Because we’re all about the prep.

Behind-the-scenes Oscars details are now just as important as the red carpet itself, with everyone’s eyes fixed on what celebrities do to ensure they turn up to the Academy Awards looking their best.

Leading up to this year’s awards evening, popular self-care treatments have included spiritual readings with mystic Sylvain Sellam, facial treatments from Cynthia Franco and sound-bath sessions with Kundalini teacher Guru Jagat.

With social media playing a crucial role in documenting this prep, stars like Kelly Marie Tran of Star Wars fame and Emma Roberts took to Instagram to share their routines with us before the big event.

Scroll below to see how some of Hollywood’s biggest stars got ready for the 90th Academy Awards:

Kelly Marie Tran:

HAPPY OSCARS DAY!! That’s what most people are celebrating today, but I also consider this day GLAM SQUAD APPRECIATION DAY! I think every actor can agree that we are nothing without our glam teams! SO THANK YOU TO @waymanandmicah (their amazing assistant, Patrick), @storyofmailife (her assistant Mia, who I am excited to meet!) , and @marktownsend1 (and his amazing assistant, @alexhenrichs). Also, I forgot to photograph the amazing @deborahlippmann (and her wonderful assistant) yesterday — they did my nails! 💅🏻 YOU GUYS. For real, anyone can look red-carpet ready if they have a team of 8+ people getting them ready! It takes A TON of behind the scenes work, and although I’m enjoying every moment, I’m cognizant of perpetuating an unattainable ideal… That’s why I think it’s important to be transparent about this process! I’m a lucky girl, and I have THE BEST glam team, but y’all know I DO NOT LOOK LIKE A RED CARPET GIRL EVERY DAY. Don’t let my “sometimes” fool you into thinking it’s my “always”. Just sayin’ 💁🏻💁🏻💁🏻 SEE YOU SOONSIES!!! ❤❤
