With so much focus on protecting skin while in the sun, many assume safety indoors. But if you use a phone, tablet or any electronic device, your skin might suffer from blue light damage. Blue light is part of the visible light spectrum that has a very short, high-energy wavelength. While 40% of it comes from the sun, 60% comes from electronic devices. Consumers are gradually becoming aware of the risks, but of the 40,000 skin care products launched last year, just nine claimed blue light protection.
