The actress, who starred in Disney's The Descendants series and Freeform's Pretty Little Liars: The Perfectionists, has been a long-time fan of the brand.
"Since I can remember, one of my favourite places in the world was my mum's vanity, where I discovered my love of fashion, beauty and the perfect red Revlon lipstick." Carson said.
"I wore it at my very first dance recital, performance and dance competition after that. I felt invincible on stage in my red lipstick, like I could do, and be anything.
"I'm so proud to join the other incredible Revlon ambassadors who inspire me and countless other women around the world."
Carson's first campaign for Revlon's ColorStay Foundation, Super Lustrous Lipstick and ColorStay Eyeliner will debut in Autumn 2020.
She joins the likes of fellow actress Gal Gadot, along with Ashley Graham, Adwoa Aboah and Eniola Abioro who are already representing Revlon.
