I really love Jaylah's design, it's so gloriously crisp! And those eyes! It's not something that was as easy to create as you might think at first glance, as /Film noted in their set report article:
The make-up for Sofia Boutella‘s alien character Jaylah is a mix of prosthetics and traditional makeup techniques and a wig. Harlow says its of the hardest make-up applications on the show because it’s “so clean.” The entire forehead is an appliance and everyplace you see black is a silicone prosthetic. Every day Sofia works she has to undergo three and a half hours of application and a half hour of removal at the end of the day.I wonder if this is the start of a second round of character posters, or whether Jaylah is just being singled out for being so eye-catching.
