The 'Stranger Things' makeup team says they pamper the cast with $75 lip balm because they can't always wear makeup on set

• Insider spoke with "Stranger Things" makeup artists Amy L. Forsythe and Devin Morales.
• Sometimes, they said, the cast uses $75 lip balm when their characters can't wear makeup.

"Stranger Things" is a show filled with monsters and mayhem — not glamour.

So the Emmy-nominated makeup team that works behind the scenes found a way to make the young cast feel good on set when their characters aren't wearing makeup.

"You just pamper them a little bit more — do a lot of skin prep and make them feel yummy," lead makeup artist Amy L. Forsythe told Insider.

"I think most of them wear La Mer lip balm, even if they're not allowed to wear makeup," Devin Morales, a makeup artist who joined during season four, added.

La Mer is a luxury beauty brand known for its cult-favorite moisturizer, which can cost up to $$2,545 per bottle.

Its lip balm — which is said to be hydrating with "a hint of mint" — is equally pricey, retailing for $75 online.

"Oh my gosh, I apologize profusely for getting children addicted to La Mer lip balm," Forsythe joked. "All I could think after season two was all of these kids going out into the world on their other jobs and being like, 'Yeah, I use La Mer lip balm.'"

But it's not just the luxury of the lip balm that the "Stranger Things" cast loves. According to the makeup department, it's the feeling of being pampered that helps them relax.

When working with Millie Bobby Brown, the artists said, sometimes they use a dry mascara wand on her lashes to create the illusion of applying makeup.

"She just likes the feeling of getting to wear mascara, you know what I mean?" Forsythe said of Brown. "I get it."
