Birch sap is the core ingredient of the product. Therefore, the shape of the birch tree becomes the inspiration for the packaging design. We use typography to outline the shape of the tree trunk and add a small bump on the bottle cap to indicate the process of birch sap extraction. This unique and graceful gesture of the bottle brings the audience not only the imagery of the birch tree itself, but also a brand-new angle to interpret the highlights of the product. In order to reflect the smoothness of the cured skin, the surface of the bottle uses a comfortable and skin-friendly material. The overall minimalist design brings an elegant and graceful posture to the product, and defines a novel design language for Yoseido.
