When you get a bespoke facial from Jennifer Brodeur at Bella Clinique in Montreal, you’ll also meet “Max,” the LED-light-therapy machine that Brodeur designed in 2003 and always refers to as a person. (It’s actually called “Max+.”)

The machine, she explains, harnesses research from NASA and uses light wavelengths to treat skin concerns. Skin cells absorb the UV-free light as energy. Red-light wavelengths, for example, are said to stimulate fibroblasts to create collagen, while yellow light tightens skin.

“It’s interesting because you don’t feel anything, so a lot of clients at first were like, ‘Are you sure you’re doing something?’” she says, laughing. Any disbelievers can call Oprah; Brodeur has been treating her since 2012.
