RealSimple.com: Beauty Myths Debunked

Shaving and Wrinkles

Myth 3: Shaving will make your hair grow back darker and thicker.
"Hair that hasn't been cut grows to a point," says Heather Woolery-Lloyd, a dermatologist in Miami. "It's widest at the base and narrowest at the tip." When you shave a hair, you cut it at the base. The widest part then grows out, and the hair appears thicker. But shaving doesn't change the width, density, or color of hair.

Myth 4: Putting Vaseline on your face nightly will prevent wrinkles.

thick salve on religiously to stay youthful-looking, but that doesn't mean you should. "Petroleum jelly is the strongest moisturizer there is because it forces oils into the skin and prevents them from evaporating," says Paul Jarrod Frank, a dermatologist in New York City. As the skin ages, it loses its ability to retain moisture, and skin that's dry looks older. "Petroleum jelly can make wrinkles less apparent because it's adding moisture to the skin, which softens lines, but it can't actually prevent aging," Pinski says. Only a cream with a proven active ingredient, such as retinol, can stave off wrinkles. Plus, petroleum jelly is so greasy that it can create other problems, including breakouts.
