Abstract:
PURPOSE: A composition containing plant extract having different irritation relief mechanism is provided to suppress prostaglandin-E2 and activate secretion of alpha-melanocyte stimulating hormone. CONSTITUTION: A composition for relieving skin irritation and inflammation contains Rubus Idaeus fruit extract, Mentha piperita extract, and Boerhavia diffusa Root Extract as an active ingredient. The weight ration of the mixture is 1-4:1-8:1-8. The active ingredient relieves skin irritation and inflammation by retinoic acid or sldium lauryl sulfate. The composition is used in the form of an external use skin formulation. The composition is used in the form of skin, lotion, massage cream, nutrition cream, pack, gel, or skin additive cosmetic.
Abstract:
PURPOSE: A cosmetic composition containing Glechoma hederacea extract, peppermint extract, and biosaccharide gum-2 is provided to protect skin from outer irritation and to normalize sensitive skin. CONSTITUTION: A cosmetic composition for relieving irritation contains 0.01-5 weight% of mixture perppermint extract and biosaccharide gum-2 as active ingredients. The cosmetic composition is used in the form of skin, lotion, massage cream, nutrition cream, pack, gel, ointment, gel, cream, patch, or spray. The cosmetic composition further contains active ingredients for skin whitening, anti-aging, or anti-wrinkle.
Abstract:
PURPOSE: A biomarker of which expression is specifically decreased or suppressed in the sensitive skin is provided to quickly diagnose sensitive skin and used for screening a relieving agent. CONSTITUTION: A biomarker for diagnosing sensitive skin contains gene of which expression is decreased or increased in the sensitive skin compared to healthy skin or a protein encoding the gene. A method for screening a relieving agent of sensitivity comprises: a step of conjugating a candidate agent to a protein encoded by a gene of which expression is increased or decreased in the sensitive skin; and a step of confirming the suppression of protein activity.
Abstract:
A method for calculating a dangerous level of skincare claim and an information providing system thereof are provided to determine precisely and grade the dangerous level of the skincare claim caused by cosmetics, analyze the skincare claim easily in real-time, and transfer an analysis result quickly to a related department. A receiver(10) receives skincare claim from customers and manages a one-time skincare side effect claim, and a main server(20) communicates with the receiver through the network. A database(30) stores product information, consultation information, a score of each monitoring item, a skincare side effect score, a skincare side effect claim ratio, and management information of each dangerous level. An analysis system(40) includes an algorithm scoring the skincare side effect claim based on the score of each monitoring item and the consultation information, an engine calculating the skincare side effect claim ratio based on the consultation and product information, and a matrix grading the dangerous level from the skincare side effect score and the skincare side effect claim ratio according to a fuzzy logic. A related department(50) receives the management in an alarm type according to the dangerous level from the main server.
Abstract:
A cosmetic composition containing the extract of Mentha Piperita for reducing skin irritation caused by retinoid is provided to inhibit expression of inflammation-causing materials such as ICAM-1 (intercellular adhesion molecule-1) and IL-1alpha(interleukin-1 alpha) factor. The cosmetic composition for reducing skin irritation and inflammation caused by retinoid contains 0.1-1 wt.% of the extract of Mentha Piperita which inhibits expression of IL-1alpha factor, and erythema and edema formation responses irritated by retinoid, wherein the retinoid is retinol, retinal or retinoic acid; and the Mentha Piperita extract contains 0.9-1.8 g/l of polyphenols having antioxidizing effects.
Abstract:
본 발명은 피부자극 및 염증을 완화시키는 효능을 갖는 민감성 화장료 조성물에 관한 것으로, 보다 상세하게는 수박(Citrullus Vulgaris) 내피 추출물을 함유함으로써, 레티놀 및 자외선 자극에 대항하여 피부 세포에서 염증매개인자인 인터페론-γ에 의한 ICAM-1의 발현 및 IL-1α, TNF-α 및 IL-8의 생합성을 억제하는 것을 통해, 자극완화 기능 및 사이토카인(cytokine)의 생성 조절기능에 의해 민감성 피부를 개선하며 이들을 환경에 적응하도록 하는 효능이 뛰어난 민감성 피부용 화장료 조성물에 관한 것이다.
