真皮是指天然皮革，由动物皮加工而成。假皮革是指合成革或其它貌似真皮，实际是由化工原料人工合成的产品。自合成革出现以来，就一直模拟仿
天然皮革，经过多年的努力，在各种特性上已与天然皮革非常接近，尤其是在外观上几乎使人难以分辨。但天然皮革的结构非常复杂，要想人工天衣无缝地模仿出来，目前条件下还是很困难的，甚至是不可能的。虽然假皮革有时也会“以假乱真”，但掌握了鉴别方法，就可将真假皮革分辨出来：
1、看：首先应从皮革的花纹、毛孔等方面来辨别，在天然皮革的表面可以看到花纹、毛孔确实存在，并且分布得不均匀，反面有动物纤维，侧面层次明显可辨，下层有动物纤维，用手指甲刮试会出现皮革纤维竖起，有起绒的感觉，少量纤维也可掉落下来，而合成革反面能看到织物，侧面无动物纤维，一般表皮无毛孔
对这类产品的辨别方法是：（1）先看外表，质地均匀、无伤残、无粗纹，无任何缺陷的可能是人造皮革；而真皮革的质地都有一些差异，特别是革制品的主要部位和次要部位的结合处差异应明显些；（2）再仔细观察毛孔分布及其形状：天然皮革孔多且深不宜见底，略为倾斜；而毛孔浅显垂直的可能是合成革修饰面革。（3）从横切面上看，天然革的横断面纤维有其自身特点，各层纤维粗细有变化。
而合成革的纤维各层基本均一，表面一层呈塑料膜状。
2、摸：真皮用手触摸，滑爽、柔软、丰满、有弹性，将皮革正面向下弯折90度左右会出现自然皱褶，分别弯折不同部位，产生的折纹粗细、多少，
有明显的不均匀，基本可以认定这是真皮，因为真皮革具有天然性的不均匀的纤维组织构成，因此形成的折皱纹路表现也有明显的不均匀。而一般人
造合成革面发涩、死板、柔软性差，手感像塑料，回复性较差，弯折下去折纹粗细多少都相似。
3、嗅：天然皮革具有一股很浓的皮毛味，即使经过处理，味道也较明显，而人造革产品，则有股塑料的味道，无皮毛的味道。
