Sir John (make-up artist)

In 2018, Sir John was responsible for Beyoncé's make-up during her performance at Coachella—dubbed "Beychella"—when she became the first black woman to headline the event. According to Sir John, he wanted Beyoncé to " look like a college girl on campus", a look that was inspired by the 1988 film School Daze.

That same year he partnered with Beyoncé to help create three looks for the pre-Grammy Roc Nation Brunch, 2018 Clive Davis Recording Academy Gala, and the 60th Annual Grammy Awards.

In 2016, Sir John designed Beyoncé's make-up for the Super Bowl 50 halftime show. Her make-up was lauded as an "insanely gorgeous coppery dream of a makeup look" by Cosmopolitan, "#flawless" by Glamour, and one of the "most memorable Super Bowl beauty moments" by Allure. During the Super Bowl 50 Halftime Show, Beyoncé announced her seventh concert tour, in support of her sixth studio album Lemonade, The Formation World Tour.

Sir John conceived and fine tuned her look for 49 sold-out shows, spanning 16 countries. The palette for The Formation World Tour consisted of warmer tones—bronze and terracotta shades. In alignment with Beyonce's 2016 Elle US, UK, and France magazine covers, Sir John focused on skin glow and naturalness.

In 2016, Sir John was crowned InStyle Makeup Artist of the Year.

In 2015, Sir John was named a creative director for L’Oréal Paris USA, making him the brand's first Black creative director in the United States. In 2022, he was tapped as Chief creative officer of CTZN Cosmetics.

In 2013, Sir John created Beyoncé's looks for the Beyoncé (album). Her self-titled fifth studio album is a two-disc album that includes an audio disc (disc one) and a "visual album" (disc two), where all 18 tracks are accompanied by non-linear short films. Among other videos for the album, he created Beyoncé's looks for two videos that accompanied the two-part tracks "Haunted" and "Partition." He also did her make-up in "Pretty Hurts," "Drunk in Love," "Blow," "No Angel," "Formation," "Jealous," "Rocket," "Mine," "XO," "Flawless," "Superpower," "Heaven," "Blue," and "Grown Woman."

In 2010, while on a lunch break, Sir John ran into his old friend Yadim Carranza—a make-up artist that he knew from his time at MAC and a lead assistant of British make-up artist Pat McGrath. This encounter led to an opportunity to work as a make-up artist under the wing of Pat McGrath—first in Bryant Park, New York City, and, shortly thereafter, during Milan Fashion Week. In Milan, Sir John served as a make-up artist at his first show ever, the Dolce & Gabbana fashion show. He also worked Prada's fashion show and, at Bulgari Hotel Milano, with his first celebrity client, Naomi Campbell.

Soon after working at Milan Fashion Week, Sir John began assisting British make-up artist Charlotte Tilbury. In September 2010, Tilbury introduced him to Beyoncé, at Tom Ford's first womenswear show during New York Fashion Week. At the Tom Ford show, Sir John made his debut as Beyoncé's make-up artist, at the same time that Beyoncé made her debut as a runway model. In 2012, Sir John signed an agreement with Beyoncé to become her make-up artist.
