Abstract:
A white hair suppressing composition and a kit for melanogenesis promotion of hair are provided to promote melanogenesis of hair using GDNF protein or gene ciphering protein. A white hair suppressing composition comprises a neurotrophic factor receptor genesis growth factor as an active ingredient. The white hair suppressing composition promotes melanogenesis of hair by promoting expression of microphthalmia-associated transcription factor. The white hair suppressing composition is coated scalp or hair. A kit for melanogenesis promotion of hair comprises gene ciphering the neurotrophic factor receptor genesis growth factor or protein.

Another aspect of the present invention relates to a composition including three kinds of composition of cholesteryl isostearate, cholesteryl nonanoate, and cholesteryl chloride.
Abstract:
PURPOSE: A composition containing Bifidobacteria extract is provided to enhance the stemness of stem cells and to enhance adipose for beauty. CONSTITUTION: A composition for enhancing the stemness of adipose-derived stem cells contains 0.0001-10 wt% of Bifidobacteria extract as an active ingredient. The stem cell is human adipose-derived stem cells(hADSCs). A composition for enhancing skin cells contains 0.0001-10 wt% of extract as an active ingredient. The skin cells are keratinocyte stem cells(KSCs) or transit-amplifying cells(TA cells). The extract is prepared by culturing and crushing the bacteria with a homogenizer.
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.
