We live in an age of ubiquitous screens, from smartphones and computers to tablets and televisions. These devices emit blue light, a high-energy visible light (HEV) that can have harmful effects on our skin. In this article, we will look at the consequences of blue light on skin health and explain why it is essential to adopt specific protection.
What is blue light and where does it come from?
Blue light is a part of the visible light spectrum, characterised by a short wavelength and high energy. It is present in daylight, which makes it necessary for our well-being (such as regulating our biological clock). However, our digital screens and certain artificial lighting sources (such as LEDs) also emit large quantities of blue light.
Why is blue light harmful to the skin?
While blue light may seem harmless, its cumulative effects on the skin can be significant. Here are some of the main consequences of prolonged exposure to blue light:
1. Cellular oxidation and premature ageing
Blue light generates free radicals in the skin, leading to oxidative stress. These free radicals can damage skin cells and accelerate skin ageing. The loss of collagen and elastin leads to wrinkles, fine lines and premature sagging.
2. Pigmentation disorders
Studies show that blue light can increase melanin production, which can lead to brown spots and hyperpigmentation, especially in darker skin types. The complexion becomes less even and persistent marks may appear.
3. Weakening of the skin barrier
Blue light can affect the skin's ability to regenerate and maintain hydration. A weakened skin barrier is more vulnerable to external aggressors, which can lead to increased dryness, redness and sensitivity.
How can you protect yourself from blue light on a daily basis?
Fortunately, there are simple and effective ways of protecting your skin from the harmful effects of blue light:
- Choose skincare products containing protective filters: Some skincare products now incorporate specific filters to protect against blue light. These filters block or absorb blue light before it can penetrate the skin.
- Opt for anti-oxidant ingredients: Antioxidants such as Vitamin C, Vitamin E, and plant extracts (such as Cocoa peptides) help neutralise the free radicals generated by exposure to blue light.
- Limit screen time: Reducing the amount of time spent in front of screens and taking regular breaks helps to minimise exposure.

Protect your skin in a connected world
The effects of blue light on the skin can no longer be ignored. Although it is essential for our internal clock, excessive exposure, especially via screens, can lead to visible skin damage. An appropriate skincare routine, including protection against blue light, is crucial to maintaining healthy, luminous skin.
Opting for products formulated to counteract these effects, while incorporating good daily care practices, will help to limit damage and preserve the skin's youthful appearance in the face of these new aggressions.
