Abstract:
A cosmetic composition for reducing an edema is provided to reduce an edema using gourd extracts, gingko leaf extract, question plant extracts, extract of chlorella, citrus extracts and caffeine. A cosmetic composition for reducing an edema comprises one or more ingredients selected from a group consisting of a Lagenaria siceraria var. gourda extract and a Helichrysum Italicum extract as an active ingredient. The cosmetic composition additionally contains one or more ingredients selected from a group consisting of gingko leaf extract, extract of chlorella, a citrus extract and caffeine. The coating method of the cosmetic composition for reducing the edema includes a step of compressuring skin using one of a roller, an acupressurer and a massage unit before coating the cosmetic composition. A skin-applicating apparatus contains the cosmetic composition and is one of the roller, the acupressurer and the massage unit.
Abstract:
본 발명은 피부 각질 박리량을 정량할 수 있는 평가법으로서, 기존의 형광염색을 통해 육안적으로 각질 박리량을 평가하는 부분을 개선하여 이미지 분석 프로그램을 이용함으로써 각질박리량을 수치화하고, 객관적으로 각질 박리량을 검증할 수 있는 방법에 관한 것이다. 보다 상세하게는 피부 표면의 각질층을 형광염색시약으로 염색한 다음, 형광염색된 피부 표면에 각질 박리용 시료를 도포한 후 사진을 촬영하여 형광이미지를 얻음으로써 추적 관찰을 실시하고, 촬영한 사진의 형광이미지는 이미지 분석 프로그램을 이용함으로써 형광강도를 수치화하고, 형광이미지를 이용하여 3차원 이미지화 할 수 있다. 이를 통해 기존의 육안 판정에 의존하던 각질 박리 평가를 수치적으로 객관화 할 수 있으며, 3차원 이미지 변환을 통해 각질 박리 효과를 가시화 할 수 있다. 각질 박리, 형광염색, 댄실 클로라이드(Dansyl chloride), 디히드록시아세톤(Dihydroxyacetone), 이미지 분석, 형광강도, 흑백 전환
Abstract:
A method for measuring the amount of human stratum corneum exfoliation is provided to digitize the stratum corneum exfoliation amount using an image analysis program by improving a conventional technique of evaluating the stratum corneum exfoliation amount visually through fluorescence staining, thereby verifying the stratum corneum amount objectively. A method for measuring the amount of human stratum corneum exfoliation comprises the steps of: (a) coating a fluorescent staining sample such as Dansyl chloride and dihydroxyacetone on a stratum corneum of skin surface for fluorescence-staining; (b) coating a sample for exfoliation such as glycolic acid, lactic acid, malic acid, citric acid, tartaric acid, salicylic acid and papain enzyme on the fluorescent-stained stratum corneum for 4-14 days to perform exfoliation; (c) fluorescence-photographing the exfoliated stratum corneum to obtain a fluorescent image; and (d) setting up an analysis area of the fluorescent image and digitizing fluorescence strength of the analysis by using an image analysis program. Further, the step (a) of coating a fluorescent staining sample is performed for 6 hrs.
Abstract:
A 4-substituted benzoic acid derivative compound having 3,4-methylenedioxybenzene or 3,4-ethylenedioxybenzene moiety is provided to promote the biosynthesis of main constituents of skin dermis such as collagen, elastin, fibrillin, glycosaminoglycan(GAG) closely related to skin wrinkles, thereby being usefully used as medicines and skin external applying agents for preventing aging and improving the wrinkles. An anti-aging cosmetic composition comprises 0.01-20.0 wt.% of a 4-substituted benzoic acid derivative compound having 3,4-methylenedioxybenzene or 3,4-ethylenedioxybenzene moiety and represented by the formula(I), wherein R1 is -CH2- or -CH2=CH2-, R2 is the structural formula(Ia), and R3 is H, methyl or ethyl. A method for preparing the 4-substituted benzoic acid derivative compound comprises the steps of: (a) preparing a compound(1) represented by the formula(1) from 3,4-methylenedioxybenzoic acid or 3,4-ethylenedioxybenzoic acid; and (b) hydrolyzing the compound of the formula(1) with a base to prepare a compound(2) represented by the formula(2).
Abstract:
A system for measuring the in-vitro water resistance SPF of a sunscreen agent and a method for measuring the SPF by using the same are provided to predict the water resistance degree of a product without performing an actual clinic test. A system for measuring the in-vitro water resistance SPF of a sunscreen agent includes a drive section(10), and a rotary blade(20). The drive section includes a rotational shaft(11). The rotational shaft is submerged in the water in a washing tub. The rotary blade is installed at one end of the rotational shaft. An ultraviolet sunscreen agent is coated on a surface of the rotary blade. The ultraviolet sunscreen agent is washed out in the water by rotating the rotary blade driven by the drive section. The rotary blade has a plurality of blade ribs(22) extended vertically at one end of the rotational shaft, and substrates(24) coated with the ultraviolet sunscreen agent.
