BPI Melanin™
A tint that mimics the natural sunlight protection pigment
of the skin. This is a yellowish-brown color that has been
chosen not just for its appearance, but for the shape of the
spectral curve which resembles that of natural melanin. The
destructive, high-energy side of the spectrum is reduced in
proportion to its energy content, but enough blue light is
transmitted to allow natural perception of color.
