In Vitro Blue Light
Considering that long-term exposure to BL (from the sun light, digital and electronics devices using LED technology, etc.), this damage induces similar physiological responses in the skin to UV exposure which translate to the typical signs of premature skin aging such as loss of elasticity, dryness and fine lines. This innovative in vitro method consists in evaluating the Blue Light protection levels expressed by the BL-CW (UV/VIS balance) and the % BL (percentage of intensity of BL protection) from a sunscreen product through the spectrum (from 290 nm to 500 nm) measured by means of a spectrophotometric method. To take into account any potential photo-unstability, the product was pre-irradiated before measurement. Finally, this method relies on the use of in vivo SPF results for scaling the absorbance curve.
