Oh K!

Oh K! is a British skincare brand built around Korean beauty (K-beauty), based in London and best known for its sheet and hydrogel face masks. The company describes its approach as ingredient-driven and rooted in Korean formulation, and it sells across the UK, Europe and North America through retailers such as Sephora, Ulta Beauty, Boots, Douglas, H&M and iHerb. As of 2026 the brand is active, with a current e-commerce site and ongoing retail distribution.

The brand sits at the intersection of two places: a UK company that develops and markets the range, and South Korea, where the products are made. Editorial coverage notes that Oh K! arrived "before K-Beauty started making waves in the west," positioning it as an early entrant in the trend's spread to Western markets [7].

Accounts of the brand's start differ slightly on dates. Two editorial sources record that Oh K! was established in 2014 [7], while the trade publication Cosmetics Business dates the range's retail launch to 2015 and describes it as "inspired by a trip to Seoul way back in 2014" [5]. The most consistent reading is that 2014 marks the brand's founding and inspiration, with 2015 as the commercial launch. The brand's own website does not state a founding year. The names of its founders are not publicly recorded in available sources.

From the outset the company drew on Korean expertise rather than Korean ownership. According to one editorial profile, the team "partnered up with their R&D team in Seoul, South Korea and developed their first collection of solution and lifestyle driven masks," later expanding from masks into full skincare routines [7]. This split — a London-based brand company paired with Korean research and manufacturing — is a defining feature of how Oh K! is built.

Oh K! operates under Natural Products Worldwide (NPW), a fact stated in the brand's own privacy policy, which names the company as the data controller "under the umbrella of Natural Products Worldwide" [4]. Independent coverage corroborates this, with one reviewer referring to "NPW's Oh K! range" [6]. A trade-directory listing on Cosmetics Business instead records the company as Vivona Brands [5] — understood to be the same group under a later holding name. The brand's registered office is in Putney, London.

The brand frames itself as an ingredient-led interpretation of K-beauty. "At Oh K! our ingredient-driven philosophy is rooted in the innovation and expertise of K-beauty," its site states, adding that it prioritises "high performance actives that are both trend-forward and innovative." The stated mission is to "deliver clean, effective skincare powered by advanced ingredients and proven formulations." Oh K! also leans on a playful identity, using the coined term "skindividuality" and the tagline "Glow The K Beauty Way."

Three values anchor the brand's self-description: happiness, sustainability and authenticity. On the last point, the company says it does not retouch skin in its photography, framing this as "keeping it real and embracing imperfections."

The range centres on masks. Its signature product is a sheet mask made from soft bamboo fibre, soaked in skincare essence to lock in moisture, and the line extends to hydrogel, eye, lip and foot masks alongside broader skincare. One reviewer described a three-in-one product combining a cleansing wash, a moisturising serum and a bamboo-charcoal fibre mask. Products carry a "Crafted in Korea" mark, and the brand states it is cruelty-free.

On formulation, the company says it works "to EU standards, banning over 1,350+ ingredients" and describes its products as consciously created [2]. Hero ingredients and proprietary technologies are not detailed in available sources.

Oh K! won the Body, Bath and Spa category at the Gift of the Year Awards in 2017 [5]. The following year it released the Pink and Marine Edit, described as a summer 2018 launch aimed at brightening, purifying and hydrating the skin [5]. Cosmetics Business has profiled the brand as an award-winning K-beauty range whose design and ingredients are shaped by South Korea.

The brand is trading as of 2026. It maintains an active e-commerce site with current stockists including Sephora, Ulta Beauty, Boots, Douglas, H&M and iHerb, runs the "Glow The K Beauty Way" campaign, and is active on Instagram and TikTok under the handle @ohk_life.
