We spend billions of dollars trying to erase our wrinkles. But the solution could be a simple product most of us sometimes use.
A new study published in the Annals of Internal Medicine reveals the not-so-secret ingredient now shown to slow skin aging: sunscreen. And the evidence is convincing.
The four and a half year study was done in Australia- where the sun is strong – really strong.
Researchers looked at nearly a thousand adults age 55 and younger, divided into four groups:
The beta carotene didn’t help. It had no overall effect on skin aging.
Before this study, dermatologists thought sunscreen cut down on skin aging. But it had only been proven in hairless mice. Now we know better.
Vanity aside – wearing sunscreen has another benefit: it’s an important tool in the fight against skin cancer, including melanoma, the deadliest form.
So: wear it regularly, and when you’re in the sun, reapply often.
