Margot Robbie's spray tanner said she had to use less product on the 'Barbie' star because she went so blonde for the role

• Liz Pino has been spray-tanning stars for years, including Margot Robbie.
• Pino said she's never worked with a star who "cares more about her friends, family, and people."

Liz Pino has been spray-tanning celebrities for more than a decade, but it's Margot Robbie who has made one of the best impressions.

And when she worked with the star on "Barbie," the spray tanner told Insider she had to go easy on the product since Robbie went "much blonder" for the part.

Pino said she has worked with Robbie on multiple films, and recently got her glowing for the "Barbie" world premiere. And the esthetician — who works at Queen Bee Salon & Spa in Culver City, California — said that the Australian actress is just as lovely as she seems.

"If you are a person that thinks Margot Robbie looks like the nicest person, her smile lights up the room, she's absolutely the most down to earth person — then you're 100% correct," Pino said.

Pino added that she's never worked with a celebrity who "cares more about her friends, family, and people," than Robbie.

"It's amazing, the camaraderie she has with her own people," Pino said. "It's actually very refreshing and beautiful, to be honest. Maybe that's why she's so pretty."

"What's in the inside," she added, shows on "the outside."

Before Pino started working with the future "Barbie" star, she said she had to prove her skills to Pati Dubroff, Robbie's makeup artist.

"Our job as spray tanners isn't just laying down some color and calling it a day, that is the absolute antithesis of what we do," Pino said. "We have to match tone, we have to match color, we have to sometimes hit a certain era. There's a lot more color match in our art than people realize."

Pino said she helped consult the UK makeup artists who worked on Robbie's shade for "Barbie" during filming in London. And when it came time for the world premiere, she created a custom-blended tan to match Robbie's "Barbie" look.

"Margot is one of those people that a little bit goes a long way," Pino said. "We also have to match hair very specifically as well. She's much blonder for this, so even less is more."

After 20 years of experience, Pino has become a master of spray tanning and it's many tips and tricks — including a $5 hack for getting rid of orange hands.

"Your hands are going to touch your body one way or the other, and the first thing that spray tan loves to transfer onto is your hands," she said. "Nothing looks worse than a pair of messed up hands, in my opinion."
