미용기능식품은 최근 이너뷰티식품으로도 일컬어지며, 일시적이고 인위적인 방법이 아닌 음식 섭취를 통해 건강과 아름다움을 가꿀 수 있는 식품이다. 기존에 이너뷰티식품은 건강기능식품 중 하나로 인식되었으나 천연재료의 미용효과를 강조한 다양한 식품들이 출시되면서 점차 이너뷰티 식품군이 확대되고 있는 추세이다. 국내에서는 자생식물과 약용식물을 함유한 건강즙, 디톡스음료, 착즙 주스 등의 제품이 항산화 및 피부건강과 같은 마케팅 진행으로 인기를 얻고 있다. 그러나 아직 이너뷰티식품 기업 대부분이 안정적인 매출과 인지도를 구축하지 못하고 있는 상황이며, 대체적으로 중견기업 이상의 기업들이 점유하고 있는 상황이므로 인지도가 낮은 브랜드들은 적극적인 수출활동을 진행하지 않고 있다. 한편 전 세계적으로 이너뷰티식품의 카테고리가 다양화되고 타깃 소비층이 증가하고 있으므로, 적절한 제품 및 마케팅 전략 수립을 통해 시장을 확대해가는 전략이 필요한 상황이다. 따라서 본 기고에서는 이러한 이너뷰티제품의 소재 및 연구방향, 시장동향들을 소개하고자 하며, 이를 통해 이너뷰티식품이 향후 발전해 나아갈 방향을 제시하고자 한다.

This study focused on the preparation and characterization of anti-wrinkle peptides from the salted and fermented shrimp (Acetes japonicus) inoculated with Salinivibrio cibaria BAO-01 (SFSC). The results showed the proximate composition of SFSC to be 9.23% water, 75.32% protein, 0.23% fat, and 13.3 mg/g ash. Interestingly, the S. cibaria fermentation significantly increased the amount of methionine, leucine, and arginine. The in vitro antioxidant activity was assayed by the diphenylpicrylhydrazyl method and its IC₅₀ value was found to be 43.02±2.84 ㎍/mL. It was observed to inhibit the activity of elastase, tyrosinase, collagenase, and hyaluronidase. The IC₅₀ values of SFSC were 182.75±12.38 ㎍/mL for anti-elastase activity, 186.78±7.95 ㎍/mL for anti-tyrosinase activity, 444.4±34.81 ㎍/mL for anti-collagenase activity, and 1447.95±28.92 ㎍/mL for anti-hyaluronidase activity. These results suggest that salted and fermented shrimp has strong potential for the development of nutricosmetic products.

The beneficial effects of probiotics are now widely reported, although there are only a few studies on their anti-aging effects. We have found that Lactobacillus plantarum HY7714 (HY7714) improves skin hydration and has anti-photoaging effects, and in the present study, we have further evaluated the anti-aging effect of HY7714 via a randomized, double blind, placebo-controlled clinical trial. The trial included 110 volunteers aged 41 and 59 years who have dry skin and wrinkles. Participants took 1 × 10¹⁰ CFU/day of HY7714 (probiotic group) or a placebo (placebo group) for 12 weeks. Skin hydration, wrinkles, skin gloss, and skin elasticity were measured every 4 weeks during the study period. There were significant increases in the skin water content in the face (p < 0.01) and hands (p < 0.05) at week 12 in the probiotic group. Transepidermal water loss decreased significantly in both groups at weeks 4, 8, and 12 (p < 0.001 compared with baseline), and was suppressed to a greater extent in the face and forearm in the probiotic group at week 12. Volunteers in the probiotic group had a significant reduction in wrinkle depth at week 12, and skin gloss was also significantly improved by week 12. Finally, skin elasticity in the probiotic group improved by 13.17% (p < 0.05 vs. controls) after 4 weeks and by 21.73% (p < 0.01 vs. controls) after 12 weeks. These findings are preliminary confirmation of the anti-aging benefit to the skin of L. plantarum HY7714 as a nutricosmetic agent.
