Face retouching

Hi, hope you are doing well.

For one of my clients, I have to create beauty AR filters using unity. I'm aware on how to create the makeup and color grading part, but I can't find a way to create a face retouching (that smoothes the skin, similar to Lens Studio or Meta Spark AR studio retouching).

Does anyone have tips for this? <3

FYI: neither ARCore nor ARKit have any functionality like this built in, so AR Foundation has no tools to help you. Your use case requires either a bespoke implementation or a third-party plugin that meets your needs.
