How LEDs Can Help Your Acne

Dor those with acneic skin, decreasing that bacteria ensures there is less of it to interact with that oil and pore "sludge." One novel way to do this is with blue LED-light treatments, also called photodynamic therapy (PDT). Here's how it works: There is a blue-light wavelength that has been identified to reduce p. acnes, and with it acne lesions. This wavelength has been incorporated into treatments to kill that p. acnes. "Blue LEDs eradicate the bacteria that cause inflammation during breakouts, reduce pore size, stabilize oil production, and promote healthy cell growth," raves celebrity aesthetician Kate Somerville, who's been using IPL treatments at her famous skin clinic since 2004.
