MONDAY, June 3 (HealthDay News) -- In the never-ending search for the fountain of youth, scientists have looked everywhere under the sun. But a group of Australian researchers now report that the answer lies out of the sun.
Regular daily use of sunscreen appears to significantly slow the process of skin aging among middle-aged men and women, they say.
The finding stems from 4.5 years spent tracking sunscreen use and its ultimate impact on skin quality among more than 900 men and women under the age of 55.
"This has been one of those beauty tips you often hear quoted, but for the first time we can back it with science," said study co-author Adele Green, lab head and senior research fellow with the Queensland Institute of Medical Research at Royal Brisbane Hospital. "Protecting yourself from skin cancer by using sunscreen regularly has the added bonus of keeping you looking younger."
"And the study has shown that up to middle age, it's not too late to make a difference," added Green, who also suggested that sunscreen use is likely to similarly benefit those over 55, though her team did not specifically assess a potential benefit among older users.
The findings appear in the June 4 issue of the Annals of Internal Medicine.
Perhaps surprisingly, the authors point out that, to their knowledge, their current effort is the first rigorous scientific exploration of the potential protective effect of sunscreen on skin aging in people.
Green and her team looked at data collected in a study on skin cancer prevention conducted between 1992 and 1996 in Nambour, Australia.
The authors focused on 903 mostly fair-skinned men and women who were under the age of 55, under the assumption that skin aging in that age category would be brought on primarily by so-called "photoaging," as opposed to simply growing older.
