What is phototherapy? Is that like when I got blitzed at the office Xmas party and xeroxed my boobs? No, phototherapy is using photons or light waves to treat your skin for common conditions like mild acne. Is that like laser treatment? No. Not at all. Phototherapy uses blue and red LED lightbulbs to treat acne. The blue light kills acne-causing bacteria. The red light eases inflammation under the skin. What does that mean? It's a powerful natural treatment for acne similar to what dermatologists use in their offices. This product is the absolute best on the market.
