Blue light and screen time: what the science says about your skin
Based on current research, blue light from phones, laptops and TV screens has not been shown to harm your skin in everyday use. Screens give off far less blue light than the sun. The evidence is stronger for sunlight: its visible light, including blue light, can worsen pigmentation such as melasma, particularly in people with medium to darker skin tones. Research on screens is still limited.
