Deep Cleaning Faces at the Speed of Sound
You've heard of the sonic toothbrush. Now meet the sonic facial brush, which makers say oscillates so fast it shakes the dirt loose from pores.
Some dermatologists say the sonic brushes vibrate super fast, which makes them better at shaking loose dirt than face washing with hands or manual facial brushes.
The sonic brushes help get rid of blackheads and improves appearance of skin, they say. While the brushes give off sound waves, there isn't yet clear evidence the sound helps with cleaning.

A sonic brush "really vibrates the dirt out of the skin and it doesn't cause irritation," says Tina Alster, director of the Washington Institute of Dermatologic Laser Surgery in Washington, D.C. Dr. Alster has served as an unpaid member of the medical advisory board of one brush maker, Pacific Bioscience Laboratories Inc., Redmond, Wash., but has no financial link to the company.
Adds Bruce Katz, clinical professor of dermatology at the Mount Sinai School of Medicine in New York, "it is particularly useful for people who have blackheads and whiteheads."
The Clarisonic brush head oscillates at more than 300 times a second, says Ken Pilcher, co-founder of Pacific Bioscience, which was acquired earlier this month by L'Oréal SA. The company claims its brush cleans six times better than hand washing, makes pores look smaller and generally makes skin look better. The Clarisonic ranges in cost from $119 for the small, travel-size Mia to $225 for the deluxe Plus model, which includes a larger body brush.

A less-expensive option is the Nutra Sonic sold by Nutra Luxe MD LLC of Fort Myers, Fla., oscillates about 300 times a second, according to company president, Peter von Berg. The brush ranges from $79 to $159, depending on the model. Both the Nutra Sonic and the Clarisonic are rechargeable.
In an abstract published in 2007 in the Journal of the American Academy of Dermatology, a company-funded, 10-person study found the Clarisonic was "significantly more effective" in removing makeup than using soap and fingers. The study used fluorescent makeup on subjects' faces, which were then cleaned by a technician using a Clarisonic for half the face and just fingers for the other half; a mild cleanser was used on both sides. The study measured the amount of pixels of fluorescence remaining after cleaning. Pacific Bioscience says the results translate to six times more makeup being removed.
There are currently no published studies on the Nutra Sonic.
I tried the Clarisonic for a week, washing half my face with the brush and the other half with a washcloth for 30 seconds each, using a mild cleanser on both sides. By the second use, my pores looked noticeably smaller on the Clarisonic side on close inspection. By the end of a week, the Clarisonic side felt smoother to the touch than the washcloth side.
A number of electric facial brushes without a sonic feature are popping up on store shelves and claim to offer deep-cleaning benefits. The Olay Professional Pro-X from Procter & Gamble Co., which costs about $30, has a battery-powered brush head that makes about five or six rotations a second, according to P&G. Its unpublished internal tests have found the brush is six times more effective than cleaning using hands, the company says.
The electric brushes get mixed reviews from dermatologists. Dr. Alster says she is concerned the rotating motion is more likely to grind dirt into the skin and create tiny "microcuts," which could serve as a portal for bacteria.
Dr. Katz says the electric brushes or even small manual brushes are fine "as long as you don't do it too vigorously." But he says they are likely not as good as the sonic ones at dislodging dirt.
P&G says it did a "torture test" of the Pro-X involving using the device with a harsh cleanser, at the highest-speed setting for up to two minutes, twice a day for a month on 62 women. There was no evidence of facial cuts, infections, redness or irritation, the company says. P&G recommends using its brush daily for just a minute with a mild cleanser. Laura Joannes - wsj.com
