Is blue light protection necessary? Experts share their insights

Binging and hours of scrolling is every generation’s guilty pleasure today and we all are in dire need of some intervention. Excessive screen time is loosely translated as excessive exposure to high-energy visible light/blue light, hence resulting in damaged skin. Further offering their viewpoint on whether blue light is a bane or boon (in some cases) we have experts sharing their insights on blue light protection.

The post-pandemic era introduced us to the world of the ‘new normal’ and left behind increased screen times as a parting gift. Be it work from home or excessive scrolling hours on the gram, everything comes with its fair share of pros and cons, and in this case, our deteriorating skin is the biggest con! No matter how addictive or satisfying those reels might be or how urgent those deadlines are, the blue light or high-energy visible light released from those screens makes our skin prone to damage. Contrary to this belief, some also believe blue light has its set of pros to look into. While factors like premature ageing, and dullness, are a few of the many outcomes of exposing ourselves to blue light rays, it is also said blue light holds benefits for our well-being. So, digging deeper into the details of the same here we have experts weighing in all that we need to know about blue light protection.

All we need to know about blue light protection

Blue light, or high-energy visible (HEV) light, is part of the visible light spectrum and is known to penetrate the skin more deeply than some other types of light. Blue light is emitted by digital screens, smartphones, and other electronic devices. However, it is important to note that the biggest source of blue light is the sun and not screens. Blue light protection products are skincare and makeup formulations designed to shield the skin from the potentially harmful effects of blue light.

Blue light is thought to contribute to brown spots on the skin and hyperpigmentation such as melasma especially in skin of colour. There’s also evidence that as blue light penetrates the skin, reactive oxygen species are generated, which leads to DNA damage, thereby causing inflammation and the breakdown of healthy collagen and elastin, as well as hyperpigmentation.

Proving the efficacy of blue light protection products poses challenges, given factors such as diverse screen types, intensities, and individual skin responses. The influence of blue light on the skin might depend on the dosage, complicating efforts to replicate real-world conditions accurately in laboratory settings. Blue light holds benefits for our well-being by regulating the body’s circadian rhythm, enhancing mood, and supporting memory and cognitive function. Dermatologists also utilise blue light in acne treatment. Blue light protection products include sunscreens, moisturisers and even makeup.

Blue light protection products often contain antioxidants like vitamins C and E. These help neutralise free radicals generated by blue light exposure, preventing oxidative stress on the skin. Some formulations use Pigmentary titanium dioxide (larger particles of titanium dioxide) in foundations and tinted sunscreens to give them coverage. The larger particles scatter visible light so Less of it reaches your skin. Certain ingredients, such as iron oxides, absorb blue light, reducing the amount of blue light reaching the skin.

A scientific consensus regarding the need for dedicated blue light protection products is still developing. While blue light protection products can be part of a comprehensive skincare routine, other measures, such as reducing screen time and maintaining general skin health, are important. Individuals with significant daily exposure to digital screens may consider blue light protection. Those in front of screens for extended periods, especially in professional or educational settings, might benefit from incorporating these products.

Blue light protection products, often found in makeup and skincare formulations, aim to shield the skin from the potentially harmful effects of blue light emitted by digital screens and electronic devices. They are typically characterised by antioxidants, such as vitamins C and E, and sometimes specific ingredients like iron oxides, which act as a barrier against blue light exposure.

Benefits of using blue light protection: Potential prevention of oxidative stress and reduction in the likelihood of free radical damage

Drawbacks: Exposure to blue light can bring on premature ageing and hyperpigmentation, irritation to the eyes

The formulation and concentration of the product infused with blue protection play a vital role in understanding the efficacy of blue light protection in makeup and skincare products. It’s essential to complement the use of blue light protection products with other sun protection measures.

In conclusion, incorporating blue light protection products into a skincare routine can be beneficial, particularly for individuals exposed to electronic devices regularly. However, their effectiveness should be considered in conjunction with broader skin protection practices.
