Kate McKinnon Jokes She Likes to Spend ‘Zero Minutes’ Getting Glam: I Am a ‘Person of the Woods’ (Exclusive)

When it comes to getting ready, Kate McKinnon likes to take a no-frills approach, especially on her off-duty days.

The actress and Saturday Night Live alum tells PEOPLE exclusively that, if it’s up to her, she will spend exactly “zero minutes” on her hair.

“If I’m appearing somewhere on camera, I have a team of very talented stylists, a hairstylist, and a makeup artist who I’ve worked with for 10 years who are dear, dear friends of mine who do beautiful work that I love and I’m grateful for,” she says. “If left to my own devices, woof.”

She adds, “I’m so practical that it’s: Clean the mouth because that’s a healthcare issue and wash the face, because that’s an organ that you have to keep clean and then the rest I’m sort of like, eh.”

McKinnon, 40, says she has “other things to do” besides spend time on her own glam, because these days she is a “person of the woods,” since leaving her post at SNL and moving on to her next phase of life.

She did recently move out of the city (though still spends plenty of time in Manhattan, she says) and has turned her focus to other things — like creating the character Susan Toothbrush for Philips Sonicare’s latest ad campaign.

“Susan Toothbrush is a mythical woman who materializes through walls and helps people make better decisions about their oral health,” McKinnon says of the character she crafted for the brand, who appears in a couple of commercials. Susan appears in people’s bathrooms and encourages them to switch from a manual toothbrush to an electric toothbrush to support better oral hygiene.

“When Sonicare approached me about this collaboration, I was honored and I just wanted to take the opportunity to create a memorable character, which is what I try to do no matter what medium I’m working in,” she continues. “They were extremely collaborative and together we came up with Susan Toothbrush, who has her own mythology, and I’ve never gotten to play a character with her own mythology in an ad campaign.”

The Barbie actress tells PEOPLE that orthodontia was a struggle for her for many years while growing up — she didn’t lose her first tooth until she was 8, then she had braces as a teenager, and she even had a gap in her teeth for a while that she says was a bit traumatizing.

“I was at my junior prom with these gigantore clear braces,” she says. “It was so embarrassing.”

McKinnon jokes that in the quick clips of Susan Toothbrush, the actual “physics” of how she “materializes” are not truly explained, but she wants people to “develop fandoms” to help build out her story and mythology so the character can continue to live on beyond the small screen.
