Korean Citrus Varieties Gain Recognition for Skin Barrier Improvement in Cosmetics

The Rural Development Administration (RDA) announced on the 10th that it has developed functional cosmetics containing two local citrus varieties, 'Winter Prince' and 'Onjumilgam,' which are accredited for their skin barrier improvement properties. This venture underscores the potential of these citrus fruits as new industrial materials, aimed at enhancing market demand and offering natural alternatives amid rising consumer interest in clean beauty products.

Citrus fruits play a crucial role in skin health by providing essential proteins and collagen that are vital for maintaining a strong skin barrier. With a decline in the expression of these proteins often leading to dryness, itching, and inflammation, the development positions these citrus varieties as a solution in the cosmetic segment—a market increasingly leaning towards natural ingredients. By leveraging the stability and availability of domestic citrus production, the RDA aims to fulfill the growing demand from cosmetic companies for sustainable raw materials.

The 'Winter Prince' and 'Onjumilgam' varieties are noted not just for their aesthetic appeal reminiscent of Jeju's clean environment, but also for their rich content of flavonoids and polyphenols, which provide antioxidant, anti-inflammatory, and anti-aging benefits. These properties have been validated through recent studies demonstrating significant increases in gene expression levels of crucial proteins such as filaggrin and collagen—key indicators of skin barrier enhancement, making them attractive options for brand portfolios seeking differentiation.

Conducted by a collaborative team from RDA, Jeonnam Bio Industry Promotion Agency, and industry partner Farmsville, the research indicates impressive results from the mixed extract application on artificial skin. The increased gene expression was achieved at nearly twice the level of the control group, correlating with positive outcomes observed in adult trials over four weeks, which revealed a 15.4% reduction in transdermal water loss and a 61.7% increase in skin moisture levels, alongside a 28.5% improvement in itching.

The functional citrus cosmetics utilizing 'Winter Prince' and 'Onjumilgam' are set to be officially certified by the Ministry of Food and Drug Safety in April, a pivotal move likely to enhance market validation and consumer trust. This approval signals a strategic entry point for domestic producers innovating in the cosmeceutical landscape, where regulatory backing often translates into competitive advantages.

Farmsville plans to initiate extensive product manufacturing starting in November, reflecting an industry-wide shift towards utilizing local agricultural innovations in beauty formulations, benefiting both farmers and manufacturers. According to Kim Jin-suk of RDA's National Horticultural Science Institute, employing 'Winter Prince' as a cosmetic ingredient could significantly increase citrus farmers' incomes while expanding the distribution of this new variety.

Looking ahead, the RDA expresses intentions to broaden research to include functional foods and other bio-materials, indicating a forward-thinking approach that aligns with emerging trends in the beauty and wellness sectors. This expansion not only demonstrates adaptability to consumer preferences but also solidifies the agricultural base's role in the evolving landscape of beauty products.
