(HealthDayNews) -- Americans spend billions of dollars each year on products that promise to erase wrinkles, lighten age spots and eliminate dry or red skin.
But the simplest and cheapest way to keep your skin healthy and young looking is to avoid too much direct sun, according to the National Institute on Aging.
Sunlight is a major cause of the skin changes we think of as aging. As your skin ages, it becomes thinner and loses fat, so it looks less plump and smooth. Veins and bones become more prominent, and your skin can take longer to heal.
Staying out of the sun can help postpone these changes. Although nothing can completely undo sun damage, the skin sometimes can repair itself. So be sure to slather on the sunscreen, even during the winter.
