A METHOD FOR EVALUATING THE SENSORY IRRITATION REDUCTION EFFECT IN SKIN

摘要

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.
