Possessing viscous and elastic rheological properties, skin is viscoelastic. Mechanical creep, defined as the elongation of skin with a constant load over time beyond intrinsic extensibility, has been described as the vehicle harnessed for wound closure with presuturing, intraoperative tissue expansion, skin-stretching devices, and skin retraction with undermining. Resulting from the generation of new tissue due to a chronic stretching force, biological creep plays a role in conventional tissue expansion.
皮肤具有粘性和弹性流变学特性，是粘弹性的。机械蠕变被定义为皮肤在恒定负荷下随时间延长超过其固有伸展性的伸长，已被描述为用于伤口闭合的手段，包括预缝合、术中组织扩张、皮肤拉伸装置以及通过潜行分离进行皮肤回缩。由于慢性拉伸力产生新组织，生物蠕变在传统组织扩张中起作用。
