I can't rave about this mask enough! Red light therapy, near infrared, blue light, green light, ALLLL the lights! Its cordless and rechargeable and it is for the face AND the neck! I can tell a difference when I am not using it. And I can't believe the price!! Its 1/4 of what I paid for my uncomfortable hard mask that isn't even 12 as good as this one! skincare redlighttherapy matureskin perimenopause antiaging
