Acne breakouts occur when hormonal changes cause our sebaceous glands to produce excess sebum (oil), P. acnes bacteria feed on the sebum and multiply, clogged pores trap the multiplying P. acnes bacteria and white blood cells move in to fight off the invading bacteria -the result, a pimple.

414nm blue LED light has been clinically proven to kill acne-causing P. acnes bacteria, clearing existing blemishes and preventing future outbreaks.
