About the Lab
Professor In Seok Han's research lab specializes in developing bio-inspired, eco-friendly cosmetic and dermatological formulations using natural marine and biological compounds. The lab focuses on harnessing bioactive molecules such as mycosporin-like amino acids (MAA) from symbiotic dinoflagellates (Symbiodinium) and phospholipid-based nanocarriers (e.g., PhS1P/PS) for enhanced skin delivery and protection. Key research directions include the development of natural sunblocks, advanced nanocarrier systems for transdermal delivery, and clinical evaluation of skin health improvements such as elasticity, thickness, and dermal density. The lab integrates biotechnology, dermatology, and pharmaceutical formulation to create sustainable, high-performance skincare solutions.

2Symbiodinium is a dinoflagellate genus that coexists with coral reefs and is known to provide ultraviolet (UV) protection in nature through the synthesis of mycosporin-like amino acids (MAA). In order to develop a natural and ecofriendly sunblock for use in summer resorts, the possibility of using a Symbiodinium microbiome extract or an MAA was investigated. Two sunblocks, one containing 7% Symbiodinium extract and the other containing MAA were prepared to be tested on hairless mice and human sk
목적: 모델 담즙산-PhS1P/PS 나노입자를 함유한 화장품 제형화 및 생체 내 효능을 평가하기 위하여 소수성인 담즙산의 주성분인 sodium deoxycholate 및 cholesterol과 lecithin을 기반으로 한 phytosphingosine-1-phosphate (PhS1P) 및 phytosterol (PS)을 효과적인 피부전달체로 개발하고자 한다. 방법: PhS1P 및 PS는 초음파 처리 방법에 의해 모델 담즙산-PhS1P/PS 나노입자에 봉입 되었다. 모델 담즙산-PhS1P/PS 나노입자의 피부침투율을 평가하기 위해 franz diffusion cell 실험을 수행하였고 원료에 대한 적용 가능성을 알아보았다. 모델 담즙산-PhS1P/PS 나노입자는 입도 분석기, SEM 및 HPLC 실험으로 특성을 분석하였고, 피부에 대한 효과를 확인하기 위하여 최종 시제품으로 임상평가를 진행하였으며, Cutometer 및 Dermascan-C를 사용하여 피부의 탄력, 피부의 두께 및
