Abstract

Artificial radiation is all around us. This refers not only to high energy visible light emitted by all kinds of screens but also WiFi radiation of smart devices. As we cannot escape from it and the consequences for our skin are still poorly investigated, protective measures can be taken in advance. Here we describe the use of an alga extract enriched in carotenoids capable of keeping the radiation threats away from our skin. The extract reduces WiFi and blue light-induced ROS generation and prevents overly carotenoid loss of the skin barrier leading to significant reduction in ageing parameters.
