CONSTITUTION: A method for measuring anti-oxidation ability of a cosmetic product comprises: a step of applying test cosmetic product on a potato; a step of photographing potato before and after exposing in the air; a step of measuring brightness of the potato using the photographed image; and a step of evaluating anti-oxidation effect of the cosmetic product.
Abstract:
PURPOSE: A method for measuring skin moisturizing capacity is provided to simply measure skin moisturizing capacity of a candidate material by measuring moisture retention capacity of a green-lentil jelly coated on the candidate material. CONSTITUTION: A green-lentil jelly is spread on a candidate material. The skin moisturizing capacity of the candidate material is evaluated by measuring the skin moisturizing retention of the green-lentil jelly. The evaluation of the skin moisturizing capacity is performed by analyzing an image about the moisture retention capacity of the green-lentil jelly. The moisture retention capacity of the green-lentil jelly is evaluated by measuring the contraction and a curve of the green-lentil jelly. The moisture retention capacity of the green-lentil jelly is in inverse proportion to the contraction and the curve of the moisture retention capacity. The contraction of the green-lentil jelly is measured by evaluating the thickness and the cross section of the green-lentil jelly.
