Your phone's secret attack: How HEV light is aging your face and disrupting sleep

High-energy visible (HEV) light, commonly known as blue light from smartphones and tablets, contributes to premature skin aging through mechanisms similar to solar radiation. Combined with poor posture during device use and the suppression of sleep hormones, long-term gadget dependency affects both physical appearance and systemic health. Impact on Skin and Pigmentation HEV light penetrates deep into the dermis, triggering the production of free radicals. This process damages collagen and elastin fibers, resulting in a loss of skin elasticity and the formation of fine lines. While blue light does not cause acute burns like ultraviolet (UV) radiation, it can provoke persistent pigmentation, particularly in individuals prone to melasma. "Visible blue light can trigger oxidative stress and increase pigmentation with prolonged exposure. However, it is important to understand that the dose of radiation from the sun remains significantly higher than from a phone screen," explains therapist Anna Kuznetsova in an interview with Pravda.Ru. She notes that those prone to skin spots may benefit from cosmetics containing antioxidants.
