The embodiment of the invention provides an optical security element and an optical security product, and belongs to the field of security. The optical security element comprises a substrate, a micro-relief structure and an optically variable coating, wherein the micro-relief structure covers at least part of a area of at least one surface of the substrate; the optically variable coating is overlapped with the micro-relief structure; incident light irradiated to the at least part of the area is dispersed by the micro-relief structure into a preset area, wherein the preset area is an area in apreset three-dimensional angle taking specular reflection light irradiated to the at least part of the area by the incident light as a center; and the micro-relief structure includes hidden information, and a preset image is reproduced when the hidden information is decoded. The optical security product adopts the optical security element. Therefore, the mirror reflection is weakened or eliminated, a soft optically variable visual effect is presented, and the optical security element has two-line security hidden information.
