Welcome to Camp Sundown


The Xeroderma Pigmentosum Society

Celebrating 25 years of Empowering People with UV-Sensitivty

Research for Students


What is XP? How does it affect people? Imagine that you had to put on a hooded jacket, gloves, faceshield and hat every time you went outside to keep the sun from blistering your skin. XP is a rare disease that exhibits extreme light sensitivity and puts patients at great risk for hundreds of skin and eye cancers cancers. Learn  more.

Camp Sundown


Camp Sundown began in 1995 as one family's dream to give their daughter a "normal" childhood camp experience. It has grown into an annual gathering of XP kids, a foundation for their families and leading researchers to share experiences, build friendships and learn from each other. A camp for the "Children of the Night." Learn more.



The Xeroderma Pigmentosum Society runs a number of programs including education, fundraising, and outreach to benefit those affected by XP around the world. This non-profit foundation has no paid staff positions, benefiting from the generosity of volunteers and donors. There are many ways to get involved. Learn more.



News stories have helped to educate about XP. People affected by extreme sun sensitivity look just like everyone else, until blisters or freckles, cancers begin to appear. Parents don't know why their baby cries when they go outside. Children don't understand why the sun burns so painfully. We hope through more stories like these and work through the Xp Society, there will be a greater understanding and awareness about XP. Read more.

Harvest Moon Camp

was a wonderful event! A relaxing long weekend to enjoy with friends learning new games like spot-it, swimming, showing off the new shirts, painting pumpkins and making creepy hands, visiting the Davenport Farm, eating fun, great meals, and making secret huddles to plot the Thriller show. We had visits from Dr. Moy, Dr. Ellen, and Dr. Hillary. Last campfires and songs of the year, big hugs and laughter. Thank you to our donors, sponsors, volunteers and camper families willing to travel so far.
