It’s official: this is Taylor Swift’s Eras Tour lip combo.

For many of us, longevity is a non-negotiable requirement when it comes to lip makeup. We need formulas that can keep up with our hectic routines and require only occasional touch-ups. And in this regard, we can rely (a lot) on Taylor Swift. Just remember how the Nashville native sang, danced, and ran around the stage for over three hours during her The Eras Tour concerts with a perfect vermilion lip. For months, the talk of social media was constant: what could withstand such a marathon (sometimes even in the rain)? Now, finally, we have the answer.

The revelation came courtesy of The End of an Era, the Disney+ documentary series in which the artist meticulously details the process behind her most ambitious tour. And during the latest episode, amidst rehearsals, creative moments, and never-before-seen footage, the exact products that make up her famous lip combo were revealed .

Red lips have been an inseparable part of Swift’s image for over a decade. She’s worn them since her early twenties, following the release of her third studio album, Red, and hasn’t gone without them since. Over the years, she’s declared herself a fan of MAC’s iconic Ruby Woo lipstick, and Pat McGrath even created The Taylor Made, a lip kit designed specifically for the singer. And while she’s used all these options—and even strayed from reds to embrace peach tones during the promotion of The Life of a Showgirl, her latest album—today we know which lipsticks she wore during The Eras Tour.

In the docuseries, the artist subtly reveals that she relies on two essential products. Swift is seen lining her own lips while looking in the mirror at Charlotte Tilbury’s Airbrush Flawless Finish compact powder (which she likely uses to set all her makeup), and using Smashbox’s Be Legendary lip liner. This scene quickly went viral, as it’s surprising to see a star of her caliber calmly preparing minutes before facing an audience of over 50,000 people. The final touch is applied by her makeup artist, who uses MAC’s Locked Kiss ultra-matte lipstick. To be more precise, she uses the shade Ruby True, a revamped, more resistant, and longer-lasting version of the iconic Ruby Woo mentioned in the previous paragraph.
