How Much Sun Is Too Much?

Brianna Linderman and her friends are part of a growing number of teenagers who are "tanmaxxing." They say that they spend hours a day in the sun when the UV rays are the strongest and often don't use any sunscreen. Dermatologists say all that time in the sun can have long-term consequences and can lead to skin cancer and premature aging. Inside Edition arranged for Brianna and her friend Jordan to be checked out at the Ablon Skin Institute in Manhattan Beach, California where D. Alynis Ablon conducted an exam to see if they had any sun damage.
