I do very much hope that you told the candidate what spooked you. Ideally, you would have done this early in the interview, giving them a chance to disable any video filtering / face-beautifying software that they may have been running.

If you didn't do either one of those, perhaps you now know enough so that next time you will be able to give the interviewee a chance to demonstrate whether or not they're using a "Smooth over my facial blemishes because I'm uncomfortable with how my face looks and want it to look 'prettier'." filter.

Best of luck with your interviews!
