How to avoid damaging your skin from the blue light when taking selfies

Evita que la luz azul de tus selfies dañen tu piel

You’re probably an expert at taking selfies and finding the best angles. But did you know that excessive exposure to phones without proper protection could damage your skin just like the sun? Find out why and how to avoid it.


Spending more time working from home, in front of the computer, or making videos as an influencer could be a good break for the skin. However, dermatologists like Dr. Leyda Bowes, Medical Director of PIEL ETERNA, often see patients who show dark spots and deterioration in their skin, similar to those produced by excessive sunlight. How is it possible? Well, that happens because we spend more time exposed to electronic screens, which emit light that can cause more problems for our skin than we imagine.


Blue light

Blue light is a type of light emitted mainly by the sun. However, there are also other sources, such as digital screens, LED light fixtures, and fluorescent lighting (1). All of which are now massively used every day in the last decades, which is why their effects are more noticeable.


Keep in mind that this light itself is not bad. It has both positive and negative effects, depending on the intensity and time of exposure. For example, blue light helps us see what's on our screens when the sun's brightness is too intense. But one of the negative effects is that excessively using electronic devices that emit it at night, such as cellphones, can confuse the brain, simulating that it is daytime, which causes melatonin production, the hormone that regulates sleep.


Regarding the skin, it can also help when used in small quantities and at low intensity. Some studies show that in this way, it can help prevent skin diseases (1). However, research has also shown that longer, higher-intensity exposure can:

  • Damage skin collagen
  • Cause wrinkles
  • Increase pigmentation


Studies show that it can even cause DNA damage, cell and tissue death, skin lesions, eye damage, skin barrier damage, and photoaging. (1)


How to protect the skin?


1. Use sunscreen for sunlight and artificial light

In addition to limiting the time of exposure to artificial light, especially high intensity, it is essential to take care of the skin daily with protection that contains ingredients that block this harmful light. The RADIANCE Silky Primer Mineral Sunscreen with SPF 42 from PIEL ETERNA protects against artificial lighting from computers and phones to which the skin is exposed daily. It combines powerful physical sunscreens: zinc oxide, which provides superior coverage to protect the skin from ultraviolet rays, and titanium dioxide, which complements this effect and is equally important for blocking UV rays. Additionally, it contains iron oxides, which protect the skin from the damaging effects of artificial lights from computers, phones, and other screens. An additional benefit this ingredient has is that it also covers imperfections, providing a silky, non-greasy texture that can be worn alone or under makeup.


2. Use a good serum high in vitamin C

This step is essential to take care of the skin and reduce the negative effects of blue light, such as dark spots. A serum with a high concentration of vitamin C can neutralize free radicals caused by this light. The ZELMA Brightening Serum, from PIEL ETERNA, contains a very high concentration of vitamin C, with skin whitening power that helps even out its tone. In addition, it has antioxidants and rescue minerals, which decrease when having emotional stress.

Anyone can use this serum, both male or female, with normal or sensitive skin, morning, and night, for best results.
