The Dangers of Digital Aging & How to Protect Yourself

In today’s digital age, we are constantly surrounded by screens and devices emitting blue light. From smartphones to laptops, these gadgets have become an integral part of our daily lives. However, as technology advances, so does our understanding of its potential impact on our health, including its damaging effects on our skin. Jamachi Plastic Surgery sheds light on the negative effects of blue light and provides you with tips to protect your skin in this digital age.

How Does Blue Light Contribute to Digital Aging?

Blue light is a high-energy visible (HEV) light that emanates from the sun and various electronic devices, such as smartphones, computers, and LED lighting. While natural blue light during the day helps regulate our sleep-wake cycle and enhances our mood, excessive exposure to artificial blue light, especially in the evening, can lead to adverse effects on our skin. Blue light at night stimulates the brain and tricks it into thinking it’s daytime. This leads to sleep deprivation, which actually accelerates the aging process.

Sitting in front of a screen for 60 minutes or more negatively affects our skin. A 32-hour work week in front of a computer monitor exposes you to the same amount of harmful light energy as 20 minutes in the midday sun.

What Are the Negative Results of Too Much Screen Time?

  • Premature Aging: Prolonged exposure to blue light can accelerate the aging process by generating free radicals, which damage collagen and elastin fibers – the building blocks that maintain skin’s elasticity and firmness. This can lead to the development of fine lines, wrinkles, and sagging skin, making you look older.
  • Tissue Damage: Studies have found that the blue light from screens causes oxidative stress — a process that occurs when the ratio of antioxidants to free molecules in the body is unbalanced. This presents itself as tissue damage: hyperpigmentation, wrinkles or dark spots.
  • Hyperpigmentation: Studies suggest that blue light exposure can trigger the overproduction of melanin, causing hyperpigmentation and dark spots on the skin. This can be especially concerning for individuals with already existing skin conditions like melasma.
  • Skin Barrier Disruption: Blue light can impair the skin’s natural barrier function, making it more vulnerable to external aggressors like pollutants and bacteria. As a result, the skin becomes prone to inflammation, sensitivity, and a heightened risk of acne breakouts.
  • Sleep Disturbance: Excessive exposure to blue light, particularly from screens before bedtime, can disrupt our sleep patterns. Blue light particularly at night disrupts the production of melatonin which is a natural hormone that regulates circadian rhythms hence sleep. Moreover, poor sleep negatively impacts the skin’s ability to regenerate and repair itself, leading to a dull and fatigued complexion. Specifically, collagen, a protein that maintains skin elasticity and smoothness, is produced during a period of deep sleep, so if deep sleep is interrupted, premature aging can result. 
  • ​​Inflammation and Redness: Blue light exposure can cause inflammation in the skin, leading to redness and irritation. It may worsen conditions like rosacea and acne, making them more difficult to manage. 

How Can You Protect Yourself from Digital Aging? 

While avoiding all electronic devices isn’t feasible in this digital era, plastic surgeons Dr. Dare V. Ajibade and Dr. Chukwuemeka Onyewu say there are steps you can take to safeguard your skin from the harmful effects of blue light:

  • Limit Screen Time: Reduce the time spent in front of screens as much as possible, especially during evening hours, to minimize blue light exposure before bedtime.
  • Use Blue Light Filters: Invest in blue light filters for your devices or enable blue light filters (some, like turning on “night mode” on your phone, are free).
  • Choose Skincare with Antioxidants: Use protective skincare products daily, especially products rich with vitamin C, vitamin E and antioxidants to combat free radicals generated by blue light exposure. Wrinkles aggravated by blue light can also be smoothed using various aesthetic treatments.
  • Apply Sunscreen All Day, Every Day: Don’t forget to apply a broad-spectrum sunscreen with at least SPF 30 daily, as it offers protection against both UV and blue light.

As we embrace technology, it is crucial to be mindful of its potential impact on our skin. Blue light, although not as notorious as UV rays, can pose serious threats to our skin health, leading to premature aging, hyperpigmentation, and compromised skin barriers. By understanding the risks and adopting proactive measures, such as limiting screen time and using protective skincare, you can maintain a radiant and youthful complexion even in the face of digital exposure.
