Kendall Jenner has joined forces with Therabody as a new ambassador

This week, the brand has launched its new hands-free TheraFace Mask Glo, which uses red, infrared and blue light, and vibration.

The mask can provide 10 treatments before its battery needs recharging.

Kendall wrote on Instagram: "As a true fan of the brand, I'm so happy to be a part of the @therabody family."

She will appear in various pieces of content endorsing the product, including a campaign across TV, social media and retail, as well as a "hero video" speaking about the benefits of the mask.

John Slomon, Therabody's chief marketing office, told WWD: "Kendall has always been extremely wellness-minded.

"She even has a wellness room in her home, and the whole family has been a huge fan of Therabody from the very early days. Kim Kardashian even teased our original, first-edition mask on her social channels.

"In the world of AI, customers want real people, and they want to hear their perspectives and their use cases."

Therabody's first face mask launched in 2023, and the company has now sought to develop a new device maintaining high performance at a lower cost for customers.

The original cost $650, while the TheraFace Mask Glo will set you back $380.

Tim Roberts, the company's VP of science and innovation, said: "We had tremendous success with our first LED mask.

"It's a core fundamental belief of Therabody that we want to democratise and bring to as many people as possible [our] clinically effective and safe technologies."

The more lightweight device is still cordless, meaning users can multitask, while there is also a vibration scalp massage feature.

He explained that the team reduced the same of lights from 648 to 504 to make it more accessible

He added: "We went from three minutes per therapy and nine minutes total to four minutes per therapy, 12 minutes total, to make sure that dose evened out."
