Not only that but the machine learning models on those ARs are so successful that judging from our context (of non-Chinese apps we're normally exposed to), I'd be semi-surprised that we can algorithmically apply makeup so correctly with ambient lighting on a single still frame on a compute server, much less locally, in real-time on a low powered phone.
