With new research indicating potential dangers to skin health caused by regular exposure to high-energy blue light, it is more important than ever to customize your skincare regimen and be proactive about the health of your body's largest organ. 

The Dark Truth About Blue Light

In our modern world dominated by digital technology and smartphones, it feels impossible to avoid the blue glow of a screen, whether you work from your computer, are hooked on TikTok, or fall asleep binging Netflix more often than you'd like to admit. The digital screens and fluorescent/LED bulbs that light up our lives emit a distinct blue irradiation, in the 400-500 nm range of the electromagnetic spectrum. Depending on the intensity and duration of exposure to this wavelength of blue light, it can have either negative or positive consequences. 

This dual nature is understandably confusing for some people. Photodynamic therapies for actinic keratosis, skin cancer, acne and other conditions utilize short-duration exposure of blue light as a beneficial treatment, but extended exposure to high-energy blue light can lead to cell shrinkage, discoloration, swelling, sagging skin, or inflammation in those same areas. 

A recent study published in the Journal of Dermatological Science concluded that blue light (BL) irradiation can lead to “photoaging,” or accelerate the aging process of the skin, meaning that certain key functions of skin cells are inhibited. Specifically, BL irradiation down-regulates a critical gene responsible for producing collagen, the most abundant protein in the body and a key component of connective tissue in the skin. Secondly, excessive blue light exposure prevented the spread of fibroblasts—another cell type that contributes to connective tissue. These two factors can lead to a host of issues within skin cells, from the formation of wrinkles and signs of aging to discoloration and compromised immune function. 

Hyaluronic Acid Treatment for Blue Light Damage

Given that screen use is unlikely to decrease in the near future, the risk of blue light damage is something that affects a significant portion of the global population. Treating any apparent symptoms and proactively nourishing the skin cells, particularly on your face, is an essential step for skin-conscious screen users. 

To combat the potential decline in fibroblasts and collagen in the epidermis of your exposed skin, products with hyaluronic acid are an excellent choice. This powerful compound is naturally produced in the body, but it declines as we age, and some research has found that hyaluronic acid can help to boost collagen levels. Additionally, hyaluronic acid is an impressive emollient, binding to water and helping your cells retain moisture. This can add a supple and smooth texture to your skin, while also reducing inflammation, two of the common symptoms of excess blue light exposure.

If you want to prevent skin barrier damage while protecting your skin cells from the damage and premature aging associated with blue light irradiation, choose skincare products with hyaluronic acid as a leading ingredient.
