“I wanted to be cute, to look cute, but I had these ugly lines in between my eyebrows and on my forehead,” says Stephanie Torres, 19, of New York. “So I asked if I could get Botox. My mom paid for it. It was like a little birthday present.”

Torres, who went under the needle at age 18, is one of many teens and early 20somethings who are turning to Botox in an effort to not only smooth existing furrows, but fend off the aging process itself.
