Hello and welcome to the show. Today, we're diving into one of the hottest topics in beauty: blue light skincare. With our screen time increasing, especially since the pandemic, the cosmetics industry has seen a surge in products claiming to protect our skin from the 'digital ageing' caused by phones and laptops . But what exactly is blue light? It's a high-energy visible light, or HEV, that's part of the visible light spectrum . While our devices do emit it, the sun is actually our greatest source of exposure . The debate is fierce. Some research suggests blue light penetrates skin deeper than UV rays, potentially causing oxidative stress, collagen breakdown, and worsening hyperpigmentation like melasma . However, other studies, including one by major research centre Beiersdorf, argue that the blue light from our devices is negligible and nowhere near enough to cause harm . So, is blue light skincare a necessary shield in our digital age, or just clever marketing? Today, we'll unpack the science, scrutinise the claims, and explore whether you really need to worry about your screen time ageing your skin.
