Blemish Buster

THE CLAIM This space-age-looking light machine aims to obliterate the bacteria that cause redness and inflammation. After dabbing on the anti-microbial gel, you gently press the triangular head to your trouble spots and leave it on for six minutes.
THE EXPERT SAYS "It's best for adult acne, focused in one or two spots," says N.Y.C. dermatologist Alyson Penstein. "If you use it the moment you feel a pimple coming on, the device can lessen its size. But "cystic acne is more complicated than just killing bacteria," she adds. "It requires prescription treatment."
OUR VERDICT The device worked, but it's more labor-intensive than slapping on an acne cream. It took 20 minutes to treat spots on our forehead and chin.
