The blue light effect

The Blue Light Effect: How Electronic Screens Impact Your Skin

In the digital age, screens have become an integral part of our daily lives. From smartphones to computers, we’re constantly exposed to electronic screens. 

Blue light (BL), also known as high-energy visible (HEV) light, is a colour in the visible light spectrum that can be seen by human eyes. These wavelengths of visible and non-visible light are measured in nanometers (nm). 

In general, the shorter the wavelength, the higher the energy1. While most discussions about screen exposure revolve around its impact on our eyes and sleep patterns, there’s growing evidence about another lesser-known side effect: the impact on our skin. In this article, we’ll explore how the blue light from electronic screens can affect our skin’s health and ways to protect ourselves.

what is blue light

Blue light is a spectrum of visible light with wavelengths between 380 and 500 nm. Our main source of blue light during the day is sunlight. However, electronic devices like smartphones, computers, and LED lights also emit significant amounts of blue light.

What is blue lights effect on skin?

Our skin is the body’s primary defence against environmental aggressors. With the rise of electronic devices, it’s now facing a relatively new challenge: blue light. The modern lifestyle, marked by extended periods in front of screens, exposes our skin to an increasing amount of blue light. But what is blue light’s effect on skin? Let’s delve deeper.

1. premature aging

Just as the sun’s UVA/UVB rays have long been known to cause premature aging, emerging research indicates that blue light shares a similar potential to harm. But how?

  • Depth of Penetration: Blue light has the ability to penetrate deeper into our skin compared to UVB rays. This means it doesn’t just affect the superficial layers but reaches the collagen and elastin-rich dermal layers, potentially disrupting these vital structures.
  • Oxidative Stress: When blue light penetrates these deeper layers, it can generate reactive oxygen species (ROS) or free radicals. These unstable molecules damage skin cells’ DNA, proteins, and lipids, leading to premature signs of aging like wrinkles and fine lines.

The 0.1% Retinol + 1% Azelaic Acid + 3% Niacinamide from our Simple Science line is expertly formulated to address the emerging concerns of blue light damage. Blue light delves deeper than UVB rays, reaching collagen and elastin structures in our dermal layers, which could lead to their disruption. Furthermore, its penetration can produce reactive oxygen species, causing damage to skin cell structures and precipitating early aging signs. Trust our formula to help counteract these harmful effects, keeping your skin youthful and radiant.

2. Hyperpigmentation: more than just a tan

Prolonged screen time isn’t equivalent to a sun-tanned vacation, but it does have pigmentation consequences.

  • Melanin Overproduction: Our skin produces melanin as a defence mechanism against various forms of damage. With increased exposure to blue light, there’s an uptick in melanin production. This can manifest as dark spots or uneven skin tone.
  • Persistent Discolouration: Unlike the temporary darkening after a sunburn, blue light-induced hyperpigmentation can be more persistent and harder to treat. This requires targeted skincare regimens or professional treatments.

The Hyperpigmentation Duo of 5% Niacinamide Booster Serum and 14% Azelaic Acid Booster Complex is your answer to the modern-day skin challenges brought about by screen exposure. Extended screen time can amplify melanin production in our skin, leading to dark spots and unevenness. Furthermore, the hyperpigmentation caused by blue light is stubborn, often persisting longer than traditional sun-induced discoloration. Our specially formulated products aim to tackle these issues head-on, offering a solution for maintaining a balanced and radiant complexion.

3. inflammation: The silent fire within

Inflammation is our body’s natural response to injury, but when triggered unnecessarily, it can lead to various skin concerns.

  • Free Radical Surge: Blue light exposure can increase the production of free radicals in the skin. These molecules, in turn, instigate inflammatory pathways, making the skin more susceptible to conditions like redness, rashes, and even more severe conditions like eczema or rosacea.
  • Barrier Dysfunction: Chronic inflammation weakens the skin’s barrier function, making it more susceptible to external irritants, allergens, and infections.

While electronic devices have become indispensable tools in our daily lives, it’s essential to recognize and address their potential side effects on our skin. By understanding these impacts in depth, we can adopt better skincare practices and mitigate the adverse effects of blue light exposure.

The Copper P (Peptide) Concentrate Serum is meticulously crafted to combat the side effects of unwarranted skin inflammation. Blue light exposure can boost free radical production, paving the way for inflammation and potential skin issues like redness and eczema. Furthermore, consistent inflammation compromises the skin’s protective barrier, leaving it vulnerable to external threats. Our serum, enriched with Copper Peptides, helps counteract these problems, promoting a resilient and calm complexion.

how can we protect our skin?

While it’s unrealistic to completely avoid screens, there are steps we can take to minimize the blue light effect:

  1. Screen Filters: Invest in screen filters that block or reduce blue light emission from your devices.
  2. Skincare Products: Many skincare brands now offer products specifically formulated to protect the skin against blue light damage. Look for antioxidants like Vitamin C and E in the ingredients.
  3. Limit Screen Time: Take regular breaks when working on electronic devices and avoid screen usage during the hour before bed.
  4. Wear Sunscreen: Sunscreens with iron oxide are may provide some protection against blue light.

Understanding blue light’s skin hazards allows proactive steps for modern digital era skin health.
