Abstract
A new simple method for determining sebum excretion is developed. An apparatus named “tip”, which surface is coated with a thin layer of white pigment on a black pigment layer, quickly gives black pattern of sebum by press it to the skin surface. And the blackness of the pattern is proved to be proportional to the amount of skin surface lipid. Thus, this method makes it possible, for anyone to measure sebum amount simply and rapidly. It may be useful as a reasonable indicator for the care of skin healthy and the selection of suitable cosmetics.
