This kind of software usually provides beauty filters, skin optimization and other functions when users make video calls through real-time face tracking technology, so that users can show their beautified appearance when chatting on WeChat video.

Wechat's native video calling function does not have a beauty option directly built in, so we need to use third-party tools or applications to realize the beauty effect in WeChat video calling. If you want to use the beauty function in WeChat video, users need to download and install plug-ins or applications that support WeChat video beauty, and set and enable this function according to the instructions provided by the application.
