Can Blue Light Harm Our Skin?

Recent studies have shown that blue light can cause the generation of reactive oxygen species. According to the National Cancer Institute, it is an unstable molecule that contains oxygen and reacts with other molecules.

According to CNET, these reactive oxygen species can damage skin cells and result in faster aging due to the breakdown of collagen and elastin.

Other studies have also suggested that blue light may cause ongoing pigment changes.

According to Dr. Michele Farber of the Schweiger Dermatology Group in New York City, studies on blue light and skin damage have recently emerged but there is no reason to ignore the potential for skin damage.

Meanwhile, Dr. Marie Bright, a New York City -based medical and cosmetic dermatologist, told CNET that blue light can damage the skin in many ways.

One of the many damage that blue light can cause is that it “causes oxidative stress, which can cause inflammation and damage to collagen.”

Blue light can also interfere with the activity of melanocytes. This can lead to uneven and excessive pigmentation. In addition, it can contribute to photoaging, or aging of the skin caused by light waves.

Another effect that blue light can have on our skin is that it can weaken the outermost layer of our skin and delay its recovery from daily skin stresses.
