Title: Jang-Hee Hahn: Innovator in Cosmetic and Pharmaceutical Compositions
Introduction
Jang-Hee Hahn is a notable inventor based in Chuncheon-si, South Korea. He has made significant contributions to the fields of cosmetics and pharmaceuticals, holding a total of 8 patents. His innovative work focuses on compositions that enhance skin health and address various dermatological issues.
Latest Patents
One of his latest patents is a composition comprising a P53-activating peptide. This invention provides a cosmetic composition aimed at inhibiting or improving seborrhea, as well as a pharmaceutical composition for preventing, improving, or treating the condition. The active ingredient, a specific peptide, significantly decreases the interaction between p53 and MDM2, thereby enhancing the interaction between p53 and RNA Polymerase II (POLII). This mechanism induces the expression of cytokines that lead to the apoptosis of sebocytes.
Another recent patent involves an SFRP5-derived peptide fragment and a cosmetic composition for skin whitening that contains this fragment. The peptide fragment, derived from secreted frizzled protein 5 (Sfrp5), is selected from a specific group of peptides. This composition effectively inhibits melanin formation in melanocytes, demonstrating an inhibitory activity against skin pigmentation. Additionally, it provides a reagent for researching or analyzing the inhibition of Wnt signaling pathways.
