Acne. It can make you feel uncomfortable and can be downright painful, but a new Canadian invention could make clear skin a reality for even the longest sufferers.
Some call it the "zit zapper," but a more technical description of Tanda is a portable light wand lined with little blue LED lights that actually kill the bacteria that cause acne.
"In each troubled area you want to do it for three minutes," says Tanda inventor John Kennedy.
"Then you go to the next area ... it beeps every 30 seconds so you know where to move it around."
Tanda not only promises to get rid of mild to moderate acne, but prevents it from coming back. It costs $295 and is available at Holt Renfrew as well as your dermatologist's office.
"It sounds ridiculous," admits user Jean Stilwell. "But for me it's a miracle, it's the only thing that works."
