Sept. 21, 2010 -- Sunless tanning has long been promoted as a safe alternative to sunbathing and tanning bed use. Now two new studies suggest the message may be resonating with teens and young adults and even keeping some out of the sun.
The findings also suggest that promoting sunless tanning may be a more effective strategy for reducing skin cancer than trying to convince people who prize a bronzed look simply to stay out of the sun.
“That message has been out there for a long time, but it has done nothing to change people’s perception that tanned skin is attractive,” University of Massachusetts Medical School assistant professor of medicine Sherry Pagoto, PhD, tells WebMD. “When it comes to physical appearance, it is hard to change social norms with a public health message.”
Whether applied at home with a cream or spray tanner or sprayed on in a salon by a professional, sunless tanners essentially dye the dead outer layer of the skin to make it look bronzed. The “tan” lasts up to a week.
The best products contain the active ingredient dihydroxyacetone (DHA), which has been commercially available since the early 1970s, Pagoto says.
Beach-Goers Changed Tanning Habits
In their effort to determine if promoting sunless tanning would change sunbathing habits, Pagoto and colleagues recruited 250 female beach-goers for their study in the summer of 2006.
Half the women received information about the benefits of sunless tanning and the risks associated with UV exposure from the sun or tanning beds. They were also given sunscreen and sunless tanning samples and had UV-filtered photos taken. The photos revealed sun damage to skin not visible to the naked eye.
The other women received none of these interventions, but all the study participants agreed to be contacted for follow-up.
Two months later, women in the intervention group reported sunbathing less frequently and using more protective clothing than the other women.
A year later, the intervention group still reported sunbathing less and using sunless tanning products more often.
Survey of Teen Tanning Habits
In a separate study, researchers with the American Cancer Society asked 1,600 teens about their use of sunless tanning products.
