According to Naturex, DNA damage in human keratinocytes was reduced by up to 75% when incubated with Eliorelys.
“The results indicate that Eliorelys exerted a protective effect against blue light-induced DNA lesions,” the company says.
Eliorelys is extracted from cherry tree flowers using a patented process based on Natural Deep Eutectic Solvent (NaDES) technology, the company explains.
“In topical skin care applications, it offers a superior phytochemical profile that delivers protection against both UV and blue ray-induced cell damage.”
Blue light: the next frontier for light protection
Blue light from screens has been regularly tipped to be an area of focus for innovation in skin care over the past few years, but has been beset somewhat by lacking studies to indicate genuine efficacy.
Companies working in the space of blue light protection ingredients need to invest in assays to prove their products work for consumers to become properly enthusiastic for the trend.
New testing methods
Naturex’s recent study suggests it is one company doing just that.
“Until recently, artificial blue light was not thought to have the same harmful effects [as UV radiation],” explains Naturex.
“But recently published studies, confirmed by Naturex’s own internal testing, have concluded that blue light can in fact lead to damage in cultured human keratinocytes and live skin, causing levels of skin ageing similar to that triggered by UVA radiation.”
On average, says the ingredients player, people spend five hours a day in front of a screen, and 90% of 20-65 years olds use electronic devices every day.
If companies are able to convince consumers, these figures suggests there is a large, untapped potential consumer group to court.
