A new study shows that light from phone and computer screens may harm the skin more than sunlight. Health experts now recommend using sunscreen even when staying indoors with electronic devices.
Screens have become a key part of daily life. From smartphones to laptops, people spend many hours in front of screens every day. But this habit comes with risks. One of the most serious is damage to the skin.
Dr. Sidhant Mahajan, a skin specialist, says that screens emit a type of light called blue light. This light can reach deeper layers of the skin compared to sunlight. He warns that blue light speeds up skin aging by damaging collagen and elastin—proteins that keep the skin firm and youthful.
The study found that using screens for 6 to 10 hours daily increases the risk of skin damage. Dr. Mahajan advises people to use sunscreen that contains iron oxide and vitamin C. These ingredients help protect the skin from harmful blue light.
Even without direct sun exposure, long screen time can cause early wrinkles and uneven skin tone. This research highlights the need to protect the skin not only outside, but also indoors in front of screens.
