Treat Acne @ Home • @neutrogena Light Therapy Acne Mask I purchased this Light Therapy Mask by Neutrogena in the hopes of it making it an easy and convenient way to take care of my skin at home. The mask is super easy and comfortable to wear. You can multi-task while wearing the mask, which is actually really cool. It has a red light, which reduces inflammation and a blue light to kill the bacteria. It has a Remote/Activator that has 30 daily treatment sessions. Once the 30 days are used up, then replace the activator. I’m loving this creative and innovative beauty method.
