Sunscreen really does prevent wrinkles!

Sunscreen really does prevent wrinkles!

Posted on June 4, 2013

Daily use of sunscreen can prevent wrinkles and slow the aging of the skin, according to a new study published in Annals of Internal Medicine.
The researchers looked at 900 Australian adults younger than 55 (mean age, 39), and randomized them to four treatments:

– daily broad-spectrum sunscreen (SPF 15+) plus beta carotene supplementation,
– daily sunscreen plus placebo,
– discretionary sunscreen plus beta carotene, or
– discretionary sunscreen plus placebo.
In this case, “discretionary” meant “just do what you always do”.After 4.5 years’ follow-up, only the group that used sunscreen daily showed no increase in photoaging. Compared with discretionary sunscreen users, daily users were 24% less likely to have increased photoaging. Beta carotene use did not appear to make a difference.
In addition, the authors note that small increases in photoaging also correlate with increased risk for skin cancer.  They note: “A reduction in the highly prevalent aging changes among middle-aged adults by regular application of sunscreen will therefore be associated with cosmetic benefit … and reduced risk for skin cancer.”
Since our weather patterns here are similar, Floridians would be wise to take note!
