When it comes to photoaging, most are already overtaken by the harmful effects of UVA and UVB rays. The beauty market is saturated with sunscreens and restorative beauty products to prevent and recover from sun damage, respectively. But when it comes to market trends, another equally harmful sinner leads to photo-damage of the skin, and that’s blue light.
“Blue light, also known as high-energy visible (HEV) light, is radiation emitted in the visible spectrum. It has a wavelength of 450-495 nm, which can penetrate the layers of the skin, causing oxidative stress by releasing free radicals,” reveals Doctor Gulhima Arora, Senior Consultant Dermatologist and Director, Mehektagul Dermaclinic, New Delhi. She further explains that these free radicals are responsible for accelerated damage to elastin and collagen fibers in the skin by stimulating enzymes that increase their degradation, damage DNA and disrupt the skin barrier. Also, excessive blue light damage can lead to premature aging, cell death, increased pigmentation, spots, uneven skin tone and dullness. “Exposure less than 60 minutes can damage the skin,” she says.
How harmful can blue light really be?
Like most skincare trends, the jury is still out on the need for blue light protection in beauty products. But what many don’t realize is that there are many sources of blue light that you are exposed to every day. Even though sunlight is the main source of blue light emission, some scientists believe that it is only a small part of it. Device screens are considered to be one of the biggest contributors to blue light emission and given their widespread use, they can be quite harmful. Artificial lights, especially fluorescent and LED lights, are another source.
Another warning sign is the loss of the ozone layer resulting in excess radiation hitting the earth’s surface. This led to an increased exposure in terms of quantities to HEV. “Not just in theory, but also in practice, we see patients with exaggerated pigmentation issues, premature wrinkles, uneven skin tone and post-acne redness,” Dr. Gulhima reveals. Due to its ability to penetrate the deepest layers of the skin where collagen and elastin reside, blue light’s uncanny ability to penetrate deeply is why it is being touted as a concern today. serious.
The popularity of skincare with blue light protection
Increased awareness of blue light damage and the actual damage seen by experts working closely with the skin has led cosmetic scientists on the warpath to research the technology. Market trends are also proof of this. “Unfortunately, conventional sunscreens are ineffective in combating blue light, so the demand for protection against blue light has increased thanks to better awareness and information about its future harmful effects,” reveals Dr. Merin Liza Jacob, co – founder of Green and Beige skin care. The recent pandemic, which has made existence in the virtual world a new normal, is also driving overexposure to screens for work and pleasure. In addition to this, energy saving LED lighting is becoming extremely common in workplaces and homes these days.
How exactly does blue light protection work?
Products formulated with blue light protection contain active ingredients that can block or absorb HEV (390-500 nm) and protect photoreceptors in the skin. They also have a high antioxidant capacity to reduce the production of free radicals, which are believed to speed up the aging process. “Capsicum Annuum fruit extract, a powerful antioxidant with HEV (390nm to 500nm) absorption capacity, is used in the Green And Beige skincare collection to protect the skin from the harmful effects of light. blue,” reveals Dr. Merin.
Dr. Gulhima recommended paying attention to a few additional ingredients when choosing. “Iron oxide is the strongest filter besides titanium dioxide and zinc oxide. These are the most common ingredients in tinted sunscreens. She additionally recommends antioxidants like vitamins C and E and ferulic acid to help protect the skin from oxidative damage caused by blue light.” Plants such as marigold, carrots, cocoa nibs, ginger, and lycopene are gaining popularity as armor for the blue light protection,” she says. Certain vitamins like niacinamide can also help protect against blue light.
In conclusion, blue light shielding beauty products can offer management of issues like reducing wrinkles, fighting hyperpigmentation, decelerating skin aging, and even helping with under eye care. But what about blue light protection in makeup? Dr. Gulhima also has insight into this. “I think it’s a good idea to incorporate it into makeup. Main filters can easily be incorporated as they are tinted into pigment bases like foundations, concealers, BB and CC creams. Makeup is often the last layer of application over skincare products, and reapplying skincare on top is often not practical, so incorporating these ingredients is like a final shield,” a- she declared while signing!
