Karina García, a Venezuelan woman living in Barcelona, tells us about her startup, Mandarina Care, whose mission is to limit consumption of microplastics, chemicals, and toxic and carcinogenic substances with her lines of organic solid cosmetics.

Medical student Patricia Martí tells us about the study she is conducting in the village of Adícora. The study is a look at the incidence of skin problems caused by sun exposure in this town where many people work outdoors, including quite a few fishermen.

Patricia will soon be a full-fledged doctor of medicine, but first she must complete the internship she is doing in the rural Venezuelan community of Charaima, on the Peninsula de Paraguaná. She tells us a little bit about the road she’s travelled to get to this point in her academic career.
