Viral TikTok brand TIRTIR is taking on the UK beauty market and here's how

K-beauty sensation TIRTIR, best known for its viral Mask Fit Red Cushion Foundation, has officially launched on Sephora.co.uk, marking a major step in its UK expansion strategy. A wider in-store rollout at Sephora is planned for later this year.

The Seoul-based brand is already stocked at Boots and Lookfantastic, where its hero products have steadily gained traction among British consumers seeking out the next generation of glow-giving, skin-first beauty. But its presence on Sephora UK signals the brand’s move into more mainstream beauty consciousness.

Founded on a skincare-first philosophy, TIRTIR has tapped into the growing global demand for hybrid beauty products. Its signature Mask Fit Red Cushion has drawn particular attention for its unique texture, long-wear finish and dewy-but-set glow.

TIRTIR’s UK momentum reflects a broader appetite for not only Korean beauty, which has transitioned from niche cult favourite to major category driver in global markets, but also skincare-first cosmetics. Cushion foundations, originally developed in South Korea, exemplify that skin-meets-makeup sweet spot. Plus, unlike many K-beauty brands, TIRTIR promises shade inclusivity with its 30-strong shade range.

Joining the foundation in the brand’s growing UK range are the Waterism Glow Tint, Ceramic Milk Ampoule and Milk Skin Toner - all designed to deliver hydration and luminosity, while reinforcing the brand’s "your skin, but better" aesthetic.

With partnerships with Boots, Lookfantastic and now Sephora, plus an in-store debut expected later in 2025, TIRTIR is fast becoming one of the most visible K-beauty brands in the UK.
