Various studies have shown that blue light doesn't appear to be capable of causing sunburn or skin cancer as UV can. In some instances, blue light can even be beneficial to our skin – but only in controlled ways. Although it may not lead to more serious skin concerns, blue light still has degenerative effects; it does not penetrate as deep into the skin as ultraviolet light, but it can cause premature aging of the skin, and the long-term effects are unknown. Blue light has also been shown to promote free radical damage, which stimulates pigment production and can lead to dark spots.
A growing number of startups, small cosmetics brands, and large companies like Lubrizol and Naturex are investigating the short- and long-term effects of electronic blue light, as well as developing products to address them. Many of the companies in this space are using natural ingredients like flower and algae extracts for solutions. Givaudan launched its "Syncronight" product line that utilizes gardenia fruit extract as a prebiotic ingredient for its new products to combat the effects of blue light on the skin. The use of gardenia extract to address the health of the skin microbiome originated from traditional Chinese medicine methods. Givaudan has coupled natural ingredients with skin microbiome analysis to select the best-performing ingredients for its products. Givaudan uses i-MAPS both internally for product formulation development and for its customers.
