Daily use of sunscreen has been scientifically shown to prevent aging.
A study by the Queensland Institute of Medical Research followed 900 young and middle-aged men and women for four and a half years and found that those who wore SPF 15+ sunscreen most days had no detectable signs of aging.
“This has been one of those beauty tips that you often hear quoted, but for the first time we can back it with science. Protecting yourself from skin cancer by using sunscreen regularly has the added bonus of keeping you looking younger,” said lead author and epidemiologist Adele Green.
Silicone moulds were taken from the backs of hands of all participants and the start and end of the study to assess sun damage.
Half of the participants who had used sunscreen most days on their face, arms and hands showed no signs of aging, states the study published in the Annals of Internal Medicine. And they had 24 per cent less skin aging than those who used sunscreen only some of the time.
Researchers concluded that daily use of broad spectrum sunscreen — which protect against both UVA and UVB rays — slows the process of aging and prevents skin cancer.
All of the study’s participants were under age 55 to ensure that photo-aging rather than chronological aging was the major factor in any skin changes. That allowed researcher to conclude that up until middle age, it’s not too late to use sunscreen to lessen the impact of the sun’s rays on your skin.
