One of the many amazing parts of This Is Us is that the show's time changes allow viewers to see their favorite characters through different decades—that is, ages. Rebecca, played by Mandy Moore, is no exception to that rule, but she let fans in as to how she makes her dramatic age change.
All over Instagram Live video, naturally:
Mandy lets viewers into the behind-the-scenes makeup that goes into making the 33-year-old actress look 66 years old. According to People, the full video also shows the actress commenting, "This is 66. Look how incredible all of this is. We haven't even done any of the painting and stuff yet."
Later on, she exclaims: "The hardest part is the removal process. It's pretty tricky and it's really hard on my skin. I have really sensitive skin."
It's all as she helpfully captioned her Live videos: "You know what's happening / Getting older is a lot of work."
Moore's performance is just one of the many reasons viewers have flocked to This Is Us, which is up for 11 Emmy nominations.
