 5 Americans will develop skin cancer at some point during their lifetime
  • 5 or more sunburns during your lifetime doubles your risk of developing skin cancer
  • Sun protection is especially important in children because sunburns in early life can lead to skin cancer in adulthood
  • 80% of lifetime sun damage occurs in childhood (prior to the age of eighteen)*
  • Melanoma is the second most common cancer in women ages 20-30; 1 person dies almost every hour (every 62 minutes) from this disease
  • Both ultraviolet A (UVA) and ultraviolet B (UVB) rays can cause skin cancer. You can protect your skin and eyes in many different ways including sunscreen, seeking the shade, hats, sunglasses and sun protective/ultraviolet light protective clothing.

   

*Kids rarely follow proper sunscreen application either when they play outdoors, ride bikes, go to recess or play on the playground.

Love the skin you're in ...wear sunblock!
