Today, almost everyone spends hours on their smartphones. It is not surprising to find kids glued to cartoon videos and adults doomscrolling social media. However, research has found that the blue light emitted by electronic devices accelerate the process of ageing. Blue light emitted by mobile phones significantly affects the skin, particularly in the middle of the face. This exposure can lead to dry skin, even for those with naturally oily skin. Blue light damages the four layers of the epidermis, causing a loss of collagen and elasticity. This results in dull and dry skin. Many people with a history of long hours of exposure to phone screens find a noticeable change in their skin type, switching from oily to dry as a consequence of prolonged blue light exposure.Blue light exposure also disrupts the body's circadian rhythm, which is linked to sleep and hormonal functions. When blue light from mobile devices interferes with this rhythm, it reduces the release of melatonin, the hormone responsible for inducing sleep. This lack of sleep and melatonin together boosts an increase in oxidative stress in the body, resulting in dry, swollen skin. Over time, this can accelerate the aging process, making it even more important to manage blue light exposure, particularly in the evenings.What Is The Solution? For those looking for a counter to their exposure to blue light, sunscreen is important. Health experts recommend applying sunscreen every three hours, regardless of the season. He stresses that sunscreen is just as vital as eating or drinking water. Even when staying indoors, sunscreen is necessary as it protects against blue light, LED light, and even heat from appliances like gas stoves. Are Anti-Ageing products Useful? For those using anti-aging products, it's essential to pair them with sunscreen. While anti-aging products hydrate the skin and stimulate collagen production, they can't protect the skin from environmental damage. Sunscreen serves as a protective shield that enhances the effectiveness of these products. What Are The Early Signs Of Ageing? Fine lines and wrinkles, especially under the eyes, are among the first visible signs of aging. While these are inevitable with age, experts emphasize that people are seeing the onset of aging as early as 25, with prolonged mobile phone use contributing to fine lines around the eyes. Additionally, sagging skin and laugh lines can appear prematurely. To prevent these signs of aging, it is crucial to keep the skin hydrated and limit screen time. Anti-aging routines should ideally begin at 25, with guidance from a dermatologist. While blue light is not as harmful as UV rays, long-term exposure can still damage the skin. UVA rays cause internal skin damage leading to wrinkles, while UVB rays impact the outer layer, increasing the risk of skin cancer. While blue light may not be as dangerous, studies suggest it can darken the skin tone over time. To mitigate its effects, regular use of blue light is advised. There are blue light filters also available.
