PURPOSE: A method for generating a heat protection factor is provided to generate a heat protection factor, thereby objectively evaluating an effect of a cosmetic product including heat protection materials. CONSTITUTION: A first area spread with heat protection materials and a second area which is no the heat protection materials are heated respectively(S1). Saturation temperature of the first area is measured(S3). The saturation temperature of the second area is measured. An energy corresponding to heat heated in the first area is divided into the saturation temperature of the first area for calculating a first energy(S5). The energy corresponding to heat heated in the second area is divided into the saturation temperature of the second area for calculating a second energy. A heat protection factor of the heat protection materials is calculated by dividing the first energy into the second energy(S6).

Abstract:
PURPOSE: A composition containing an oligonucleotide or mimic acting as an inhibitor of miRNA-526b is provided to control collagen generation and to prevent or treat aging. CONSTITUTION: A composition for controlling collagen contains 15-23 serial nucleotides of sequence number 1. The collagen is controlled by regulating the expression of matrix metalloproteinase 1(MMP1). The oligonucleotide reduces or suppresses the expression of MMP1 by hybridization with MMP1 mRNA. The composition is used for anti-aging.

Abstract:
PURPOSE: An evaluation method is provided to objectively measure the relief effect of sensory skin irritation by quantifying the relief effect of sensory skin irritation about various anti-irritants through the change of concrete threshold. CONSTITUTION: A sensory skin irritation relief effect evaluation method comprises a step of measuring the change of a threshold before and after spreading an anti-irritant to a stimulus applied to the skin sensory nerve. The evaluation method quantitatively measures the change of the threshold by using a device. The evaluation method measures the change of the threshold value about a stimulus applied to at least one skin sensory nerve which is selected in a group which includes Aα, Aβ, Aδ, and C-fiber type. The evaluation method measures the change of the threshold value about a stimulus which is applied to the skin sensory nerve of Aδ or C-fiber type.
