Some Dermatologists See a Sunscreen Revolution

May 19, 2006 — -- Three girls lying in the harsh midday sun on Miami Beach giggled nervously when asked why they were exposing their skin to the sun's harmful rays.

"We need a good tan," said Cristina Bengochea.

"For graduation tomorrow," added Nataly Diaz.

This weekend they will graduate from high school and they are determined to look glamorous.

"It's in style to have a tan nowadays," said Cristina. "Because all the celebrities have it."

And that's the problem. People know that the sun's rays are harmful, but they can't resist. They also know that sunscreen helps.

Tamara Vanhell, who was soaking up the scene with her friend Brian Mascia, said that although she didn't mind sunscreen, "it's kind of a hassle."

As the summer suntan season begins, there is new hope -- sort of. A number of new products promise a revolution in a bottle, and dermatologists are enthusiastic about some of them.

"The big news is that there are products now that both stay on the skin longer and more importantly continue to work longer," said Dr. Allan Oseroff, dermatology chair at both the Roswell Park Cancer Institute and the University at Buffalo.

The most promising new products are sunscreen lotions containing an ingredient called Helioplex. It is being called the most important advance in sunscreen in 20 years.

Existing sunscreens effectively block UVB rays, but their UVA protection breaks down in less than two hours. Helioplex blocks those UVA rays for twice as long as anything that has come before. Neutrogena is one of the first manufacturers to put Helioplex products on the market in the United States.

"Helioplex is a great product," says Dr. Rachel Herschenfeld, a dermatologist in Massachusettes. "Most of the ingredients that protect us from UVA break down really soon after you go out in the sun. Helioplex prevents that from happening."

Dermatologists are less enthusiastic about new sun protection pills meant to be taken daily along with sunscreen lotions. Makers of a supplement tablet called the SunPill say it helps protect your skin against sun damage. But ABC News found that the medical community isn't buying that claim.
