Beauty review: Why I love TIRTIR’s TikTok viral foundation, and you will too

Back in June when she was invited to host the 78th Annual Tony Awards, it was Cynthia Erivo's glowing skin and fluttery lashes that really took centre stage. She went through a number of killer outfit changes, but it was a flawless base courtesy of TIRTIR’s viral Mask Fit Red Cushion that grabbed my attention, and I’m not alone.
After a little research I discovered that her MUA, Joanna Simkin reached for several products from the K-beauty brand, which was founded back in 2017 by influencer Lee Yoo-bin and has since become a global phenomenon. A personal fave of mine, the TIRTIR Milk Skin Toner was used as an essential first step to lock in hydration, followed by the Ceramic Milk Ampoule for an extra hit of nourishment and glow. Then, the viral Mask Fit Red Cushion in shades 43N and 45W was key to creating Cynthia’s flawless base, and ensured that her dreamy full coverage, semi-matte finish stayed fresh and lasted all night long.

It was the foundation formula’s longevity plus super flattering finish that had me hooked from the moment I popped the lid on my very first delivery, and since then I’ve been singing its praises to everyone I meet in search of a full coverage face base that feels good and lasts.

Much more than just viral moment
The Mask Fit Red Cushion foundation first found fame outside Korea on TikTok, where it has been positively reviewed literally hundreds upon hundreds of times. Fans like me point to its impressive pigment and flawless, natural-dewy finish as to why it’s so beloved: it impressively covers any unwanted spots, redness, or inflammation, while still managing to look skin-like. And to the surprise of many, it’s a bit of a game-changer for acne too.
Its excellent coverage and lightweight texture have made it particularly popular for covering blemishes and breakouts while blurring pores, and I personally love that it still allows skin to breathe, so never feels heavy or suffocating. This is mainly thanks to its unique formulation, which contains what team TIRTIR likes to call "air-layered powders”. Unlike regular powders, air-layered powders are designed to be exceptionally lightweight with a lower density, which allows them to absorb excess oil while maintaining breathability, ensuring skin feels comfortable, fresh, and non-heavy throughout wear.
The mix of full coverage and a natural, semi-matte finish make it the dream for wearing day into night, while the lightweight formula blends seamlessly for that glass skin finish we all want at any age. And thanks to the sponge that comes in the compact along with it, after you’ve nailed the application method it can literally be applied in minutes – I’ve got my full TIRTIR face down to just sixty seconds, which is the actual dream when I’ve got an early start.

The takeaway
Delivering a promised 72-hours of flawless, hydrating coverage and available in 40 inclusive shades (with more to come), I can’t get enough of the lightweight, dermatologist-tested formula that has proven to be the Holy Grail full-coverage foundation for makeup lovers the world over.

I love it, and I think you will too. You can grab your TIRTIR here.
