Most of us know the sun can damage the skin if you miss the sunscreen be it during summers or winters, but now experts say another silent factor may be adding to the problem and that is the blue light emitted from phones, laptops and tablets. As screen time continues to rise, doctors say they are seeing a clear link between heavy device use and early signs of skin ageing.
Speaking about its impact, Dr. Shraddha Deshpande, Consultant Plastic Reconstructive and Aesthetic Surgeon, Wockhardt Hospitals, Mumbai Central, explains, “People assume only sunlight causes ageing, but blue light can also contribute to damage. It penetrates deep into the skin and can speed up the appearance of fine lines, dullness and pigmentation.”
Blue light is a type of high-energy visible light that digital screens emit. While it is not as harsh as ultraviolet rays from the sun and won’t cause sunburn, it affects the skin in slower, deeper ways. Over time, long hours of exposure can trigger the production of free radicals, which break down collagen and elastin. These proteins are responsible for keeping skin firm, smooth and youthful.
Why the effects are stronger on Indian skin
Dermatologists point out that the effect is stronger in people with melanin-rich skin. Blue light has been shown to increase pigmentation, leading to darker patches and uneven skin tone. This matches what many skin specialists in Indian cities are witnessing, which is a noticeable rise in patients seeking treatment for stubborn pigmentation and early wrinkles, especially among those who spend long hours on screens.
Another challenge is that screen exposure gives no warning signs. There is no heat or burning sensation, so most people don’t realise the harm. Dr. Deshpande adds, “The tricky part is that blue light damage builds up quietly. One may not feel anything, but the stress it causes to the skin becomes visible over months or years.”
Late-night screen time makes it worse
Using devices late at night also affects sleep. Blue light suppresses melatonin, the hormone that regulates sleep. Poor sleep is known to speed up ageing, making the skin look tired, dull and less elastic.
How to protect your skin
The good news is that protecting the skin doesn’t require cutting down technology entirely. Using a broad-spectrum sunscreen daily, even indoors, can help. Many modern sunscreens are formulated to defend against blue light too.
Dermatologists also recommend skincare products with antioxidants like vitamin C, niacinamide and ferulic acid, which help reduce the free-radical damage caused by screens. Turning on blue light filters or night mode on devices and taking regular screen breaks are simple but effective steps.
A new ageing trigger in a digital lifestyle
As our digital lives grow more demanding, experts say it’s important to rethink how we protect our skin. The sun remains a major source of ageing, but in today’s world, the constant glow of screens may also be quietly contributing to the problem.
