Only about 10-15 percent of dermatologists nationwide have UV cameras, but the number is rapidly rising, according to the vice president of the nonprofit Skin Cancer Foundation in New York City, David Goldberg, M.D.

According to recent studies, despite the well-known risks of extensive sun exposure, people are failing to exercise caution in protecting themselves against sun damage.  A recent University of California, San Diego, study found that students were more likely to use sunscreen after seeing UV photos revealing unseen damage to their skin.

Melanoma is the fastest growing form of cancer, but experts believe it is hard to grasp the long-term effects of sun damage since it can take years before visible signs appear.  The use of UV photographs could be a way to bridge the disconnect that can occur among young people and help them realize sun damage is a cumulative effect. 

In addition to increased skin cancer risks, damage from UV rays can also cause wrinkles and age spots.
