Kemin (Des Moines, Iowa) has conducted in vitro studies to confirm the blue-light-absorbing capacity of its plant-based FloraGLO Lutein Topical at different concentration and concluded that the ingredient effectively shields the skin against high-energy visible (HEV) light.

HEV (also known as blue light) comprises natural light and man-made light to which humans are regularly exposed, particularly from electronic screens.

According to Kemin, the study measured "the cell viability as the percentage proliferation of metabolically active human epidermal keratinocyte (HEK) and human dermal fibroblast (HDF) cells exposed to blue light for 9 hours, and the intracellular Reactive Oxygen Species (ROS) released in cells, in response to blue light exposure"

"[P]rotecting the skin against harmful blue light rays could be an indispensable way to reduce the inevitable skin damage from visible light and an introduction to a new need in the beauty regimen to protect skin from full solar spectrum damages”, said Satish Nayak, Ph.D., research and development director for the personal care division at Kemin Industries.
