A Melanin Derivative to Shield the Skin from High Energy Visible Light

High energy visible (HEV) light recently has been suspected of causing as much damage as UVA and UVB combined. Thus, the present paper describes a fractionated melanin tailored to absorb light in the visibile 400―500 nm range. In addition, because the material exhibits color, the authors focus on formulation techniques to incorporate it into semisolid formulations.
