“I’ll take over from here,” said Courteney Cox, appearing in a lab coat as she surprised a room of faculty students.

She was inside Dermalogica’s headquarters near Los Angeles. The audience — aspiring skin professionals attending the wonder brand’s monthly Future Industry Professionals Day — had been watching a fellow apprentice get her face washed as a part of a skin treatment. Cox was tasked with taking on the job.

“Luckily, it went rather well,” the actress said afterward. “The people didn’t mind and didn’t boo me. They clapped, and it went well. And the girl, she appeared to like my technique.”

Cox used the Dermalogica Each day Microfoliant, a product she exfoliates with day by day herself.

“Let’s put it this manner, her face is extra clean,” she added.

Cox is partnering with Dermalogica — the skincare brand founded in 1986. Launched by Jane and Raymond Wurwand, it’s owned by Unilever.

“I get sent a number of products, and I don’t prefer to attach my name to anything unless I feel in it,” she said of the collaboration.

She’s also a fan of the Dynamic Skin Recovery SPF 50 and Dynamic Skin Retinol Serum. “They’re tried and true,” she said.

Cox has history with Dermalogica — products will be seen in the lavatory of Monica Geller, her character on “Friends.”

“I’ve been knowing about Dermalogica without end,” she said.

“We’ve realized from postings and from other things that she’s an actual fan,” said Aurelian Lis, chief executive officer of Dermalogica.

And Cox, he added, brings fun to skincare along with her comedic ways: “Courtney has a humor to her that makes that partnership possible…Those two things together, she appeared like a extremely good partner for this. We actually need to spotlight expertise. Working with Courtney to spotlight the expertise is, for us, an interesting way.”

Cox has garnered fans online along with her humor, with 13 million followers on Instagram and 1.3 million followers on TikTok.

“I like showing the silly side of myself,” she said of her videos. “I would like to, in my very own way, show my passion for the products.”
