The term "piel" is the Spanish word for "skin." It refers to the outer covering of the body that protects internal organs, regulates temperature, and provides sensory information. Skin is made up of multiple layers, including the epidermis, dermis, and subcutaneous tissue, each serving specific functions. In addition to its biological role, "piel" can also refer to the texture or appearance of various materials, such as leather. In fashion and design, piel is often associated with quality and durability, making it a popular choice for clothing, accessories, and furniture.
