How Does The Light Of The Mobile Affect The Skin?

The radiation emitted by mobile screens is one of the causes of premature aging. Large changes are generated in the skin that can be avoided. Are you interested in understanding more about it?

Overexposure to light from mobile devices, be they computers or smartphones, can negatively affect skin health. Although it goes unnoticed at first, the light of the mobile causes a damaging impact on the skin that can affect aging.

While it is true that these devices have become part of our daily lives and are almost essential, their misuse has health consequences. What do they cause at the skin level? How to protect yourself from these damages?

What kind of light does mobile emit?

First, let’s remember that mobile light is of an artificial type, with high energy, which is in the same ultraviolet band as sunlight, with its characteristic harmful effects on the skin.

In recent years, with the ease of accessing computers, tablets, smartphones, among other devices, exposure to this type of light has increased. Hence, the concept of ” digital aging ” began to gain prominence.

It not only refers to the effects that these lights cause on the skin but also to their impact on the eyes, the circadian rhythm and the sleep cycle. In studies, this exposure is associated with problems such as insomnia.

Effects of mobile blue light on the skin

The impact of blue light from mobile phones and other devices on the skin varies according to the conditions in which the exposure occurs, such as periodicity, intensity, and duration.

In general, the effects of high-energy visible (HEV) light are believed to be similar to those caused by ultraviolet A and B rays. The manifestations it generates on the skin are called Screen Face. What are the most frequent?

Hyperpigmentation

An article published in The Journal of Investigative Dermatology in 2018 details that blue light from electronic devices generates melanocytes’ activation, responsible for increasing melanin in the skin. This substance rises towards the most superficial layers and causes pigmented macules.

Exposing the skin to the effects of artificial blue light disorganizes the melanogenesis process. It favors the presence of spots, with a higher prevalence in the region around the eyes and forehead.

People who could be more at risk of hyperpigmentation would be those with a high phototype because their cells produce more melanin. Also, people who perform peelings on their faces or pregnant women since their skin is more sensitive in light radiation.

Oxidative stress

According to a study published in the journal Free Radical Biology and Medicine, this light generates an increase in free radicals. It is responsible for accelerating premature aging of the skin, characterized by the loss of elasticity and firmness.

Likewise, the cells and fibroblasts of the dermis are damaged during their activation. When this process fails, the mechanisms responsible for stimulating collagen, whose function is to give the skin smoothness, are altered.

Dehydration

In a study published in Photodermatology, Photoinmunology & Photomedicine, there is evidence about the effects of light emission on the hydration state of the skin and the cutaneous barrier. In particular, it seems to alter the synthesis of the proteins that compose them.

Another research shows that the blue light radiations emitted by the screens of mobile devices alter the normal functioning of aquaporins and keratinocytes, cells that make up the most superficial layer of the skin, that is, the epidermis.

Solar elastosis

The action of radiation generates solar elastosis. The skin becomes more yellow, rough and thicker than usual. These changes are caused by the alteration of collagen and the degeneration of elastic fibers.

All these manifestations generated by overexposure to blue light are included in the concept of «digital aging» and cause premature photoaging.

Taking care of the skin of the mobile light is possible

Today, trying to disconnect from mobile devices is a fantasy. Still, it is possible to take some preventive measures to avoid your light affecting the health of the skin.

The most advisable thing is to add a specific product to the daily routine for protection against blue and environmental light. You should also limit your screen time as much as possible. This, added to the practice of good habits, helps protect the skin from the aforementioned effects.
