What form of light is emitted from electronic devices and reportedly penetrates the skin more deeply than UV rays?

• A. Infrared light
• B. Visible light
• C. High-energy visible light
• D. Gamma rays

Answer: (C)

High-energy visible light is emitted from electronic devices such as screens and LED lights, and it is known for its ability to penetrate the skin more deeply than ultraviolet (UV) rays. This form of light falls into a specific range of the visible spectrum, often referred to as "blue light," which has higher energy compared to other wavelengths of visible light.

Research has indicated that high-energy visible light can reach deeper skin layers, potentially contributing to oxidative stress and photoaging effects. Unlike UV rays that primarily affect the upper layers of the skin, high-energy visible light can influence deeper dermal structures by generating reactive oxygen species (ROS), which impact skin health.

Understanding the unique properties of high-energy visible light is critical for comprehending skincare implications, particularly with the increased use of digital devices. This highlights the importance of protective measures, such as applying sunscreen or using skincare products that combat oxidative stress from blue light exposure.
