2 At the conclusion of this presentation, participants will:  Understand the effect of UV rays on skin  Be able to both define SPF and know the minimum recommended value for SPF  Identify risk factors for sun damage  Identify ways to reduce the risk of sun damage  List things that minimize risk of sun damage

3  Why is sun protection important?  What are the benefits of sunlight?  What are the risks?

4  How many of you use a form of sun protection when at the:  Beach?  Park?  Afterschool or afterwork activities?  Walking the dog?

5 1. If you use plenty of sunscreen, you can stay in the sun as long as you'd like. A. True B. False

6 2. Which of the following surfaces reflects ultraviolet rays? A. Snow B. Sand C. Ice D. Water E. All of the above

7 3. You don't need to protect or cover your skin on cloudy days. A. True B. False

8 4. Wearing white during hot weather protects you from sun damage because light-colored clothing reflects light, rather than absorbing it. A. True B. False

9 5. Choose a sunscreen with a sun protection factor (SPF) of at least: A. 5 B. 10 C. 15 D. 30

10 6. Darker lenses on sunglasses offer better protection from ultraviolet rays than do lighter sunglass lenses. A. True B. False

11 7. Sunbathing or sun tanning once in a while won't hurt your skin. A. True B. False

12 8. The darker your skin color, the less you need to worry about sun protection. A. True B. False

13  Sunlight  Total spectrum of the Electromagnetic Radiation given off by the sun  Electromagnetic Radiation  The full range of wavelengths that makeup light (visible and non-visible)  Light waves are fluctuations of electric and magnetic fields

14

15  Band of sun rays  5% of sunlight that reaches the earth  Reflects off of water, snow, sand and ice  Three types  UVA  UVB  UVC

16  UVA  90% reaches the earth on a cloudy day  Not blocked by window glass  Penetrates light clothing  Penetrates deeper into the skin  Has more long-term effects than UVB

17  UVB  “B” for burn  Cloud cover provides some protection  Intensity varies  Time of day  Season  Altitude  Weather

18  UVC  Most rays are absorbed by the earth’s atmosphere  More dangerous than UVA and UVB  Causes serious damage to DNA

19  Sunburns -- the most common and acute response  Photoaging – the leading cause of skin aging; damage begins as early as in one’s 20’s  Cancer – ultraviolet radiation is a known carcinogen (cancer causing agent)  The effect is cumulative; the more time spent unprotected in the sun over your lifetime, the greater the risks.

20  Skin’s protective sun filter  Natural pigment  Acts as a shield against the sun’s ultraviolet rays  Greater in populations that live in areas with greater sun intensity (Africa, Central America, Indian subcontinent, etc.)

24  The most common form of cancer in the US  1 million new cases are diagnosed yearly  1 in 5 Americans and 1 in 3 Caucasians will develop skin cancer in their lifetime  >90% of all skin cancers are caused by sun exposure  The risk for skin cancer doubles if a person has had 5 or more sunburns

25  Newer high pressure sun lamps can emit UVR in doses 15 times that of the sun  Occasional use of tanning beds almost triples the chance of developing melanoma – the deadliest form of skin cancer; the use of tanning beds before the age of 35 increases the risk for melanoma by 75%  People who use tanning beds are 2.5 times more likely to develop squamous cell cancer and 1.5 times more likely to develop basal cell cancer  On an average day, more than 1 million people in the US tan in tanning salons; 70% are Caucasian women ages

26 Everyone

28  A rating system developed by the FDA to describe the level of sun protection provided by a sunscreen  For example: an SPF of 30 allows an individual to stay out in the sun 30 times as long as without the sunscreen before developing the same reddening of the skin.

29  SPF 15 blocks approximately 93 percent of all incoming ultraviolet rays  SPF 30 blocks 97 percent  SPF 50 blocks 99 percent  AAD and the Skin Cancer Foundation recommend a minimum SPF of 15  Reapply every 2 hours (even on cloudy days), especially after swimming or sweating

30  Broad spectrum providing protection from  UVA  UVB  Apply 30 minutes before sun exposure  Reapply every 2 hours  Reapply immediately after swimming, toweling off or excess sweating  Use 1 ounce each time

31  Physical  Made of zinc oxide and titanium dioxide  Protect against UVA and UVB  Prevent rays from being absorbed  Chemical  Mexoryl protects against UVA and UVB  Avobenzone or Oxybenzone protect against UVA OR UVB  Absorb rays before they can do damage

32

33  Cream formulations  Contribute to destruction of coral reefs due to chemicals  Mineral based sun protection (Colorescience® Sunforgettable) do not have chemicals that affect the environment

34  Window film  Sunscreens with UVA and UVB protection  Sunglasses with UVA and UVB protection  Self tanners  Sun protective clothing and fabric  Makeup, lip balm and moisturizers with a sunscreen  Umbrellas  For more information and to learn more about the “Go With Your Own Glow” campaign go to

35 1. If you use plenty of sunscreen, you can stay in the sun as long as you'd like. False Reapply sunscreen every 2 hours

36 2. Which of the following surfaces reflects ultraviolet rays? A. Snow B. Sand C. Ice D. Water E. All of the above All of the above

37 3. You don't need to protect or cover your skin on cloudy days. False UVA rays still penetrate through clouds

38 4. Wearing white during hot weather protects you from sun damage because light-colored clothing reflects light, rather than absorbing it. False UV rays are still absorbed through lighter colored clothing

39 5. Choose a sunscreen with a sun protection factor (SPF) of at least: A. 5 B. 10 C. 15 D. 30 C. 15

40 6. Darker lenses on sunglasses offer better protection from ultraviolet rays than do lighter sunglass lenses. False Glasses should specifically state that they provide UVA and UVB protection

41 7. Sunbathing or sun tanning once in a while won't hurt your skin. False Sun damage is cumulative over a lifetime.

42 8. The darker your skin color, the less you need to worry about sun protection. False Even darker skin types can get sun damage and skin cancer.
