Dana L. Oliver, Beauty Editor, StyleList, and her mother, Shirley B. Oliver

Ma has one of the brightest smiles I've ever seen, and whenever she flashes those pearly whites, the chaos in my life turns calm. So it is only natural that the woman I admire the most's best beauty lesson is to simply smile.

She's shown me that this friendly form of expression not only makes me attractive, but it makes me appear more youthful -- which is key to keeping my colleagues guessing at my age.

Besides, my bold lipstick turns heads when I wear it with my gap-toothed grin.
