Forest mood "is a tree ring for the design inspiration of biological plastic skin care products packaging. As consumers around the world pay more attention to organic and environmental protection, not only food, but also to the chemical components in skin care products. Although the market for skin care products containing organic ingredients is expanding, there is not enough attention to the plastics used in their packaging. Recently, due to environmental regulations, single-use plastic products have been restricted, and consumers have a more direct understanding of the impact of plastic packaging on the earth's environment. Therefore, the packaging made of this special material that can be decomposed naturally not only conveys the message of using environmentally friendly skin care products, but also makes users more actively aware of their participation in nature, me and environmental protection through visual design.
