Résumé : |
Unlike UV, to date her has been little clinical research int the immediate and chronic effects of blue light on skin. Therefore we aimed to specifically investigate skin hyperpigmentation in human subjects caused by blue light. Our initial study, the first of its kind, assessed hyperpigmentation induced by single, high-dose or repetitive, moderate doses of LED blue-light exposure in vivo. In a placebo-controlled trial the study substantiated the protective effects of an SPF 30 sunscreen formulation containing performance in the blue light range.Evidence from the literature further indicates an association between the exposure of skin to blue light and the formation of reactive oxygen species (ROS). Previously, we demonstrated - through in vitro and ex vivo experiments - that a formulation containing a microalgae extract of Scenedesmus rubescens could enhance skin resilience to blue light-induced ROS formation. Here we report on the first clinical study with this microalgae product, which also confirms the protective effect against blue light irradiation in vivo. As a consequence we have developed a multi-mechanistic strategy for the prevention of hyperpigmentation caused by exposure to blue light. |
