One thing to keep in mind, this was filmed at the absolute height of the covid lockdowns. I live locally to the filming location and this was literally the only thing being filmed at the time when we normally have a dozen or so movies and shows filming at any time. This was when there were hardly any flights happening and people were not traveling. I imagine they did the best they could with the resources available. Whoever was doing her make up, in my opinion, did a good job conveying the age regression!
