The 'It Guy' Jimin Effect: Is K-Beauty Reshaping Its Buying Rules?

As of August 2026, the K-Beauty market is driven by two key forces: the immense purchasing power of the global K-Culture fandom and the ongoing demand for high-performance skincare. The fandom economy is expanding beyond idol merchandise to include 'it items,' while consumers also seek essential benefits like UV protection, skin barrier strengthening, and anti-aging. These coexisting needs are fueling the complex growth of the market. Brand managers, distributors, and OEM/ODM partners must understand these dual trends to formulate effective strategies.

K-Culture's global influence directly impacts the K-Beauty market. Notably, the phenomenon of K-Pop idols' fashion items selling out worldwide demonstrates that fandom's purchasing power extends beyond simple merchandise consumption to encompass their entire lifestyle. For instance, as of August 3, 2026, news of BTS member Jimin (지민)'s Dior sweater selling out proved the influence of a 'global it-guy' via TikTok. This phenomenon can be applied to beauty products as well; the immediate fan reaction to products worn or recommended by idols presents enormous opportunities for brands.

At the same time, consumers' focus on the essential efficacy of products remains strong. Musinsa (무신사) Beauty ranking data suggests that products emphasizing clear functionalities like UV protection, skin barrier improvement, and anti-aging consistently rank high. This indicates that K-Beauty must possess product strength based on scientific efficacy, moving beyond mere trends.

An analysis of products ranking high on Musinsa (무신사) Beauty as of August 3, 2026, revealed a strong showing for functional skincare and products targeting specific needs. Product categories emphasizing clear benefits such as UV protection, skin barrier strengthening, anti-aging, and moisturizing/brightening sheet masks were particularly prominent.

Notable brands in the Musinsa (무신사) rankings include Layerlab and Olicell. Layerlab gained consumer preference with its 'High-Function Barrier Balance Duo,' consisting of Niosome Panthenol 5% Serum and Retinol Serum, appealing with clear functionalities like skin barrier strengthening and anti-aging. This demonstrates the effectiveness of developing products that emphasize the synergistic effects of specific ingredient combinations. Olicell made its presence known in the sheet mask market with its 'Collagen Cream Mask,' promoting a large volume alongside collagen and brightening effects. These examples suggest that a strategy focusing on specific ingredients and benefits, while also offering good value for money, is effective in online channels.

Biotherm's UV Defense product and Clio's (클리오) Crystal Glam Balm have also solidified their positions as steady sellers, offering essential UV protection and color payoff beyond daily lip care, respectively. These brands consistently maintain their market share based on strong product quality and brand recognition.

Considering the complex trends in the current K-Beauty market, the following strategic approaches are necessary:

1. Strengthen Fandom Marketing and Explore Collaboration Opportunities (Brands, Distributors): Brands should leverage the purchasing power of fandoms and increase product awareness through collaborations with K-Pop idols and influencers. Beyond simple model contracts, 'culture collaborations' that actively link an idol's image and story to product development and marketing are crucial.
2. Focus on Developing High-Performance Ingredient-Based Products (OEM/ODM, Brands): Concentrate on developing high-performance skincare products utilizing proven effective ingredients such as panthenol, retinol, and collagen. Crucially, differentiate product strength by researching optimized ingredient combinations and formulations tailored to consumer needs.
3. Establish Customized Strategies for Each Online Channel (Distributors, Brands): Continuously analyze ranking data from major online platforms like Musinsa (무신사) and implement product configurations and promotional strategies suited to each platform's core consumer base. Developing online-specific products, such as large-volume items and special sets, is particularly important.
4. Proactively Respond to Global Regulations and Market Trends (OEM/ODM, Brands): As K-Culture's popularity accelerates expansion into overseas markets, it's essential to consider global standards from the product planning stage, based on an understanding of regulatory changes in key countries such as FDA, EU 1223/2009, and NMPA.

K-Beauty will achieve sustained growth by simultaneously targeting both the fandom economy and functional skincare. Accurately reading market trends and responding swiftly will be key to success.
