So what makes this anti-acne blue light shield the best new tool to add to your skincare routine? It’s a one-step, at-home acne treatment. The anti-acne blue light helps to reduce and treat blemishes and repair skin with triple the power of the original mask. The wavelength of the blue light helps kill acne-causing bacteria while also working to improve the environment of skin health. And the wavelength of the red light helps to promote blood circulation, increase metabolism, produce collagen, and aid in the anti-aging process. Together, the powerful anti-acne LED light targets current acne and prevents future breakouts. Light on, acne off! Plus, since it’s a hands-free device, it’s perfect for multitasking. We like to call it “multitasking masking,” because you can pamper and treat your skin while doing pretty much anything, like cooking, walking your dog, folding laundry, talking on the phone with a long-distance friend, or simply watching TV. The options are endless.
