If you thought staying indoors all day was enough to protect your skin from the premature ageing caused by UVA and UVB rays, well, think again — skincare experts have added another culprit to the mix. “Blue light or high energy visible light (HEV) is a short wavelength violet-blue light that is emitted by various screen devices such as mobile phones and artificial light sources such as LED bulbs. Blue light penetrates the skin much deeper than ultraviolet rays and triggers pigmentation, photosensitivity, and premature aging,” explains Dr Niketa Sonavane, a dermatologist and founder of Ambrosia Aesthetics.
