Today, many people spend hours in front of these screens. Because of this, concerns about blue light and your skin are growing. Recent studies show that blue light can speed up skin aging. As a result, your face may look older faster if you use screens a lot. In this blog, we will explain how blue light affects your skin and what you can do to protect it.

Because we use these devices daily, our skin gets exposed to blue light more than ever before.

As a result, it may cause:Increased production of free radicals, which harm skin cellsBreakdown of collagen, leading to wrinklesChanges in skin color, such as dark spots
Because of these effects, blue light skin damage is now a real concern. Over time, too much screen time and skin aging go hand in hand.

For example, research published in the Journal of Investigative Dermatology found that blue light can cause more skin pigmentation than UVA rays. Another study in the Journal of Cosmetic Dermatology showed that blue light exposure increases free radicals, which speed up aging. While more research is needed, experts agree that digital devices skin health is an important topic. The World Health Organization and dermatology groups now warn about blue light skin damage.
