Patent number: 11185488Abstract: A skin external composition containing 1,2,3,4,6-penta-O-galloyl-?-D-glucose (hereinafter referred to as “PGG”) and its use to improve moisture balance of skin are disclosed. The skin external composition, due to containing PGG, stimulates the formation of filaggrin in keratinocytes, increases loricrin and involucrin expression, thereby stimulating the formation of a normal keratin layer, and as a result, can strengthen the skin barrier function to provide an excellent skin moisturization improving effect. Thus, the composition is effective in improving moisture balance of skin. A method for moisturizing the skin using the composition is also disclosed.Type: GrantFiled: July 31, 2018Date of Patent: November 30, 2021Assignee: Amorepacific CorporationInventors: Kyu Han Kim, Eui Dong Son, Jin Sup Shim, Tae Ryong Lee

Patent number: 10533992Abstract: Unlike a conventional method for evaluating a degree of ultraviolet protection through visual evaluation, the disclosed method for measuring a sunlight protection function can accurately and objectively measure and determine a degree of sunlight protection by measuring a change due to a material to be measured with respect to an expression amount of skin tissue antimicrobial peptides (AMPs) in skin cells, which decrease from exposure to sunlight, and/or a generation amount of S-nitrosylated protein. Additionally, the disclosed measurement method can determine whether blue/violet light of wavelengths of 400-500 nm, which induces the most skin damage among visible rays, is blocked and provide a more specified sunlight protection effect evaluation result. Moreover, by using the disclosed measurement method, a degree of sunlight protection can be indexed, and a sunlight protection composition for protecting normal skin from the blue/violet light can be provided.Type: GrantFiled: March 19, 2015Date of Patent: January 14, 2020Assignee: AMOREPACIFIC CORPORATIONInventors: Hyoung June Kim, Min Sik Choi, Ji Yong Jung, Ju Yearl Park, Tae Ryong Lee, Dong Wook Shin, Eui Dong Son, Min Jung Chae
