MOST of us would attribute wrinkles, fine lines and dark spots from skin ageing to prolonged or excessive exposure to the sun – or just a natural process as we grow older.
But an insidious culprit has emerged in today's digital age – the infamous "blue light" from our screens.
Could binge-watching your favourite show or doom-scrolling through social media sabotage your youthful glow and make you look years older?
VERDICT:
TRUE
Studies suggest that prolonged exposure to this so-called "blue light" has damaging effects on the skin.
While blue light is commonly associated with sleep disruption, its impact on the skin is becoming a concern.
A study published in the Journal of Cosmetic Dermatology showed that blue light can penetrate the skin and cause oxidative stress.
This exposure generates free radicals, which break down collagen – a protein that helps maintain skin elasticity.
As a result, the skin may suffer premature ageing, developing fine lines and wrinkles.
Research also suggests that blue light may hinder the skin's ability to repair itself, leading to a reduction in collagen production.
Although blue light is less damaging than ultraviolet (UV) light, it still has a cumulative effect, particularly for those who spend long hours in front of screens.
Another study found that blue light could accelerate skin ageing, especially with prolonged exposure.
People with fair skin or those frequently exposed to artificial light may be more susceptible to its harmful effects.
To protect against blue light damage, dermatologists recommend using blue light-blocking skincare products, applying sunscreen regularly and taking breaks from screen time.
