Still skeptical about the whole light-therapy-mask thing? Maybe you'll feel better knowing that this travel-size LED light (and the MMSkincare line in general) was created by board-certified and NYC-based dermatologist Ellen Marmur, who, as I can personally attest, is not about the bullsh*t in skincare. The hands-free LED light comes with nine (!) eight-inch lights, plus a rechargeable battery, so you can prop it up on your desk and do your treatments while working, eating, reading, whatever.
