Having visible tan lines and sunburn marks used to be a dreaded part of summer that everyone hopes to avoid. But now, having a even tan is so last summer. Sunbathers across the nation are sharing photos of their burns on social media with the hashtag #SunburnArt to show off their elaborate tan lines.

Sunburn Art is exactly what it sounds like - a sunburn meticulously crafted into a shape on your back, stomach or legs, creating a tatoo-like appearance. Covering a specific area of skin to block it from the sun, social media users are then sharing their end results of flowers, names, the Batman logo and a Mona Lisa. But Sunburn Art is also exactly as dangerous as it sounds.

"While it may be entertaining, it is intentionally exposing your skin to harmful ultraviolet radiation," Dr. Thomas Rohrer, a dermatologist, told CBS News.

According to the American Cancer Society more than 73,000 cases of Melanoma, or skin cancer, will occur in 2015. The risk factors include being easily sunburned, severe sunburns in the past, older age and exposure to ultraviolet radiation from sunlight or tanning beds among many others.

"To increase your skin cancer risk for the purpose of innovative body art is not recommended," Dr. Debbie Palmer, a dermatologist in Westchester, New York says according to the NY Daily News. "Sunburn's effects are long-lasting."

Dermatologists have made it clear this is one social media trend you don't want to follow. Make sure your skin is protected this summer by using sunscreen daily.
