  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 Goals

  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 Let’s see what you know (or don’t)

  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. True False

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

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

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

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

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

  14. Electromagnetic Spectrum

  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 Ultraviolet Rays

  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. How does Ultraviolet Radiation affect the skin?

  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.) Melanin

  21. Skin type

  22. 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 Skin Cancer

  23. 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 16-49. Tanning Beds

  24. Everyone Who is at risk?

  25. EVERYONe

  26. 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. SPF -- Sun Protection Factor

  27. 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 Sunscreen

  28. 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 Sunscreen Recommendations

  29. 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 Sunscreens

  30. 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 Sunscreens

  31. 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 www.skincancer.org Skin Cancer Foundation Recommends

  32. 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 Let’s see what you know

  33. 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

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

  35. 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

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

  37. 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
