If you don't know a penta-peptide from an antioxidant and frankly don't care -- you just want your gator-dry legs to be soft and silky-smooth -- look no farther than your kitchen. The answer lies in that bottle of safflower oil sitting on the shelf. This polyunsaturated oil, beloved by cardiologists for being good for your heart, is just as good for your skin, but from the outside in.

The oil, which is pressed from the seeds of spiky yellow safflowers, is a super moisturizer. "That's because it's very high in linoleic acid, a fatty acid that skin normally makes to keep its moisture level up and barrier function intact," says New York City dermatologist Amy Wechsler, MD, RealAge's skin expert. Since our body's linoleic acid production gets sluggish as we age, it helps to replace it from the outside.
