Blue light is a part of the visible light spectrum that has the ability to damage your skin by accelerating skin’s aging processes, can cause cell shrinkage, and can cause pigmentation issues. Sunlight is the largest source of blue light, which is why it is so important to wear sunscreen daily, no matter how sunny it is! Blue light can also emit from electronic device screens (smart phones, laptops, etc.), so we also recommend purchasing blue light shields to cover your screens and keep your skin protected!
