Abstract:
PURPOSE: A cosmetic composition which enhances skin rebirth is provided to enhance cell activation and to improve anti-wrinkle and elasticity. CONSTITUTION: A skin cosmetic composition contains 0.1-10 weight% of octacosanol and 0.1-30 weight% of Lepidium meyenii extract as an active ingredient. The octacosanol and Lepidium meyenii extract is mixed in a weight ratio of 1-9:9-1. The Lepidium meyenii extract is isolated using ethanol. The cosmetic composition is used in the form of skin, lotion, massage cream, nutrition cream, pack, gel, or ointment, patch, or spray.
Abstract:
A cosmetic composition is provided to promote collagen biosynthesis by comprising alpha-ketoglutarate increasing the prolidase activity involving with the supply of proline, a main constituent amino acid of the collagen, together with alpha-lipoic acid increasing the expression of prolyl-4-hydroxylase to make a generated pro-collagen form a right triple helix. A cosmetic composition for improving skin wrinkle comprises 0.001-10 wt.% of alpha-ketoglutarate as an effective ingredient. The composition further comprises 0.001-10 wt.% of alpha-lipoic acid.
Abstract:
A skin external composition comprising a cathepsin G inhibitor is provided to prevent an adhesion protein from being degraded by intrinsic aging and photo-aging, reduce the production of metalloproteinase and inhibit the activity of metalloproteinase, thereby being more potent anti-aging substance than existing anti-aging substances. A method for screening anti-aging materials is provided to develop the anti-aging materials which effectively inhibit the quantitative and qualitative increase of metalloproteinase, resulting from the degradation of an adhesion protein by cathepsin G in skin cells without direct UV irradiation. A skin external composition for preventing skin aging comprises 0.01-10 wt% a cathepsin G inhibitor as an effective ingredient, wherein the cathepsin G inhibitor is at least one selected from the group consisting of compounds represented by formulae(1) to (4). The composition is formulated into skin lotion, astringent lotion, milk lotion, nourishing cream, essence, massage cream, eye cream, pack, body lotion, body cream, body oil or body essence. A method for screening an anti-aging material comprises the steps of: (a) adding an anti-aging candidate material to a substrate in the presence of cathepsin G enzyme; and (b) measuring the inhibition of activity of the cathepsin G enzyme. Further, the measure of the inhibition of activity of the cathepsin G enzyme is performed by measuring a concentration of a produced metalloprotease.

본발명은α-케토글루타레이트(α-ketoglutarate)를함유하는주름개선용화장료조성물에관한것으로, 보다상세하게는α-케토글루타레이트가콜라겐의주요구성아미노산인프롤린의공급에관여하는프롤리다아제활성을증가시킴으로써콜라겐생성을촉진시키는주름개선용화장료조성물에관한것이다. 또한, 본발명에의한화장료조성물은상기α-케토글루타레이트와함께α-리포익산(α-lipoic acid)을유효성분으로더 함유할수 있으며, 상기α-리포익산은프롤릴-4-수산화효소발현을증가시켜생성된프로콜라겐이올바른삼중나선(triple helix)을형성시키는역할을한다. 즉, 본발명에의한화장료조성물은프롤리다아제활성을증가시키는α-케토글루타레이트와함께α-리포익산을함유함으로써콜라겐생합성을촉진시킨다.
Abstract:
PURPOSE: A cosmetic composition containing red algae is provided to regenerate epidermis and dermis on the skin and to improve anti-wrinkling with high safety. CONSTITUTION: A cosmetic composition for anti-aging contains 0.0001-25 wt% of red algae extract as an active ingredient. The red algae include Gelidium amansii, Gracilaria, gigartina, laver, Acanthopeltis japonica, gracilaria, Ceramium kondoi graphite or Grateloupia Filicina. The cosmetic composition is manufactured in the form of an emulsion, suspension, microemulsion, microcapsule, microgranule, or vesicle dispersion agent of ion type(liposome) and non-ion type.
Abstract:
PURPOSE: A method for evaluating skin elasticity enhancement using corium mimic is provided to observe binding force between fibroblast and collagenous fiber. CONSTITUTION: A method or evaluating skin elasticity enhancement using corium mimic comprises: a step of preparing a saccharification collagen control group and a saccharification experimental group; a step of mixing fibroblasts to the control and experimental groups each to prepare gel; a step of constructing three-dimensional form using a culture insert; a step of putting gel of the control and experimental groups inside the culture insert and culturing to prepare corium mimic; a step of imaging the shape of the mimic in a three-dimension; and a step of evaluating elasticity change from the image result.
