How to protect your skin from blue light damage?

Blue light is everywhere. It’s the type of light that comes from the sun, but also from our digital devices, such as computers, smartphones, tablets, and LED lights. While blue light has some benefits, such as regulating our circadian rhythm and boosting our mood, it also has some drawbacks, especially for our skin.


According to dermatologists, blue light can penetrate deeper into our skin than UV rays, and cause oxidative stress, inflammation, and collagen breakdown. This can lead to premature aging, hyperpigmentation, dullness, and sagging of the skin. Moreover, blue light can disrupt our sleep quality, which can also affect our skin health.


So, what can we do to protect our skin from blue light damage? Here are some tips:


  • Limit your screen time. The best way to avoid blue light exposure is to reduce the amount of time you spend in front of your digital devices. Try to limit your screen time to no more than two hours per day, and avoid using them at least one hour before bedtime. You can also use apps or settings that filter out blue light from your screens, or wear blue light blocking glasses.

  • Apply sunscreen. Sunscreen is not only important for protecting your skin from UV rays, but also from blue light. Choose a broad-spectrum sunscreen with SPF 30 or higher, and reapply it every two hours. Look for ingredients that can block or reflect blue light, such as zinc oxide, titanium dioxide, iron oxide, or lipochroman.

  • Use moisturizer. Blue light can dehydrate your skin, so it’s important to keep it moisturized. Use a hydrating moisturizer that suits your skin type, and apply it twice a day, morning and night. Look for ingredients that can boost your skin’s barrier function, such as ceramides, hyaluronic acid, or squalane.

  • Use serum. Serum is a concentrated product that can deliver active ingredients to your skin. Use a serum that can counteract the effects of blue light, such as antioxidant, anti-inflammatory, or brightening agents. Look for ingredients such as vitamin C, niacinamide, retinol, or resveratrol, and apply them before your moisturizer.

  • Get enough sleep. Sleep is essential for your skin’s regeneration and repair. Aim for seven to nine hours of quality sleep every night, and make sure your bedroom is dark, cool, and quiet. You can also use a silk pillowcase, which can reduce friction and prevent wrinkles.
