UV Radiation and Skin: A New Way to See the Damage

Ever wondered how the sun's rays affect your skin? Well, scientists have found a cool way to see the impact of UV radiation on our skin. They used a technique called digital holographic interferometry (DHI). This method helps us visualize how UV rays change the skin's surface and stiffness. This is important because UV rays come from more than just the sun. They are also found in electronic devices and artificial sources used in medicine, industry, and cosmetics. This means we are constantly exposed to them. By using DHI, researchers can create pseudo-three-dimensional (3D) images of the skin. These images act as biomarkers, helping to understand how UV rays affect our skin.The key here is that these biomarkers show changes in skin surface displacement and stiffness values. This information is crucial for assessing the health risks posed by UV radiation. The cool thing is that DHI can help us see these changes more clearly. This could lead to better ways to protect our skin from the harmful effects of UV rays. It's like having a superpower to see the invisible damage caused by the sun and other sources of UV radiation. This research is a step forward in understanding how UV rays affect our skin and finding ways to keep us safe.
