Dermatology Health Initiative

Hershey Community Pool Lifeguards sun protection program - lifeguards are outfitted with sun protection shirts

2019-2020 featured a new dermatology community health initiative, led by Laurie Krnjaic, CRNP, in sponsoring a T-shirt design competition on sun protection for children.

The fourth through sixth graders at Bear Creek Elementary were invited to draw a sun protection superhero. After a judging process of their own peers and art teacher, Bear Creek sent the final nine drawings to the dermatology clinic where staff chose the final three. A panel of three judges followed to choose the grand prizewinner and two runner-ups. 

The grand prizewinner had their design placed on the sun protection t-shirt for their entire class. Students in the three classes received t-shirts with the winning design imprint and sunscreen samples. Congratulations to the Grand Prize Winner, 5th grader, Wyatt Joiner!

Penn State Dermatology at Hershey Gardens

Penn State  Dermatology partnered with Hershey Gardens to help protect the community from the dangers of sunlight. We've donated fifty umbrellas for visitors to use, free-of-charge, during their visit to the Gardens. Their specialized fabric protects visitors from the sun’s harmful rays (UVA and UVB) while enjoying the picturesque scenery.

Skin Cancer and Aging

Skin cancer is the most common type of cancer in the United States. The sun’s ultraviolet (UV) rays are associated with 90 percent of all non-melanoma skin cancer and 65 percent of melanomas. A person’s risk for melanoma - the most serious form of skin cancer - doubles if he or she has had five or more sunburns. More than 100,000 Americans are diagnosed with melanoma annually. In addition to skin cancer, up to 90 percent of visible changes commonly attributed to aging are caused by the sun.

Sun Safety

  • Schedule outdoor activities in the early morning or late afternoon. Seek the shade between 10 a.m. and 4 p.m., when the sun is most intense. Use your umbrella!
  • Apply and reapply a full ounce (two tablespoons) of sunscreen to the body, including a nickel-sized dollop to the face.
  • Cover-up with UV-blocking clothing, including a broad-brimmed hat and sunglasses.

Why not have shade whenever you want it?

Get your own Sun Umbrella!

  • • UV protection
  • • Fifteen degrees cooler than in the sun
  • • Double-canopy design
  • • Water-repellent fabric

The umbrellas have specially treated fabric that protects the skin from both UVA and UVB rays, forming a virtually impenetrable barrier from the sun.

Contact our office at 717-531-6049 to see how you can purchase one of our sun umbrellas.
