In today’s digital world, most of us spend multiple hours every day on smartphones, laptops, and other screens. This frequent exposure to blue light — the visible light emitted from digital devices — can impact skin health over time. According to the original article, blue light penetrates deeper into the skin compared to some visible wavelengths, causing oxidative stress, inflammation, and structural changes in the skin. These effects don’t happen instantly but accumulate gradually, leading to issues like uneven pigmentation, weakened skin barrier, dullness, and early signs of ageing such as fine lines and loss of elasticity. This phenomenon is often referred to as digital ageing because it stems from modern screen‑centric lifestyles.
