ITZY's Yuna is Quadthera's brand model, after Dynafit and Infinix each made her a first
The home-care beauty device brand Quadthera has named Yuna of ITZY its official brand model. My Daily and Enet News reported it on 10 August 2026, the day the entry-level device 'Teenz' went on sale. Dynafit in 2025 and Infinix in 2026 had already made her a first model and a first ambassador.
What happened
The home-care beauty device brand Quadthera has named Yuna of ITZY its official brand model. My Daily and Enet News reported it on 10 August 2026, writing that Quadthera would put out photo shoots and campaign content with Yuna and launch an entry-level home-care beauty device called ‘Teenz’.
According to Enet News, the brand message the campaign carries is ‘For your timeless youth’ and the brand’s slogan is ‘The First Routine for Your Skin’. The same outlet described Quadthera as a brand that has built water-droplet ultrasound home-care devices on 30 years of ultrasound engineering.
Vegan News reported the same day that ‘Teenz’ had gone on sale. A representative of the manufacturer Eco DM Lab told the outlet: “We concentrated on keeping it light and intuitive while carrying Quadthera’s water-droplet ultrasound engineering and know-how.”
Why is it trending?
Two brands had put Yuna in a first seat before this one. The Korea Economic Daily reported on 27 March 2025 that the sports brand Dynafit had chosen her as its first female model and released a film for the 2025 spring-summer season. The campaign slogan was ‘Now Begin’, and the same report carried its line: “Because today’s resolve and today’s movement become tomorrow’s you.” Yuna fronted the Dynafit Womens line, which the brand pitches for everyday wear and for training. A Dynafit representative told the outlet: “Starting with the release of the campaign film with Yuna, we will roll out activity to strengthen the Womens line in earnest,” and Market Economy Newspaper reported that the brand released the campaign’s photo shoot on 1 April and would widen its Womens range.
A year on, Ten Asia reported on 3 March 2026 that the global technology brand Infinix had chosen Yuna as its first global ambassador. Yuna said at the time: “I am glad to be able to show my true self as an Infinix global ambassador.”
