Blue Light Science 101: Harmful or Helpful for the skin?
Blue light has become a beauty buzzword. Is it a pollutant that causes digital aging, or is it an efficacious skin treatment? The market for blue light skincare is on the rise, and cosmetic products advertise both blue light protection and blue light therapy. We’ll explore popular blue light technologies and elucidate the science behind them. This is a technical 101 talk on the basics of blue light and how it interacts with the skin, concluding with tips for product formulation, claims, and testing.
