How Much Sun Is Too Much?

Briana 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 Briana and her friend Jordyn to be checked out at the Ablon Skin Institute in Manhattan Beach, California where Dr. Glynis Ablon conducted an exam to see if they had any sun damage.
