A concept design project for a fictional vacation sunscreen was assigned by the Korean design magazine 'Monthly Design'. Emphasis was placed on the environmental impact of sunscreen on marine life. An eco-friendly brand was proposed, advocating for environmental consideration during vacations. A modular sunscreen concept, with single-use solid portions the size of a thumbnail, was introduced. These are melted by hand for application. Five iconic shapes inspired by coral reefs were designed to give a sense of environmental protection. Lightweight, travel-friendly packaging made from cork material was used.
